yeah, i combined two different things to make a third new thing. i combined a calla lily with a rare scalicanlaloopy flower; i call my hybrid flower a callaloopy. that's amazing, lisa, you're totally going to get an a. oh, i'm just so happy the plant bloomed. yeah, it opened all right. yeah, i was worried that the flower wouldn't bloom, and if it didn't, i couldn't prove that my plant's a hybrid of these two. ♪ i see you got your little flower to bloom...it's cute. but you're never going to beat my science project. it's a hybrid of a garden phlox flower and a holly bush, and i call it...francine. if you say so, francine. come on hector, i'm going to get some water for my callaloopy. yeah. ♪

franscent by francine. what smells? i do... franscent by francine... i cannot believe the nerve of francine, stealing your flower and turning it into perfume for science class? it took me weeks to grow that hybrid flower and a day before it's due all i have to show for it is a pot of dirt and a bare stem. well, the stem is the main part of the plant that grows out of the ground. why can't you present that? because i need the actual flower to prove it's a hybrid. why can't you plant another callaloopy? i could, but it wouldn't bloom in time. i can't believe that francine! i know, i only have one day to come up with a new project. you know, and what really gets me is that francine is going to end up smelling like a rose. whoa! whoa!

language invention! the dolphin decoder. dolphins! yes! i've been waiting forever for a dolphin adventure. you kidding me? here's my list of everything i've always wanted to say to a dolphin but didn't know how. well, this could be our chance. but first, we have to figure out the language. the sounds and words of dolphinese. who's going to teach us those? they are. chris: hoohoo! bottlenose dolphins! (all cheering) you guys take the hydrophone part. i'll take the receiver to program the sounds. dolphin dive! ha ha! jimmy z: dispatching amphipod. good luck, team dolphin. make a splash! chris: wow! hello, dolphin pod. it looks like this one has about 14 dolphins, young and old. (dolphins squeaking and clicking)

(martin chuckling) a couple 4-year-olds. i think they're talking about us, chris. yeah, i hope they're saying nice stuff. (dolphins squeaking and clicking) what are they saying? click, whistle, whistle, click click. oh, that's not good. it's not? i have no idea! it's all dolphinese to me. okay, well let's try this thing out. listen up dolphin pals we've got something to say. i'll pick a whistle from the database and see if we can figure out what it means. how will we know? from their reaction. here goes. (clicking) (grunting softly) whoa! (laughing) whoa! whoa...! whoa...! (yelling)

so, have you figured it out yet? no! not yet! well, that whistle definitely meant something. yeah, like, "let's take these guys on a crazy ride "till they can't see straight!" whoa! stop! slow down! (yelling) (sighing) (dolphins squeaking and clicking) (sighing) (moaning) or they could be saying something a little simpler like, "let's play." they are one of the most playful creatures in the world. (groaning) okay, so we get it, we get it. now we know what that click-whistle means. yeah, the dolphin word for "let's play" is this one right here. (clicking) martin! uh oh! you said it again! whoa! whoa! help! while they're having fun, we've got to get to work on getting the sounds we know into a dolphin power suit. well, see the

blowhole that the dolphin breathes from? right beside it are chords. they vibrate like a guitar string to make the special clicks and whistles. that makes sense. vibrating things make sounds. so if i incorporate those structures into the suit we should be able to reproduce the special dolphin sounds. kratts: whoa, whoa! remember us?? how many special whistles and clicks do dolphins make again? chris: hundreds! martin: at least! thanks. whoa-- ah! oof! no problem. (groaning) okay, you two win. you're definitely the most playful creatures we've ever adventured with. yeah, even adult dolphins play. one of the only animals in the world that still plays when they're full grown. (dolphins whistling and clicking) whistle and click. ha! that's what i'll name you two. you're whistle and you're

click. (dolphins whistling and clicking) wait a second. i've got to play that back. (whistle and click) (grunting) incredible! martin, they already have names! that whistle click is his name. you're right. dolphins actually have names-- personal whistle clicks that are their very own dolphin names! and is this your name, click? (squeaking) (grunting) that's it all right! chris, we need dolphin names. i'll be... agah-agah-agah-gah! i don't think they can say that. must be your jersey accent. put a little more dolphinese into it. okay, how about this? (whistling) that's it. that's me martin, in dolphinese.

and i'll be... (whistle-clicking) (imitating) yes. i can't believe it. we're talking to dolphins! aviva, koki, we just made friends with dolphins! this is working better than i thought. keep going, guys. i'm uploading all the words and their meanings into the dolphi-speak database. don't forget our names. (whistling) and... (whistle-clicking) i've got them. i think you've found some buddies that can really help us here. yeah, dolphins make lifelong friendships with one another and whistle and click are definitely best friends. try another one of those mystery whistles in the database. okay, hang on. let's see.

hm. ♪ hmm... got it! how about we give this one a try? (squealing twice) (clicking) oh, what did we say this time? chris: whatever you said, they're interested. hey, i always have something important to say even when i don't know exactly what it is. (squealing) hey, wait for us! (squealing)

(squealing) (clicking) hm, i'm picking up some clicking sounds from the pod-- but super high-pitched. they're echolocating! hunting for fish! that whistle i said must have meant something like "fish over here!" or "let's eat!" (whistle-clicking) oh, click's looking for whistle. she's calling his name. must want to hunt with him. (laughing) cute! well, we should help them find fish, especially since i'm the one who said i was hungry. aviva: dolphin power suit coming up, guys. a couple of quick adjustments and you'll have the prototype dolphin power suit, complete with echolocation power. yes, looks like the echolocation works pretty much the same as the bat and sperm whale. they send out a super high-pitched click sound through this part of their head, the melon. the sound bounces off objects, like schools of fish or other prey, then bounces back, and

the dolphin picks up the sound waves making a picture of what's up ahead or out of sight. great, so i modified the bat and sperm whale echolocation programming and that should do it. dolphin discs are ready guys with echolocation and click-whistle dolphi-speak features. awesome! okay, click, ready for a couple more dolphins with suped-up dolphi-speak power? activate dolphin powers! ♪ oh, yeah! now, this is what i call swimming! (clicking) the suit's working. it's picking up the clicks just like the hydrophone. we still have to figure out what they mean, though. (clicking) chris: a school of mullet fish.

i bet that whistle means "i found food. this way!" aviva: follow those dolphins! (clicking) hey, are you getting any of this? no, but it seems like they're making a plan for the hunt. problem is, they're doing it in dolphinese. well, how hard can it be? let's just follow their lead. huh? (squealing) what's wrong, click? (whistle-clicking) huh? what? whistle? you're saying whistle. what about him? (squealing) that must be some kind of distress call. i think she's worried about whistle. (squealing) uh-oh, i'll check it out. okay, we'll stay here and decode this hunting stuff. okay guys, let's do this. catching fish, dolphin-style!

(dolphins click-whistling) got it. that click whistle must mean something like "circle the fish!" no problem. i'm with you, guys! oof! sorry, wrong way. this way, right? (whistle-clicking) ha! i got this now. we're herding the fish into a tight ball-- a bait ball! this is genius. talk about a smart creature, and by communicating you can cooperate and work together. (clicking rapidly) oh, up. got it! that whistle means move them up. you're pushing them right to the surface, aren't you? so they'll have nowhere to escape to. ha! brilliant! oh, now the feast begins! dinner time for dolphins! no wonder they're one of the smartest creatures on earth: a language smart hunting strategy and one of the largest brains for their size.

(gasping)

uh-oh. just kidding. nice sharky. whoa!

(beeping) hm... echolocation engaged! who can find it first-- whatever it is.

nothing but sand underneath more sand. you sure there's something around here? (echolocating) amazing! that sponge she uses is to protect her nose when she shovels in the rough sand. hey! i was just about to find that fish. (squealing) koki: communication alert! we're having trouble getting a read on martin's location. i had a signal but it's disappeared. disappeared? how is that possible? i don't know, but last i picked it up, it was to the east. let's head in that direction see if we can find him. yeah, we'll spread out; i'll head out this way with an echolocation search. he's still out there, whistle. i know, sharks and orcas. they're your only natural predator especially for baby dolphins. i'm still not able to transmit from

inside this wreck. maybe if i can just get out in the open a little bit... whew... or maybe not. oh, so much for my creaturepod. (squeaking and clicking) oh, good idea, whistle! maybe dolphin communication will help us get out of here. let's just hope someone hears it, and soon. we're picking up a sound. it's a dolphin call. amplifying sound. that could be a distress call-- a dolphin in trouble saying, "help!" (whistle-clicking) that's whistle's name. it's whistle calling for help! and it's coming from down there. aviva: from that shipwreck? aviva! koki! over here! we see you! we're coming in to get you! oh, nice work, whistle. look out!

ah! shark! no kidding! we gotta get out of here! quick! martin, we can't get past him! he'll crush our little amphipod. oh, great! this shark's never gonna let us get out of here. (beeping) uh-oh, i'm running out of air. and so are you. it's been about 20 minutes, and that's about as long as you can stay down without coming to the surface to breathe through your blowhole! if we don't get to the surface soon, we're in big trouble. hm, nothing in this direction. aviva: chris, we found them but we need help. they're trapped by a huge great white and running out of air! uh-oh. i bet the pod knows how to deal with sharks. if only i could tell them what's going on. you can. talk to them! you know dolphinese. yeah, but not that well. i mean, the whistles, the clicks-- it's confusing stuff. you've got

to try. head west. hurry! okay pod, listen up. we've got to talk. all right, let's see. which whistle click? uh, here we go. (clearing throat) (whistling) oh no, i think i just told them eating is dangerous. wait, wait, wait! wait, wait. uh, i mean-- i mean this: (whistle-clicking) ha, they understand! i'm talking to dolphins. that counts as a full sentence, too. come on, i'll show you.

aviva: what?! is he crazy?! we've got to do something. uh, distract the shark! yoo-hoo! shark! koki: giant amphipod over here! i can't believe we're doing this. there goes the engine. we've lost power! aviva: oh no! (gasping) uh-oh! to the creature rescue! use the shark defense! (thumping) (thumping) hoo! yes! that's dolphin power to the creature rescue! what a defense. just in time, bro. how'd you round up the whole pod? hey, when i talk dolphins listen. check

it out! some of the dolphins circle and protect the young ones from predators. while the other ones counterattack. when you have sharks and orcas as your predators, no wonder the dolphins have a tough defense. (clicking) see ya. we need air. (gasping) we did it! we did it! (crunching sound) uh-oh. koki: now we did it! we're going down! guys! help! no problem, we know dolphinese. okay guys: (whistle-clicking) let's eat! how can he be telling the dolphins to eat at a time like this? koki: ooh, when i get my hands on them... (clicking rapidly) good work, gang. going up! amazing! the dolphins' feeding behavior is saving us. i had no idea speaking dolphinese would get me out of a jam like this today. (cheering)

what an adventure! mission accomplished! we learned dolphinese from the masters. and even used it to talk to the pod on a rescue mission. and made some great new dolphin friends, click and whistle. (dolphins squeaking and clicking) we helped them and they helped us. by the way, how do you say "thanks" in dolphinese? that one, right there. oh, okay. here goes. (clicking "let's play") whoa! whoa! what'd i say? "let's play." you said, "let's play!" chris: gotcha! koki: ooh, i'm going to get you, chris! enjoy the ride! with one of the most playful intelligent, and just all around amazing curious creatures on the planet! wahoo! double spin! (laughing)

so dolphins have a complex communication system a type of language that scientists are still trying to understand. and we're here with our friend kel from the dolphin communication project, who's trying to make sense of the dolphins' clicks, whistles, and body postures. all set, kel? hydrophones are set. they'll record everything the dolphins say. all right, let's go! (clicking) chris: up there! one dolphin touching the other with his fin! that's fin rubbing, a sign of affection between two dolphins. those guys must be pals. martin: kel and her team have put together a picture database of the dolphins, and can tell who's who by their different spot patterns and scars. that, plus the hydrophone recordings are used to understand what the dolphin sounds mean. scientists have identified about 200 different sounds so far-- sounds that mean things like "danger," or "come on,

this way," or, of course, there's always, "let's play!" (clicking) chris: it's fascinating that some scientists now believe that dolphins have their own signature whistles and clicks, or names. i'm going to go try and introduce myself. i'll go with ee-whoo-ee-whoo. ee-whoo-ee-whoo. (dolphins whistle-clicking) nice to meet you. martin: did you notice how the dolphins are making sounds but their mouths are closed? that's because dolphins don't talk with their mouths like we do. they make their sounds out of their blowholes. chris: dolphins have amazing creature powers! speedy underwater, they can jump out. they can talk underwater. dolphins are one of the most awesome animals in the ocean. wow, that was incredible. two curious creatures, humans and dolphins, swimming together, and trying to understand each other. and the more people study their communication, the closer we get to really understanding these cool creatures, right, kel? that's

right, and we'll look at this video and the acoustic as soon as we get back to the lab. all right! see you later, dolphins! martin: keep on creature adventuring! (clicking) you know, they call them groundhogs and whistle-pigs. but a groundhog is really a rodent. so, her closest relatives are squirrels, ground squirrels, beavers and porcupines. okay, you want to get down and eat some more? there you go. but whatever you call them a groundhog is one cute, roly-poly ground-loving rodent. did you know a group of lions is called a pride? it's made up of mostly females, the lionesses, and all of their offspring the cubs different cubs of different ages from different mothers. in a pride there's only one or two or sometimes three full grown males. the pride is a unique

family group for cats. in fact, lions are the only one of all 36 species of cats that lives in big groups like this. great climbers? it seems odd that such a slow, roly-poly creature could move easily up a tree. but he can. using his sharp claws and his slow and steady technique, branch by branch he can get right up high in the treetops. and that's a good place to be for a bark-eating rodent the porcupine. announcer: listen up as martha speaks! martha: that colleen really knows how to scratch an ear. boy: come back in 3 months. that's almost two dog years. announcer: "martha speaks." weekdays on pbs kids or watch anytime you want at pbskids.org!
