Amazing Cephalopods

This is a shameless cross-post from Rebreatherworld, but this video is too cool to not share.

That last one was pretty incredible...

That last one was pretty incredible...

Yeah, I had seen that last one before on youtube, but this one is MUCH better quality video. I just gathered up my wife and 2 daughters (3 and 7) and said "Come here. We're going to learn about cephalopods". The video was a big hit. They had me replay it twice more.

I have seen the SD version also.

I think these animals are amazing. With cuttlefish, they have 3 hearts pumping hemocyanin (copper protein) based blood, a poor oxygen transporter, hence the need for 3 hearts, and they have layers of pattern producing cells- chromatophores, leucophores, and iridophores.

I do believe though that the class cephalopods is pronounced "Kef-uh-low-pod", not Sef-uh-low-pod. Kephale is ancient Greek for"head" so cephalopod gives us "head-foot".

I think videos like these and excellent presenters like the gentleman in the video morph entertainment with ocean ecology and bring it to the masses, and that is always a good thing.

The various cephalopod morphing footage by Roger Hanlon, as shown in the David Gallo talk, are discussed in this interesting article:

Interesting thought. "kefali" is, indeed, ancient Greek (and modern Greek, for that matter) for head, so it should be pronounced the way you state, but unfortunately the accepted pronunciation for the word accodording to dictionary.com is:

ceph·a·lo·pod // Audio Help /ˈsɛfələˌpɒd/ Pronunciation Key - Show Spelled Pronunciation[sef-uh-luh-pod]

Just call them "Taco".

[Sarah]

Well, they also mispronounce the Boston basketball team as the Boston Sel-ticks" instead of the proper Gaelic "Kel-Ticks".



What amazing animals cuttelfish are....

Thanks for the video. I just saw it yesterday, only to also find out that Roger Hanlon (responsible for the second half of the videos) is coming here to MIT today to give a talk on cephalapods camouflage.
