'HOMEWORK'
This is Scientific American, 60 second science, I am Susan Berd.
More than 15,000 feet below the susan of the ocean, it is darker than the moonless night, but even in this murky world, there is constant activity, including groups of humble squid, each the size of a small adult human. Darting around in search of fish.
"You can think them as rocket ships, they jet through the water, they engage......,they are always looking out for an opportunity to eat", Stanford University biologist, Van Burford. He says feeding in a group requires careful navigation. "these animals are.., they are pretty agressive,so there is probably some risk to group living. We think a lot of communication they do in these groups,...,like imagine driving in heavy trafic with bunch of agressive drivers, say down in Losangeles, thank goddness, you have turn signal and break lights and horns on your cars, because that prevent a lot of catastrophy from happening. Burford thinks humble squids communicate in the dark ocean by using their own form of signalling.
They do it by turning their bodies into animated message words, how? Like other...,they can rapidly change the pigmentation pattern on their skin, by contracting and relaxing their muscles, what's more, their bodies can glow, they are creating a ... for their pigmentation patterns , so it becomes like an e-reader, something you can acturally read in the dark. They are essentially like, you know, selectively revealing and concealing different parts of a glowing body, producing patterns on top of the glowing body. Burford expects that squids could be combining different pigmentation patterns to create complex signals. So each of those elements could mean something and they might have potential to combine them to generate more meanings, to find out, his team attached cameras to remotely operate the vehicles in order to study the squids behaviors. "we looked how they arranged their patterns in sequence during prey capture events".
The researcher found preliminary evidence that the sequence of patterns varys constantly in specific contacts. For example, the squid tend to flicker when many other squids are around or darken when pursuing prey only to change their pattern just before striking, the study is in the proceedings of the National Acadamy of Sciences. Burford eventually hopes to do underwater experiments in which the squids will show feedbacks of their visual signalling, vitural glowing squid if you will, their reactions should be illuminating.
Thanks for listening for scientific American, 60 second science.
