New Deep Sea Squid

texchanchan writes: "Yahoo reports on a newly discovered species of deep-sea squid, quoting scientists as saying the creatures are very different from normal giant squids. 'New species are a dime a dozen. This is fundamentally different' in behavior and appearance -- with 10 identical long skinny arms and a jellyfish-like hunting strategy. 'We don't know of any cephalopod that has arms like that.' --Michael Vecchione of the U.S. National Marine Fisheries Service. 'I had never seen anything like this creature,' oceanographer William Sager of Texas A&M says."

All squid have ten arms, but 2 are usually much longer & skinnier than the others. It seems this one has them all the same length. the 2 longer tentacles are used for feeding, they shoot them into schools of fish & then retract them. the other 8 are for propulsion.
A Soviet tanker in 1965 came across a battle between a giant squid and a sperm whale that would have weighed around 40 tonnes. The fight continued for some time and finished far below in the depths, beyond the range of the tanker's sonar equipment. About an hour after the sighting the strangled body of the whale was found floating in the ocean. It still had the giant squid wrapped around its body. But the squid did not win - its head was found inside the stomach of the whale!

A recent National Geographic article had the most amazing discovery I've seen in a long time: an Australian octopus that mimics dangerous marine animals by changing color and pattern and folding its arms.

It can bunch its arms into a flattened oval and develop brown patches to resemble a toxic flatfish, curl and hang its arms and turn light blue to resemble a local jellyfish, elongate and develop stripes to look like a sea snake. Absolutely mindblowing.

Unfortunately the pictures they selected to put on the web don't begin to do it justice.
