Mollusks

An Australian teenager had a lucky escape after being bitten by an extremely toxic blue-ringed octopus. A toddler also came close to touching the deadly cephalopod.

Two new species of pygmy squid have been discovered off Okinawa and named after mythical creatures.

The margarita sea snail, which shoots out a toxic mucus web to catch prey, was discovered on a coral reef in the Florida Keys and was named after Buffett, who died on Sept. 1.

This frilly slug lives in the mangroves of southeastern Asia and Australia, lounging in shallow pools of water and scraping up algae from which it gains the ability to photosynthesize.

This parasitic worm crawls into the eyestalks of snails, takes over its brain then pulsates to make the mollusk look like a dancing caterpillar.

On an expedition in Hawaii, a remote underwater vehicle filmed a dumbo octopus swimming with its ear-like fins near the seafloor. The pale white creature is one of the deepest-dwelling octopuses on Earth.

The seven-arm octopus, which actually has eight arms, is one of the largest octopus species and is rarely seen by people because it normally dwells in the deep sea.

Footage of the rare squid, Grimalditeuthis bonplandi, was captured for only the 2nd time ever during an expedition to explore hydrothermal vents off the Galapagos Islands.

The see-through cephalopod was spotted by researchers exploring the deep sea surrounding Alaska's Aleutian Islands.

As Cold War tensions rose, Gregory Bateson was busy observing two solitary octopuses learning to live together in a single tank — and it gave him an idea about managing geopolitical relations.
