cuttlefish : any of various marine cephalopod mollusks (order Sepioidea, especially genus Sepia) having eight short arms and two usually longer tentacles and differing from the related squid in having a calcified internal shell — Webster
Cuttlefish or cuttles are marine molluscs of the order Sepiida. They belong to the class Cephalopoda, which also includes squid, octopuses, and nautiluses. Cuttlefish have a unique internal shell, the cuttlebone. Cuttlefish also have large, W-shaped pupils, eight arms, and two tentacles furnished with denticulated suckers, with which they secure their prey. They generally range in size from 15 to 25 cm (6 to 10 in), with the largest species, Sepia apama, reaching 50 cm (20 in) in mantle length and over 10.5 kg (23 lb) in mass. — Wikipedia

- The secret life of baby octopuseson September 23, 2021 at 1:29 pm
Some of the most amazing creatures live in the deep blue sea. Cuttlefish, squids and octopuses, for example. These soft-bodied cephalopods have a strikingly sophisticated nervous system, camera-like eyes, three hearts, and an extraordinary ability to switch the color and texture of their skin to mimic their background in the blink of an eye.

UNSW marine biologists have developed a method for identifying Australia's soft corals that are most vulnerable—and most resistant—to rising sea temperatures and episodes of coral bleaching, and therefore, which species are in most urgent need of protection.

Cuttlefish can remember what, where, and when specific events happened—right up to their last few days of life, researchers have found. The results, published this week in the journal Proceedings of the Royal Society B, are the first evidence of an animal whose memory of specific events does not deteriorate with age.

A landmark scientific study involving marine biologists from Greece, Turkey, Cyprus, Libya, Italy, Tunisia, the UK, the US and Malta documenting instances where native Mediterranean species have preyed upon two highly invasive marine fish—the Pacific red lionfish and the silver-cheeked toadfish—has just been published. Prof. Alan Deidun, coordinator of the Spot the Alien Fish citizen science campaign and resident academic within the Department of Geosciences of the Faculty of Science, is a […]
