Still Waters Posted October 29, 2020 #1 Share Posted October 29, 2020 Ram's horn shells are small, delicate spiral structures beachcombers can commonly find throughout the world. Yet despite their ubiquity, the original owners of these shells are extremely elusive. Until now, we've never had footage of a single one in the wild. In the twilight zone of our oceans, at the tips of sunlight's fingers, a remotely operated vehicle (ROV) has now delivered the first footage of a ram's horn squid (Spirula spirula) in its natural habitat. This strange-looking cephalopod is a wee little thing barely 7 centimetres (under 3 inches) in length, with eight arms, two tentacles, a pair of bulging eyes, and a general muppet-like appearance. https://www.sciencealert.com/first-ever-deep-sea-footage-of-a-ram-s-horn-squid-has-scientists-freaking-out 3 1 Link to comment Share on other sites More sharing options...

My parrott loved chewing on cuttlefish bones. Cuttlefish - Wikipedia 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, which is used for control of buoyancy. 1 1 Link to comment Share on other sites More sharing options...

But damn, the shell was not that big related to the tissue part... Some structure are present in other camalari too. 1 Link to comment Share on other sites More sharing options...
HandsomeGorilla Posted November 3, 2020 #5 Share Posted November 3, 2020 (edited) Another one where you wonder if they're from another planet. I love squid. They're so delicious, too. Edited November 3, 2020 by HandsomeGorilla Link to comment Share on other sites More sharing options...
