I’m trying to understand how/what the cuttlefish attacks the crag with - but I can’t tell if the white thing that comes out from under its… “Cthluthu mouth-tentacles” is a tongue, a beak, a bone, a pincer, a spine, or something else. Wikipedia’s page on cuttlefish anatomy doesn’t help, unfortunately :/

Cuttlefish, like squid, have 8 short tentacles around the mouth plus other 2 much longer tentacles, which are thinner except for their ends, which are expanded and which have suckers. The 2 long tentacles are normally kept coiled and covered by the short tentacles, so they are not visible. When the cuttlefish catches prey, the 2 long tentacles are extended together extremely quickly and they attach to the prey (much like a chameleon catches insects with its very long tongue). Then the 2 long tentacles are retracted quickly, bringing the prey to the mouth that is also hidden between the 8 short tentacles. The mouth has a beak, similar to a parrot beak, which is used to kill and consume the prey. See the drawing: https://en.wikipedia.org/wiki/Cuttlefish#/media/File:Seba_molluscas.jpg https://en.wikipedia.org/wiki/Cuttlefish#/media/File:Seba_mo... The drawing shows the long tentacles as you could see them on a dead cuttlefish. As I have said, in the living cuttlefish you can see them only for a fraction of a second, when catching prey and bringing it to the mouth. Also, the 2 long tentacles are extended together, one besides the other, they never stay limp and separated, like in the drawing or in a dead animal.

I bought a biology style painting because I liked the intentional dead-animal style (both a bird and some insects).
