This is the species i was working on:
(still a work in progress)
1) Flappy slug like ears
2) the eye color can be any colorand it covers the whole eye except the pupil wich is always white
3) their most important feature. they have conch/shell pieces.
-conch pieces can have any shape and size (for example they can look like horn on their heads or spikes on their backs or arms or anywhere in their body) conch pieces can also be flat like scales or round
-Conch pieces are always hard (like seashells or snail shells) unlike the main body wich is always squishy
-Conch pieces can be any color but are always glowy and leave a sparkly trail behin when they move
-they cant take off the conch pieces but they can shed off or grow new ones over time
4) slug like flaps under the arms
5)Long prehensible tails they use like grappling hooks for moving around on their natural habitat
6)they have no bones,skin, fur feathers etc. they are 100% mollusc body (like slug or octopus etc) They can have hair on their heads tho, for looks ouo
7) their natural habitat are underwater ruins of ancient cities or towns that sinked or got flooded. they can live in a sinked ship if its big enough for the family (they are comunities dont live alone). they dont like underwater caverns but can live there if theres no other choice. they can not live on open sea or lake because they cant swim good without using their tails to grap on walls
8 ) Their diet is 100% plants
