Help with my bio project?

[u/Awff_da_waff]

I’m working on a spec evo project on a very VERY iron heavy world,(funfact:the oceans are blood red and almost all plant life is yellow!)
I already have a couple critters and I mostly need inspo anything is welcome!

Maybe take some inspiration from echinoderms? They’re pretty bony and scaly for an invertebrate and is also my favorite invertebrate phylum.
