If you want to make the fish more accurate, remove its upper tail fin.
Homocercal tails are characteristic of rapidly swimming
osteichthians, not of crawling sarcopterygians. Shell portrayals
suffer similar problems-it's hard to find a schistosomiasis life cycle
without a glaring error in the snail host.
