I saw a comic about a Tortle contracting Lycanthropy but wouldn’t Lycanthropy be an exclusively mammalian curse/affliction ?

D&D creates its own mythology. While the typical werewolf stories might make it seem like there can’t really be a were-turtle, by D&D rules, there can be.

Lycanthropy isn't a real thing, so it doesn't have to follow any real-world rules about how diseases work.

Actually, there is a psychological condition called "lycanthropy". But yeah, in D&D it's a magic curse so biology and physiology aren't factors.

 The source of Lycanthropy will indicate if it can only affect certain creature type, otherwise there's no such limit.
