but since you insist: did you know that crocodilians are part of the diapsid vein of amniotes. this means that their skull has two sets of fenestrae or little holes in them. these, alongside birds, are the only extant members of the group Archosauria, or the dinosaurs and whatnot.
a really neat thing about them is that they're the only non-mammalian vertebrates that have tooth sockets. and they can lose teeth and replace them throughout their entire lifespan.
they're also have really involved parental care, wherein the mother will make a little mudhut for the eggs to incubate them and will care for the hatchlings for a good while. there have even been some reported cases of the mother crocodilian excavating little ponds to allow the hatchlings to practice swimming without running the risk of predation. if you have any questions you're free to ask them sweetheart
