I am not doing anything wrong, as far as I can see. The [OUTSIDER_CONTROLLABLE] at the end of both was me testing if they could exist at all. And they couldn't.
Well, I'm not 100% but there's a couple things I'm noticing straight off that are probably wrong with the basking shark man: you want [APPLY_CREATURE_VARIATION:ANIMAL_PERSON_LEGLESS] I think, and it would be a
TOOTH_BITE_ATTACK or MOUTH_BITE_ATTACK (and TAIL_ATTACK instead of KICK_ATTACK). Also even if you get them working, bear in mind basking sharks are [AQUATIC] so they
might air-drown if you try to take 'em onto dry land in their current configuration (unless the animal person creature variations remove [aquatic] tags and the like, which they... probably don't?). ie if you were making a shark man empire entity in the swamps, they all died within moments of being created and that might be one reason why you can't play as one even if you fix the tokens I mentioned ITT.
EDIT: In the same vein, your snapping turtle man actually
should have BEAK_BITE_ATTACK.

I don't know what you used as the template initially, but that's the likely relevant portion of the regular non-alligator snapping turtle man raw I just pulled off the wiki. Edit the names as appropriate (and use the missing bottom bit from your existing creature raw) and it should work?
Millionth edit, but this was the whole reason I responded in the first place: I feel like they'd probably have at least spawned into the world even with these issues? You just had their bite attack tokens switched around after all. I am an idiot though. If you know what you're doing just ignore me when I tell you to double check and make sure your mod file and the first line in said file are the same. ie creature_birds.txt starts with:
creature_birds
[OBJECT:CREATURE]
etc
If you're just adding these entries to the existing raws, couldn't hurt to double check that you didn't accidentally backspace a character out of this portion of the file but you're probably good.
