These exist in real life but don’t usually attack humans

If you get a leech/lamprey just stand on a fire or get a tribemate to stab it off, if this will not work simply check your tames for leeches

Put a fish basket and wait for a leech to get in it but u can also tame. Coelacanths and mega perrannna!

You can find Lamprey in the Hidden Grotto cave if anyone was curious.
