This thing is deadly, was moving my Rex's across the river then found 3 feeds "Your t-rex has been killed by a coelacanth"... F for Johnny, ham, wom.

If you actually wanna tame one of these, I believe you need a fish basket

Run if you see the fish it can kill a giganotosaurus

This thing is massive and will destroy your whole base be carful

Otters are around today too
Also to kill them just punch a bit

Find it in the river, kill it and there you go, drag its dead corps around and enjoy :) ( until it decomposes )

Tamable using fish baskets from aberration.

You can kill this living fish and take it's meat. But the heinas piranhas keep coming and attacking be careful

Dont tamd it, its gonna starve due to it being unable to eat
