These things do a lot of damage to all fish including jelly’s. They are very useful for collecting toxins. My tamed pela on brutal one shots most jellyfish that has like over 1k health. This bird is perfect for making lots of toxicant arrows. They harvest lots of polymer from young penguins. Great tame for finding otters. These birds are very underrated. I also soloed an alpha carbo with one by luring it in the water and using my speedboat bird to kill it
