As of the latest patch they collect pearls when you bite them.

I don’t know what use they have when tamed but the gel is needed for the electric prod which is really good for pvp

This is kind of horrific amd not the most humane thing, but here goes. You can get a few of these, breeds them, and kill the children for angler gel. Just saying 😶

P. E. A. R. L. S. That's all you need to know about this amazing creature.

Who thinks they should produce angler gel in their inventory over time like basilos and tusos

Level up melee to collect more pearls. Level up speed to outswim creatures.

On ASA go to bottom left of the map all the way to world border corner for loads of pearls

Best creauture in the game for silica pearls, but are week so will need a strong bodyguard

People keep saying use angler gel for fuel, but that’s a waste. Use wood so you can then get charcoal for gunpowder, something that you constantly need.

Want infinite fuel?

1. Get yourself a simple underwater tame like a meg

2. Kill anglers for gel

3. Store and keep burning in standing torches or refinery

( STANDING AND WALL TORCHES BURN BLUE)

I collect this with a plesiosaur and can burn 700 metal with just 30. Lucky I collected 5000
