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

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.

YOU CAN RIDE THEM WITHOUT A SADDLE

They will also light up the area in front of them with a soft, bluish light

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

Can be transported in fish basket but sometimes when you release them you can't ride them or access their inventory

You can fix this by cryopodding it and throwing it out again

After you get a mosa kill these and you will have so much anglergel you won't know what to do with it.

Probably because there are already not that many uses for angler gel.

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

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
