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

My favorite thing with anglers

"Hey I'm going on a pearl run, anyone wanna play bodyguard?"
Are you going to bite ammonites this time?"
"Told you it wasn't on purpose"
"Alright alright I'll go lemme get some scuba and I'll hop on the mosa"

Ten minutes later my tribemate is having to save me from two mosas, an alpha mosa, 50 anglers, 20 eels, 7 plesies all in one area

"STOP BITING THE AMMONITES"
"IT WAS AN ACCIDENT! they hide in the reefs and I hit them if they happen to be by a pearl patch! :'( "

Nope, totally biting them on purpose hehehe

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

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

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