So apparantly corrupted creatures give black pearls, anglergel and stuff luke that when they die, i found this out while on ark, (had super high drop rates so on officail its probly super rare) also corrupt rexes drop the most i find.

I use a Poison Wyvern to clear out the bubbles at Elderich at CI. Then I use my angler to get the Black Shells.

Go to fertile lake on ab, cuz there are a ton of trilobites there. It’s an easy (but slower) way to get black pearls. Harvest with angler (manta gets pearls too sometimes) and enjoy the riches. After just a little bit of grinding on slightly increases settings (2.5 I believe) I have over 50 pearls

Swamp

This is just my strategy

Ragnaroc, sunken ship, shoot too kill, don't touch the water floor

Guys on the New map lost island I found tons of black pearls in cave where artifact of strong is in water

on ragnarok, you can also bring your farmer tek stryder to 78.3 - 20.6, just go underwater farm black pearls with it. you might need another dino or friend to get ride of megalodons.

p.s you can also find black peals around 54.1 - 18.9 too.

Tame a gacha or wait for the biom with the black peals on gen2 (use a stryder)

I still have not found a way to gather pearls with a tuso but the GACHA is through its production lines

Gachas do it just tame a few then separate them a ton

If you play on extinction just kill some corrupt rex they don't drop much and if you feel like trying you could get a gacha with black pearl production and all you have to do is feed it owl pellets and stone

If u go to rag and get scuba or a water dino go down into the water at Viking bay near the cave and kill this shrimp things u get A BUNCH OF BLACK PEARLS

Kill trilobites and mine the dead bodies with an Axe

use a gacha with pellets, around 30 per crystal

I got 34 pearls from killing a normal tusk in ark mobile, it was really easy, I brought it to herb island shore and shot it with a crossbow until it died, be careful tho because they can grab you on land if you’re close to the water

If I did my math right then killing 2 tusos and buying a balm should be enough to tame a low level

Go fishing!!! There is a small, small chance u can get some pearls to tame the kraken, or even make tek!

Ragnarok top right of map there’s a sunken ship surrounded by eurypterid they continuously spawn so you can either use a crossbow to kill then harvest with a pick or get a Tuso or something and rack up pearls

Get yourself a sea otter. The adorable little guys gather silica and black pretty well. Last I checked, from harvesting fish and trilobites.

Just kill those weird annoying lobster things at the bottom of the ocean

They can give lots of black pearls and the white ones and you will need theses for Tuso

Abberations Grave of the Lost has a lot of these watch out for Nameless

I was trading black pearls To somebody and he took him and killed me I was like super super super super mad😡
