If you are on old mobile and you wanna craft tek structures or items that cost a fortune of these things to craft, then do the "violent dance of the amphibian" dungeon as it is one of the dungeons that is available in the dunegon menu permanently as long as you have internet since the devs gave up on this game so they gave us these dungeons

Once you enter the dungeon find and open the featured loot chest and hope you get 100x black pearls (you can save scum on singleplayer)

The dungeon boss is reletively easy too it's just the Beelzemorbus and with this specific dungeon you will also get 60 element instead of 20.

After you complete the dungeon it will cost 5 amber to enter so you can wait until 8 pm est for the entry cost to decrease to 0 amber again then grind it until you have enough black pearls

Don’t even bother trying to find this on mobile

Just go to eldrich zone on crystal isles and look for big bubbles that have some black clams/oysters inside of them, put your angler fish inside the bubble, harvest, and enjoy the best black pearls harvester in the entire game, super easy, rank up for people to see this.

If you're on the island search the beaches when its raining and use a chainsaw on trilobites

If you're on singleplayer and you see trilobites or ammonites leave your game then put dino or player damage all the way up to max, then join, kill the ammonite/trilobite, use a sword or high damage tame to harvest the corpse, and you will get black pearls in the 2 digits instead of 1 or 2 with 1.0 player or dino damage.

Nobody will know since everybody can edit dino or player damage, and nobody will blame you.

On the new map, Lost Island- there is a sunken ship in the very bottom left corner. I mean, tucked almost right in the corner, where the barriers meet. If you go inside the sunken ship, to the bottom of it, you will find clams full of only black pearls. The devs have a sense of humor, I'll give them that!

On Fjordur, the only way to obtain Black Pearls without going underwater is through, one, the Magmasaur den at the volcano in a cave inside the Fire Wyvern den, or two, from taming Gachas found in Asgard. Hope this helps anyone playing on the new map.

Since I haven't seen anyone recommend this, on the Island, go to the cavern of lost hope also known as Artifact of Cunning cave and kill tusos. Make sure to bring lots of scuba tanks and some good dinos, hope this helps anyone

"This is for only mobile players. Just tame a otter and turn on his/her victim item collection from the corner side of your device and give his/her agreesion to attack target and whistle it to follow you. Then go to small fishes and punch them and wait for some time. Keep warned that your otter's have to kill and hervest that not you. If the otter kill and hervst the fish then it will give you black Pearl. But it has only 35.78% chance to give you black Pearl.This is the tip to get black Pearl safely without any damage. Jay hind

The "Dropped By" doesn't say it, but I also got 100 of these from an alpha Mosasaurus

Just become Jack Sparrow and summon Calypso

first tame an ichthy then go to rag about 75,23 more black pearls then you can carry on the sea floor and not to dangerous just keep an eye out for megs

When you want black pearls in great quantity, here are some things I suggest.

1: Ragnarok: Vikings bay. Bring a good crossbow to one shot any water scorpions, they drop TONS of black pearls.

2:Extiction: Gachas. Sometimes when taming gachas, you can get one that produces black pearls. They produce in big quantities, and for me is by far the safest and easiest way to get the black pearls. Like if this helps!😄

Be careful if you are planning to kill (eurthy...smth )... sea scorpions . They give blackpearls but can instantly make you unconscious in one hit . Hit with a bow / crossbow at them. Hope this helps

On the island map, this is such a pain to collect. Takes ages

I just threw a my otter in water thinking I could get some fish meat but when I came to it, it gave me 30 pearls! I kept doing this until I got 230 pearls ands that’s how I got a tuso

I just found that when I command otters to attack fish in rivers, the highest rate of harvesting black pearls is from salmon, followed by piranha and coleacant.I had a team of 3 otters that slaughtered a total of ~30 fish and harvested 27 black pearls. Big profit...

Pain in the ass to find on mobile

The Island- There are 4 steps.

1- Kill EVERY Trilobite you see and use an axe to harvest them.

2- Tame and train a dinosaur to ride underwater (I suggest Baryonix. It’s fast on land and in water and can breathe air and water and fight like crazy)

3- Ride your Dino to the bottom of the Ocean.

4- Ride around the edge of the map and kill every Trilobite, Sea Scorpion, Ammonote and Squid you see.

I got 100+ black pearls going along all 4 edges.

Carnivorous plants in Gen2 give black Pearls, harvest them with best chainsaw you got
