In ARK: Survival Evolved; Mobile, and even in the regular the Island, there is an Island in the south known as South Haven Island. It consists of purely herbivores, and pteranodons. There is always at least two ankylosaurus at one time, and often more, and the only creatures on the crescent-shaped island are triceratops, ankylosaurus, brontosaurus, parasaurolophus, pteranodon, many coelacanth, and most often, basilosaurus, ichthyosaurus, and megalodons, along with far-off leedsycthis. Titanosaurus will occasionally spawn there, and, if they step off of the back of the island, its slope is too steep for any dino to easily overcome. Furthermore, the numerous metal nodes respawn rapidly, much more quickly than anywhere else, and there are silica pearls in extreme amounts in the inner beach, which also respawn practically as soon as you look away. There are also large sections of the island where you can make massive bases, even along the sandbars. I hope that this helps, Wanderers. From.: OMEGA, Hunter of Shadows.

For Ark: Survival Ascended!

Angler fish + south & east side of the ocean I’ve had best luck obtaining decent amounts, it’s all scattered so no big pods/groups.

Ocean caves also have a good bunch! Make sure to bring a sickle as there’s tons (TONS) of grass/fiber that you have to harvest before you get the silica. Hope this help!

On The Island, Silica Pearls can be easily found in the top left corner of the map (about 30 lat, 10 lon) they're seen as large white and blue stones in the water.

also put fur on cause its in an arctic zone, funny story on how i almost died in one of the stupidest ways possible

At roughly 39 59 on crystal isles you'll find thousands of them all clustered together.

Why are these so hard to get in asa

On ark mobile there’s oysters on the beach harvest them and u get like 9-15 pearls per oyster

Hope this helped

For ASA players on Scorched Earth:

Check the Obilisks. I personally found the most pearls at the Red one.

On Crystal Isles, at about 42 40 there is a little white lake. There is a waterfall in the lake, and on either sides close to the waterfall are around 1000 silica pearls, + the ones in the beaver dams. Just be careful because in my case there was a Yuty pretty close by.

go to the snow island at 30 lat, 10 lon. There are tons of trilobites which drop silica pearls and black pearls. white and blue rocks in the water (not the white and black oil rocks) can also give you silica pearls. you also need silica pearls for yuty saddles for bosses. Hoped this helped!

On mobile casual, grind riot shields and scuba masks, trust me, it will add up while you are grinding for amber and polymer/metal ingots

Beaver dams also have a chance to give silica pearls too.

If you are on the island with hydrophobia go to the arctic. It has close-to-shore lakes with silica pearls in it I got my chemistry bench and haven’t been near the deep ocean

On the island got to the south shore of herbivore island. I got around 600 in one trip

If you got to the west Ocean if the Island, you can find an underwater cave containing thousands of not tens of thousands of silica pearls. Just use your hand to collect them you’ll never need more!

Rag 75, 23 sea floor has more then you can carry also rob beaver dams

On mobile you can find them on beaches and shorelines instead of underwater

If you want silica pearls just tame an angler and go to fertile lake on abberation, got a couple thousand in like 5 mins on 3x

Above the dwarven statue on fjord is a lake in there are butt tons of silica pearls

Just comb the beaches. You’re bound to find them just about anywhere save the east side of the map. Anglers are amazing at farming these. Would recommend taming one if you’re hard pressed for pearls

Leeches can also drop them but Dododex doesn't say so
