Pearls can be obtained in the same way as all other sea creatures, but they are not listed in the Critterpedia! They are technically a DIY Material instead.

Deep Sea Creatures - How To Catch

Catching Process

You Need The Wet Suit To Dive

In order to start diving, you'll need to purchase a Wet Suit. The Wetsuit can be purchased at Nook's Cranny after you've updated to Ver. 1.3.0. You can also wear the Snorkel Mask while gathering sea creatures too!

Tips On Catching Sea Creatures

How To Tell Apart Different Sea Creatures

• Check the size of the shadow
• Check the bubbles, especially direction and amount
• Check the speed

Judge Based On The Shadow Size

After diving underwater, it's possible to differentiate between creatures by the size of their shadow! When hunting for a particular creature, make sure to look up its shadow size beforehand!

The 4 Shadow Sizes

Ex.Small	Small	Medium	Large

You can tell which sea creature you can get by looking at the shadow size. Check each sea creature's shadow size from the sea creature list above.

Check The Amount Of Bubbles

Sea Anemone	Acorn Barnacle

Another way to tell which creature you can get is by keeping a close eye on bubbles it produces. The picture above shows how the Sea Anemone actually has a very particular bubble pattern, making it quite easy to spot.

Some Sea Creatures Move

Some sea creatures move away from you when you try to catch them. You can also identify which sea creature it is by how fast it moves.

Can't Catch Up To Fast Creatures

When diving underwater, it will be impossible for you to catch up to the fastest creatures. Don't press the A button at all and approach them from above!

The Cornering Method

One strategy you could employ with these fish is to simply drive them to the edges of the rope & corner them. Once they have no way out, you'll be able to catch them with no problem. The only downside to this method is that it might take some time depending on your location.

Process

The Sneaking Method

By simply not pressing the A button and swimming up slowly to your target, you can get close enough to catch it. You might fail when trying this against the fastest critters, but if you're persistent you should get it.

Process

Sea Creature Uses

Donate To Blathers

Just like fish and bugs, you can donate sea creatures at the Museum. Most importantly, Blathers will give you some interesting commentary on every creature you donate!

Sell Them At Nook's Cranny

You can sell sea creatures at Nook's Cranny to earn bells. Sea creatures are more somewhat more valuable than fish so this might be an efficient way to earn bells fast.

Rare & Expensive Sea Creatures
Gigas Giant Clam 15,000 Bells	Spider Crab 12,000 Bells
Giant Isopod 12,000 Bells	Vampire Squid 10,000 Bells

Use Them As Decorations

You can use sea creatures as decorations by placing them in your room or on the island. Sea creatures have unique appearances when placed out in the open!

Give Scallops to Pascal

Pascal is a Sea Otter that will show up once a day to ask for a Scallop that you have caught. Give it to him and he may award you with a furniture recipe, mermaid clothing, or a pearl for it!

CJ - Fishing Challenge & Selling Sea Creatures

Does Not Count Towards The Challenge

Sea Creatures do not count towards CJ's fishing challenge! If you talk to CJ with only Sea Creatures in your inventory, he'll just point out that you don't have any fish with you.

CJ Doesn't Buy Sea Creatures

It's also worth noting that CJ will not take and buy Sea Creatures from you. The only way you can sell them is by bringing them in the Nook's Cranny.

No Sea Creature Models

Sea Creatures cannot be made into a model by CJ. They can only be placed on your island or added to the museum collection.
