With a total of 40 sea creatures to collect in Animal Crossing: New Horizons, finding all of them is no small task. Additionally, different creatures will appear depending on the month, season, and time of day you’re playing the game.
In this guide, we’ll show you how to find every sea creature in ACNH by highlighting their location, shadow size, movement speed, and the time of day they appear. We’re also including the selling price for each creature in case you’re looking to earn Bells quickly in New Horizons.

How To Catch Sea Creatures
To catch the sea creatures that live at the bottom of your island’s oceans, you’ll have to get into the water and dive down to find them. To do this, you’ll want to first make sure you have the most recent update, which should be version 1.3.0 or higher.
This update adds the wet suit (required for diving), sea creatures, and other new features to New Horizons. Once your game is updated, you should be able to purchase a wet suit from Nook’s Cranny for 3,000 Bells and use it for diving. For a more detailed breakdown, read our full guide on how to get a wet suit and swim in ACNH.
After equipping a wet suit, head into the water by pressing A while facing the ocean or jump off one of your island’s docks. While in the water, you can press A and use the left analog stick to swim in any direction. As you explore, you will start to see shadows accompanied by bubbles coming from the ocean’s floor.
Once you’ve identified a sea creature’s shadow, dive underwater by pressing Y and make your way towards them. Some animals may try to escape, requiring you to chase them down. Once you’re close enough to the shadow, your character will automatically catch the creature and return to the surface.

What To Do With Sea Creatures You Catch
Any sea creatures you catch can either be donated to the museum or sold for Bells in Nook’s Cranny. Depending on the rarity and selling price of the creature, you may want to prioritize one option over the other.
To make a donation, you’ll first have to unlock and then upgrade the museum by speaking to Blathers. Every time you donate a specimen, Blathers will offer to tell you a bit about the creature’s history before putting it on display in the museum.
To sell a creature to Nook’s Cranny, approach Timmy or Tommy like you would to sell any other item. Avoid using the drop box outside to sell critters, since it offers a lower amount of Bells than the standard selling price.
Remember that any Scallops you find can be exchanged for unique rewards by talking to Pascal, the red otter who sometimes appears in your island’s oceans.
Lastly, since Pearls don’t count as sea creatures and can’t be donated to the museum, you can either sell any you find for a cool 10,000 Bells each, or hold onto them if you plan on crafting the mermaid furniture set.
