How to Find Sea Creatures

Dive by Bubbles and Shadows

Enlarge Sea Creature Bubbles

Enlarge Sea Creature Shadow

To find Sea Creatures, you'll first have to find bubbles and shadows while swimming. Once you've found them, dive with the Y Button to try and catch it.

To Swim, you also need to prepare a wet suit!

Swimming and Diving

Best to Dive When On Top of Bubbles

Because of the 10-second underwater limit, the best strategy for catching sea creatures is by diving when you're right on top or near the bubbles.

While you're underwater, you don't need to press anything to catch a sea creature. Just get near the sea creature's shadow, and you will automatically catch it!

What Can You Do with Sea Creatures?

Donate Sea Creatures to the Museum

The first time you donate sea creatures to Blathers at the Museum, you will see an option saying "I found a sea creature!" above "Make a donation."

Choose that new option and you will be able to donate only 1 sea creature. After donating that first sea creature, the "I found a sea creature!" option will no longer appear, you can return to choosing "Make a donation", to donate multiple sea creatures (fish, bugs, fossils, and artwork) at a time.

How to Unlock and Upgrade the Museum

Sell Them at Nook's Cranny

Any Sea Creatures you don't need, you can sell at Nook's Cranny for Bells. Currently, the Gigas Giant Clam has the highest sell price, at 15,000 bells!
