The biggest addition to part one of Animal Crossing: New Horizons' summer update is the ability to swim and dive in the ocean around your island, which means new creatures to catch. In fact, wave one of the summer update added an entirely new category in your Critterpedia, titled "Sea Creatures," and Blathers is accepting donations of new finds at the museum as well. There are 40 total new sea creatures to catch.

Here we'll go over every new type of sea creature you can find while diving. If you don't know how to dive yet, check out our guide on how to swim in Animal Crossing for info on where to get a wet suit and how to get into the water for the first time.

How To Find Sea Creatures In Animal Crossing

Sea creatures can only be found while diving underwater in the ocean. You'll know you're near one when you see a column of bubbles floating to the surface, or when you're already underwater and spot a dark shadow beneath the waves. Just dive under and swim over to the shadow to automatically collect the creature. Sometimes the shadow might be moving, so you will have to follow or chase it.
