Animal Crossing: New Horizons has just received its July update, and it's a biggie. Not only has this update generously added swimming and diving, but a whole host of new sea creatures to find and collect in addition to everything else.

If you're like me and can't resist hunting down critters and taking them all to Blathers, then this is the update you've been waiting for. All you need to do is don your swimming costume, and head down to the beach.

If you need more information on what you need to do once you get to the beach, we have a guide for that, but many of you will just need to know what's available, and when, and this is where our guide of all the sea creatures in Animal Crossing: New Horizons comes in.

Here you will find every single sea creature listed, with the most up-to-date information we have. There are so many sea creatures that we haven't been able to find them all ourselves, and so this guide was created with some information from the Animal Crossing Fandom. This list will be updated to have all of the gaps filled soon, so keep checking back if you need to know something specific!
