List of sea creatures in New Horizons
The following is a list of sea creatures in Animal Crossing: New Horizons. While initially absent from Animal Crossing: New Horizons, sea creatures were added in the 1.3.0 Free Summer Update (Wave 1).
The total number of sea creatures in New Horizons is 40, 10 more than the number of sea creatures in Animal Crossing: New Leaf. Sea creatures that have been removed since New Leaf include the Clam, Ear Shell, and Horsehair Crab. Creatures new in New Horizons include the Dungeness Crab, Firefly Squid, Gazami Crab, Gigas Giant Clam, Moon Jellyfish, Mussel, Sea Pig, Sea Pineapple, Slate Pencil Urchin, Umbrella Octopus, Vampire Squid, Venus' Flower Basket, and Whelk.
Some sea creatures will not spawn in the game until the player has caught a specific total amount of sea creatures. For example, some of the more lucrative sea creatures like the Red King Crab will not spawn until the player has caught at least 80 sea creatures in total.
