A total of 40 sea creatures can be found at different times of the year. They have their own Critterpedia page, and you can donate them to Blathers just like fish, bugs, fossils and art in order to fill the Museum's collection.
Sea creatures can also be sold for Bells at Nook's Cranny. They are pretty profitable as their sale price starts at 500 Bells (sea anemone, sea cucumber, sea star) and can go as high as 15000 Bells (gigas giant clam). Refrain from using the store's drop-off box where every item in the game sells for 20% less.
Also, the fact that they're found continuously in the sea and that you can stay in the water as long as you want (unlike tools that break, your wet suit won't), makes them a constant source of income.
Learn how to catch them here or scroll down to check all sea creatures' prices in a sortable list!
Click on the up & down arrows in the table to sort the sea creatures by price (Nook's Cranny regular prices and lesser drop-off box prices) or alphabetically (by name, subcategory or particularity).
Clicking once sorts the chosen column in ascending order — from the lowest to the highest price or from A to Z. The second click sorts its items in descending order — from the most expensive to the cheapest or from Z to A.
Please note: All prices are in Bells.
