When you find the above listed sea creatures you can deliver them to Blathers at the museum. This will send them to your fish section where you can see them at the bottom of the tanks. Collecting every single sea creature triggers a flavor text that says “I’ve completed my diving collection. That’s deep. Real deep.” There is no other reward for completion besides a few comments from Blathers when you hand in the final sea creature.
