This name generator will generate 10 random names fit for all sorts of aquatic mammals, like seals, dolphins and whales, but many names will also work for (larger) fish, like sharks.
Technically animals like polar bears and otters are marine mammals as well, but there are other pet name generators which will fit those species better in most cases.
There's a large variety of names available ranging from cute and cuddly to strong and fierce, but if you're still stuck for inspiration try out some of the other pet name generators (links at the bottom of this page). You'll find many names work for many different animals.
