A marine biologist is someone who studies, or works with, a salt water organism. That's a very general definition. With the oceans covering over 70% of the Earth’s surface and providing habitat for thousands of species, marine biology is a very broad field - and being a marine biologist doesn't just mean being a dolphin trainer.

Gastropods are a group of animals that includes snails, slugs, limpets and sea hares. Many gastropods have a visible shell, although some, like slugs and sea hares, have no shell, or a small, internal remnant of a shell. In gastropods with shells, many are spiraled or coiled, like in the triton shown here.
Speaking of coils, a hint to the Guess the Creature image posted recently is that it is something made by a gastropod. Do you know what it is?
Gastropods move using a muscular foot. With thousands of species of gastropods on the planet, these animals can be found just about everywhere on Earth - both salt and freshwater, and on land.
Do you have a favorite gastropod species?
