Crab names can be as diverse as the many varieties of this unique marine creature. Inspiration for naming a pet crab can come from their crustacean characteristics or your pet’s particular personality. We’ve chosen names suitable for some of the most popular pet crab species, plus a range of cool, funny, and type or breed specific crab names too. From the horseshoe to the rainbow crab, we’ve got you covered!


There are over 6,000 species of crabs found around the world in a wide range of colors and sizes. Many crab varieties can survive on land and in the water because they have gills and lungs. Although not your average pet, crabs do make terrific low-maintenance companions. They never need walking or grooming, don’t take up much space, and won’t eat a lot either.

Boy Crab Names

Male crabs are called jimmies; females are sooks. You can tell the gender of your pet crab by looking where the rear legs meet the body. If there are two black dots, it’s a female, and no dots means it’s a boy. Choosing a traditional human name is always a good option when naming a pet.
