About Fundulus majalis (Walbaum, 1792)
The striped killifish, whose scientific name is Fundulus majalis, is also commonly called the striped mummichog. It is a North American fundulid killifish species. It inhabits saltwater and brackish shallow coastal areas ranging from New Hampshire to Florida, and also lives in the northern Gulf of Mexico. This species shows clear sexual dimorphism: males have vertical black stripes, while mature females have horizontal black stripes running along the sides of their silver-colored bodies. Juvenile females have vertical stripes, and adult females still retain one or two vertical stripes at the tip of their tails. Most striped killifish grow up to 6 inches, or 15 centimeters, in length, though individuals may occasionally reach 7 inches, or 18 centimeters.
