The remora can grow up to nearly 3.3 feet in length, but its most common size is around 16 inches. It can weigh over 2.2 pounds. The remora has a long, slender body with a very distinctive feature running along its entire length and a fan-shaped tail. The remora is typically gray to dark brown in color.

The remora enjoys company, however, it sometimes swims alone near coral reefs !

The remora has an oval-shaped suction cup

The remora has an oval-shaped suction cup. As it grows, its first dorsal fin gradually transforms into a suction cup. It is thanks to this suction cup that the remora most often attaches itself to sharks, but also to large fish, rays, cetaceans, sea turtles, boats, and even divers. However, it sometimes swims alone near coral reefs.

Geographic range

The remora is found in tropical and subtropical waters as well as in temperate waters around the world.

Habitat

The remora is found from the surface down to about 328 feet in depth. The remora visits the same areas as its host with which it travels.

Diet

Tips for observing

The common sea fan

The common sea fan, is a type of soft coral found in the warm, shallow waters of the Caribbean and the western Atlantic ocean. It grows in wide, fan-shaped forms that sway gently with the ocean currents, helping it catch tiny food particles drifting by. Its beautiful purple branches are covered by a thin living tissue that hosts tiny algae, which provide much of the coral's energy through sunlight.
