Remora are small fish that live in all tropical seas.  Sometimes called shark suckers, these remarkable fish are known as the “hitchhikers” of the sea, for they attach themselves to larger fish for transportation about the ocean.

The remora has an odd sucking disc on the top of its head that looks like the sole of a rubber shoe, with which the remora attaches itself to whales, sea turtles, sharks and large fish.

When the bigger fish feeds, the remora eats the bits of food that falls from its host’s mouth.  Sometimes several remoras will hitch a ride on the same fish.

If the remora has hitchhiked into the area of a school of small fish, it detaches  itself and swims after its own food.

After it has eaten its fill, the remora looks for another large fish to hitch a ride to its next meal.

In some parts of the tropics fishermen use the remoras in fishing.  The fisherman fastens a line to the remora’s fall and allows it to swim about.  When a large fish swims near, the remora promptly attaches itself to the larger fish.  Then both can be pulled in. – Dick Rogers
