Among many
ocean creatures who perform cleaning services, one is the remora, or suckerfish. This bold fish travels with the shark, one of the most feared ocean
predators. The remora has a large sucker on top of its head with which it
attaches itself firmly to the shark. (Some remoras attach themselves to other
large ocean creatures, even whales.) As the shark swims along, the remora
travels all over its body removing debris. It gets food
and protection - and an occasional feast. Sharks are messy eaters, and when the
shark feeds, the remora detaches itself and gobbles up the leftover bits. (Adapted
