The conger eel favours man made structures which are littered along the coast either accidentally or deliberately to become part of the seascape. They can be found in rock crevices and in ship wrecks along with other animals, for example, lobsters and crabs. Sand eels Another eel typically found around Britain is the sand eel. They inhabit extremely exposed regions and compensate for this by being able to burrow in sandy substrates to avoid predators. They also bury at night and when the tide recedes.
Sand eels prefer clean fine sand which permits a quick retreat from predators.
Sand eels feed on small fish and crustaceans and are predated by seals, herring, mackerel and many sea birds.
