They have small mouths and humped backs. Their pelvic fins are modified into an adhesive, sucking disc between their pectoral fins. Colour ranges from blue or grey-blue to greenish brown. ReproductionSpawning takes place in shallow inshore waters, in late spring. A female weighing 1 kg lays 140,000 eggs. The male guards, fans and puffs water over the eggs. DietThey feed on small fish and a wide variety of invertebrates, such as small shrimp, worms and jellyfish. PredatorsLumpfish are eaten by such marine mammals as seals and whales, and by sharks. HabitatThey live in deep, cold water offshore. As adults, they remain mostly on rocky or pebble bottoms. The young are semi-pelagic, i.e. they can live either on the bottom or in deep water. Lumpfish often hide under floating algae. Ecology, behaviourThis is a slow, inactive fish. It can attach itself to rocks or floating algae with its sucker.
