The octopus can have a mantle length of over 20 cm and a corresponding weight of nearly 10 kg, but common size and weight are much smaller. As the name implies, it has eight tentacles. Each is lined with a twin row of suckers. The octopus passes the winter in deep water but approaches the coast in the early spring and passes the summer in inshore waters. It hunts by night, voraciously, but itself falls prey to the conger and moray eels.
