Veined Octopus or Coconut Octopus Amphioctopus marginatus (ex. Octopus marginatus) occurs in temperate and tropical waters of the Indo-West Pacific in a depth range from 0 to 190 m, max. length 30cm, mantle length 10cm, max. weigth 400g. The Veined Octopus can bury itself in sand or mud. They also exhibit a curious behaviour adaption of using discarded clam shells and halves of coconut shells for protection. Sandy and muddy habitats the octopus inhabits leave itself little protection from passing predators. Discarded halves of coconut shells are common in waters near human settlements throughout Indonesia. When two halves fit together, the halves make a perfect refuge difficult for predators to open. Amphioctopus marginatus lays up to 100 000 small eggs which hatch into tiny planktonic young. These young are carried in ocean currents, accounting for its wide distribution. This specimen was encountered walking around with a bivalve shell. Lembeh Strait, Indonesia 1°29'33.414 N 125°15'40.446 E at 18m depth
