Underwater male and female Cuttlefish (Sepia pharaonis) Cephalopod laying eggs - Vídeo de stock

Coral reefs are the one of earths most complex ecosystems, containing over 800 species of corals and one million animal and plant species. Here we see a shallow coral reef with two Pharoah Cuttlefish (Sepia pharaonis). Having recently mated, the female is laying her eggs. Cuttlefish (Cephalopod) are able to produce eggs several hours after fertilisation. The male guards her as seen here. This is a primal instinctive animal behaviour, that helps to ensure their survival. Image taken whilst scuba diving in Phi Phi archipelago, Krabi, Thailand.
