Arabian Gulf sea snake (Hydrophis lapemoides)
Still very much alive! This is what the ARKive website has to say: Prey is caught by means of a swift bite, administering a highly toxic, fast-acting venom, which kills the victim and also breaks down its tissues to aid digestion. Despite the venom being highly toxic to humans, sea snakes are usually placid and present little threat.
Fish traps (gargoor) Traditionally made from palmbranches, these 'modern' ones are made from wire.
and of course a walk on the beach wouldn't be complete without a collection of shells...
