Video footage shot by a diver shows the danger to marine creatures from waste discarded by humans, in this case fishing equipment.

Raniero Borg, filmed a fishing trap dumped on the sea bottom, with a big octopus trapped inside it.

The trap door was bound with twine, with no way out for the octopus because the opening at the other end was too small. When Raniero opened the trap door, the octopus swam out and made off.

It is possible the octopus had entered through the opening and could not go out again, or else it could have entered when it was smaller and grew in size inside the trap.
