During an expedition, a scuba diver saw an animal use stinging tentacles to capture and eat its prey. Whatanimal did the diver see?

My answer is an octopus.

There were three possible answers for this question but I think the correct answer is an octopus. The octopus uses its tentacle to catch their prey. It often injects a poison inside their prey in order to kill them while slowly pushing their prey into their beak.
