It's unclear how long the fish had been stuck there with his friend holding vigil, though he stood little chance of surviving for long in those binds. Fortunately the snorkeler, a volunteer from the marine conservation group Core Sea, had found them in time.
With no other tool handy, the man used a shard of broken glass to carefully cut the pufferfish free. All the while, even in light of the potential threat the snorkeler posed, his companion remained.
As touching as this show of pufferfish solidarity is, it might not actually be uncommon. Despite long-held beliefs that fish are generally devoid of feeling or intelligence, a recent study found these animals are in fact smarter and more social than most folks ever realized. And because of that, it might be time we reconsider how we think of them.
