Though hourglass dolphins are especially rare, they’re actually not a threatened or endangered species. This isn’t just luck, however, or some oversight of ecological research. Rather, it’s due to certain inherent traits of hourglass dolphins. For one, their habitat is the remote, cold Antarctic and sub-Antarctic waters.

An estimated 144,300 hourglass dolphins remain south of the Antarctic convergence. There are no direct threats to this species, largely because their remote habitat is rarely visited by humans. However, climate change could still pose a threat to hourglass dolphins in the near future.

The pattern creates the look of an hourglass.
