It is sometimes mistaken for a Dall's porpoise, but it is actually a Pacific white-sided dolphin, with a dorsal fin that resembles the blade of a sickle.

Dolphins are classified as smaller than 4 meters in length, while whales are classified as larger.
However, there are exceptions and there is no clear standard.

Hermit crabs that live on land have remnants from when they were in the water, and breathe through their gills and abdominal skin. They can only breathe in moist places.

Because they have a lot of fat, they are able to maintain their body temperature.

The snake produces secretion to facilitate molting. The eyes appear white because the secretion is white.
