The Hawaiian monk seals are an endangered species of animals, endemic to Hawaii. Over the years they have been hunted and exploited by humans.

Climate change also contributes to a key reason because of which these animals suffer habitat loss with the sea level rising drastically. Males have been observed to show aggression at certain events towards the juveniles and females.

This is another key reason for the decrease in their numbers. The Hawaiian monk seal population continues to decrease at a rate of 4% every year.

These seals are usually smaller than the other varieties of seals and have a flat head and a short snout. They feed on fish, lobster, crustaceans, and octopuses.

They like to hunt their prey hiding under the rock or sandy beach in deep waters. One of the most unique features about these animals is that they can both sleep on beach and underwater caves.
