Did You Know?
The Hawaiian Monk Seal is one of the most endangered marine mammals in the world.
They are found only in the Hawaiian Islands.
Unlike most seals, Hawaiian Monk Seals spend a lot of time resting on sandy beaches.
They can hold their breath for up to 20 minutes and dive to depths of over 1,600 feet to hunt for fish, octopus, and lobster.
Sadly, their population is declining due to threats like habitat loss, food limitations, and human interaction.
Hawaiian Monk Seals are named for their short hairs, which resemble a monk's cowl, and their solitary nature.
Pups are born with a black coat and shed it after about 3-5 weeks to reveal their gray fur.
