 HAWAIIAN MONK SEAL

Endemic to Hawaii; a federally endangered species.  Only 1200 individuals remain, mostly at the uninhabited Northwestern Hawaiian Islands.  Some individuals visit beaches in the main Hawaiian Islands and must be observed from at least 100 feet unless the animal comes toward you while you are in the water.  Do not attempt to approach, pursue, or touch, as it is illegal and they can bite.  For more information about Monk Seals


CETACEANS

Whales

Order Mysticeti

Baleen Whales

Baleen whales have jaws with many stiff plates used to strain small food items from mouthfuls of seawater.  They also have a pair of blowholes and communicate using sound.  Baleen whales do not possess the ability to use sound for navigation (echolaction).

HUMPBACK WHALE

The North Pacific population spends winter in Hawaii, Japan, or Mexico for mating/calving before returning to feed upon small fishes and crustaceans.  Only males 'sing' during the mating season, the same song is used by the entire group while the arrangement evolves from year to year.


Order Odontoceti

Toothed Whales

Toothed whales include dolphins, porpoises, sperm, and beaked whales.  They have a single blowhole, conical teeth, and use sounds for echolocation and communication.  Most are not endangered species but are protected by federal law.  Dolphins are wild animals and should be treated with respect for your safety.
