Hawaiian Monk Seal Facts | Hawaiian Monk Seal Habitat & Diet

I’ll be displaying some of the most significant Hawaiian monk seal facts including monk seal diet, habitat, and reproduction. The Hawaiian monk seal (Monachus schauinslandi) is a species of earless seal that belongs to the family of Phocidae. The monk seal is an endangered species and it inhabits in the Hawaiian Islands. These animals are solitary animals like certain monks. The other monk seal species is Mediterranean monk seal. This is the only extant seal species endemic to Hawaii. A small number of seals estimating 1,100 are threatened because of illegal human encroachment. The evolutionary history of Hawaiian monk seal is still under discussion as scientists have not been able to discover enough fossil’s evidence to figure out the precise ancestors of these species. Nevertheless, these seals are regarded as the most prehistoric of extant seals that evolves from the Caribbean species M. tropicalis.

The mother will nurse its pups for about 6 weeks during this period the mother won’t take any meal whatsoever and thus it will lose its weight considerably.

A good many number of these species are also found on Peal and Hermes Atoll, Layson, Midway, and French Frigate Shoals. The Hawaiian monk seals are listed as critically endangered species.
