How much does a Hawaiian monk seal weight?

It is hard to guess what a Hawaiian monk seal weights. But we have the answer:

An adult Hawaiian monk seal (Monachus schauinslandi) on average weights 223 kg (491.63 lbs).

The Hawaiian monk seal is from the family Phocidae (genus: Monachus). It is usually born with about 16.28 kg (35.88 lbs). They can live for up to 30 years. When reaching adult age, they grow up to 2.24 meter (7′ 5″). Usually, Hawaiian monk seals have 1 babies per litter.

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

The Hawaiian monk seal (Neomonachus schauinslandi, formerly Monachus schauinslandi), is an endangered species of earless seal in the family Phocidae that is endemic to the Hawaiian Islands.The Hawaiian monk seal is one of two remaining monk seal species; the other is the Mediterranean monk seal. A third species, the Caribbean monk seal, is extinct.The Hawaiian monk seal is the only seal native to Hawaii, and, along with the Hawaiian hoary bat, is one of only two mammals endemic to the islands.These monk seals are a conservation reliant endangered species. The small population of about 1,400 individuals is threatened by human encroachment, very low levels of genetic variation, entanglement in fishing nets, marine debris, disease, and past commercial hunting for skins. There are many methods of conservation biology when it comes to endangered species; translocation, captive care, habitat cleanup, and educating the public about the Hawaiian monk seal are some of the methods that can be employed.
