How much does a Marine otter weight?

It is hard to guess what a Marine otter weights. But we have the answer:

An adult Marine otter (Lontra felina) on average weights 11.2 kg (24.69 lbs).

The Marine otter is from the family Mustelidae (genus: Lontra). When reaching adult age, they grow up to 67.8 cm (2′ 3″). Usually, Marine otters have 2 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 average adult weight of a Marine otter is 11.2 kg (24.69 lbs)

The marine otter (Lontra felina) is a rare and relatively unknown South American mammal of the weasel family (Mustelidae). The scientific name means “otter cat”, and in Spanish, the marine otter is also often referred to as gato marino: “marine cat”. The marine otter (while spending much of its time out of the water) only lives in saltwater, coastal environments and rarely ventures into freshwater or estuarine habitats. This saltwater exclusivity is unlike most other otter species, except for the almost fully aquatic sea otter (Enhydra lutris) of the north Pacific.
