what is the average size of a sea otter
Sea otter The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean. Adult sea otters typically weigh between 14 and 45 kg (31 and 99 lb), making them the heaviest members of the weasel family, but among the smallest marine mammals. Unlike most marine mammals, the sea otter's primary form of insulation is an exceptionally thick coat of fur, the densest in the animal kingdom. Although it can walk on land, the sea otter is capable of living exclusively in the ocean.
Jack Russell Terrier The Jack Russell should always appear balanced and alert.[32] As it is primarily a working terrier, its most important physical characteristic is its chest size, which must not be so large that it prevents the dog from entering and working in burrows.[16] The red fox is the traditional quarry of the Jack Russell terrier, so the working Jack Russell must be small enough to pursue it. Red foxes vary in size, but across the world, they average from 13–17 pounds (5.9–7.7 kg) in weight and have an average chest size of 12–14 inches (30–36 cm) at the widest part.[34]
