Report Abuse. This isn't quite exact, but 1/4 cup of butter (so a half stick if you're in the US) is 57 grams according to the conversion chart from allrecipes below. So use just a slightly heavy 1/4 cup or 1/2 stick. By the way, a 1/4 cup is 4 Tablespoons.
Normally, this species is 57 to 95 cm (23â37 in) long, not counting a tail of 35â45 cm (14â18 in). The female is shorter than the male. The otter's average body weight is 7 to 12 kg (15.4â26.4 lbs), although occasionally a large old male may reach up to 17 kg (37 lbs). The record-sized specimen, reported by a reliable source but not verified, weighed over 24 kg (53 lbs).
Many adult marine mammals gain and lose weight throughout the year depending on the water temperature, food availability and behavioral changes associated with breeding seasons. Here at the Seattle Aquarium we weigh our marine mammals at least twice a month in order to monitor their health. Unlike other marine mammals, sea otters do not have an insulating layer of blubber and instead rely on their dense fur and high metabolism to keep warm. Sea otter fur is the densest of any animal on earth with an average of 500,000 hairs per square inch. They live in water that ranges in temperature from 35-60Â°F, so in order to keep their body temperature at approximately 100Â°F, a sea otter needs to east approximately 25% of its body weight each day!
