Otters will build their homes or Holt, around where there is a good supply of natural food such as fish, crustaceans and amphibians. Large entrance holes are normally found under the roots of old riverbank trees and there is usually plenty of reed and bramble cover around. A lot of holt's are now man made due to habitat loss and are made to encourage otters to a specific areas of conservation. Otters like locations that are not disturbed by human activities such as dog walking. A good indication of whether the holt is active, is a wet mud slide running down in to the water, depending on how high up the bank the holt is situated.

Why are sea otters called marine mammals?
Otters, seals, and sea lions are all mammals that nurse their young. Like penguins they live on land but feed at sea. They are also called "semi-aquatic" mammals to differentiate them from strictly sea species.
FOOD Otters are carnivores (meat eaters). They eat crustaceans (animals with shells), amphibians, reptiles, birds and insects, but mostly fish. They use their keen sense of touch to find and catch their underwater target. Their sensitive facial whiskers easily detect moving prey. This is especially useful in the murky water created by the otter searching for victims on muddy lake and stream bottoms. Otters typically hunt by diving and chasing fish, or by digging in the bottom of ponds and streams. Although otters are expert divers, hunting is not always successful. One study found that the success rate of finding food on a dive was less than 20%.
