Their body is perfectly adapted to the aquatic environment in which they live.
The body is long, with aerodynamic shape.
The long tail is thick at the base and is tapering towards the top.
The coat is thick with large, stiff bristles, under which lies soft, short fuzz, that ensures impermeability and buoyancy.
The back is chestnut-colored, lighter on the belly.
The fingers have claws joined by a membrane.
The limbs, short in relation to the body, are perfectly suited to the functions they perform: the forelegs are used to dig and swim, the back legs just to swim.
On land, otters lumbered through jumps.
Equally, smell, sight and hearing are highly developed.
The eyes are small and lively, teeth are very sharped and the ears are small.
Small ears are adapted to aquatic life and are provided with two folds that cover the ear when the otter enter the water.
Otter is a twilight and night animal. Rarely, it can be seen during the day.
Length: approximately 1 m (tail included).
Height: 30 cm.
Weight: up to 10 kg.
Diet: otters eat mostly fish (trout, grayling, carp) and sometimes crayfish, frogs and other small aquatic mammals. In some cases, otter can remain submerged up to 7 minutes.
Because food consists mainly of fish, otter represents a real danger to puddles and ponds. The otter is moving easily from one water basin to another, only to search for food.
The otter doesn’t build its own gallery, but it’s using the foxes or badgers galleries? The gallery of an otter has both an aquaticand a terrestrial entry.
The otter lives solitary? After birth, the female remains only half a year with her puppies.
