6. Sea otters have the thickest fur of any animal. Their fur includes between 600,000 to one million hair follicles consistent with square inch. not like maximum other marine mammals, otters lack a blubber layer. alternatively they depend upon their dense, 7729ed14a4cbb62c88851c47b865930b fur to offer insulation. To hold heat, sea otters spend a large component of their days grooming and conditioning their fur. This traps air and heat next to their pores and skin.
Tail
The tails of river otters and clawless otters are long, and approximately one-0.33 of general body duration. they're thick at the base, muscular, flexible, and taper to a point. The large otter's tail is just like the ones of other freshwater otters. but rather than tapering to some extent it becomes lance-fashioned - flattened top-to-bottom, with a important flange on each aspect. A freshwater otter uses its tail to propel itself when swimming at high velocity, to persuade whilst swimming slowly, and to help stability while standing upright on its hind legs.Compared to other otters, sea otters have shorter and less muscular tails, without a marked tapering. at the same time as floating on its back, a sea otter can scull with its tail to turn.Like most different mustelids, freshwater otters have subcutaneous anal scent glands at the base of the tail. Sea otters lack fragrance glands.
Head
Otters have flattened heads and brief, thick necks. A sea otter has a blunter muzzle than those of other otters. Eyes are located towards the front of the pinnacle. Ears are very small, and either rounded or pointed. The valve-like shape of the ears allows them to shut while inside the water.The nostril pads of otters vary notably with the species.The nostril pads of maximum otters are flat and bare with some variant on a spade or anvil form. Most river otters have black nostril pads. The smooth otter and clawless otters have nostril pads which can be dusky or pinkish in coloration. The nose pads of bushy-nosed and giant otters are partially or completely blanketed with hair.
A sea otter's nostril pad is big, naked, black, and diamond-formed. An adult female's nose pad often bears crimson scars from wounds inflicted at some stage in mating, whilst the male grasps her nostril together with his enamel. Just like the ears, an otter's nostrils close whilst under water.
Enamel vary with
diets.
Fish-ingesting otters that seize prey with their mouths have sharp teeth. Shellfish-eaters have more blunt teeth, adapted for crushing shells.
Sea otters have 32 enamel, on the whole put up-canine molars. they may be designed for crushing and grinding the shells of invertebrates, now not for tearing flesh. Sea otters are the handiest carnivores with just pairs of incisors in the lower jaw. Their incisors appear to function in scraping the gentle parts of molluscs from
Vibrissae.
An otter is prepared with vibrissae (whiskers) on its muzzle. Vibrissae are sensitive to the touch and to underwater vibrations. Otters use their vibrissae to discover the moves of prey.
