Is the Asian small clawed otter a vertebrate?
Yes, it is a vertabrate.It has a backbone.Part of the back bone is what forms the tail.
Do otters us there tails to swim?
They use it to stabilize themselves when they swim and they use it to propel themselves for short distances while swimming.
How much sunlight do sea otters need?
It depends on where it is, but they are usually in shallow parts on water.
otters line near river, streams and oceans. so yes they swim.
How do otters take the meat out of an oyster?
They eat by first getting a clam or crayfish or whatever food is hard to open. They put the food they catch under their armpits then they grab a rock in the other hand. When the otter gets to the surface it'll lay on its back and lay the food on its stomach and hits the rock on the shell. Then the otter will have its food.
Why are giant otter's endangered?
It is native to South America but is endangered and is also very rare in captivity.
The Giant Otter can reach up to 6 ft (1.8 m) in length, and weigh 76 lb (34 kg) in weight.
The females are smaller and weigh only 57-60 lb (26-27 kg).
It has a lifespan of 12 years in their natural habitat, and 21 years in captivity.
Its fur is dense, thick and velvety, and is highly sought after by fur traders.

How do sea otters crack open hard shelled prey?
They float on their backs and lay the shell on their chest and hit it with a rock. (I wouldn't call it a prey but their food.)
Is a otter a herbivore or carnivore?
Carnivores -- they eat fish and small birds and mammals (if they can catch the birds and mammals). River otters also eat frogs, turtles and crayfish; sea otters also eat shellfish.
Otters are mammals like humans. And therefore, are born live. Reports on sea otter gestation range from four to nine months, with an average of six months. So, the answer to your question is no, an egg does not come out of an otter. a live otter is born from the mother.
No. An otter is a placental mammal. Marsupials give birth to undeveloped young, which must cling to the nipple for several weeks before they are developed enough to survive off it. Placental mammals give birth to much more developed young, and they only need to suckle some of the time.
What is the physical adaptation of a sea otter?
The Sea otter or Kalan (Enhydra lutris) is a large otter native to the North Pacific, from northern Japan and Kamchatka east across the Aleutian Islands south to California.
Generally sticking to shallow coastal waters of no more than about 55 meters in depth, sea otters are found most often in areas with rocky coastlines and thick kelp forests; barrier reefs and intertidal areas are also inhabited. These otters may be considered a keystone species; they control the population of certain invertebrates which would otherwise run amok if unchecked. Chief among these invertebrates are sea urchins and abalone, a favorite prey of the otters. To eat prey in shells they often use rocks, which sit on their stomach, to break open the shell in order to get the animal inside.
Crabs, mussels, scallops, cephalopods, fish, chiton, and snails are also prey to the sea otter. Individuals may show finicky preferences; despite this, they require 20-25% of their body weight in food each day, and they may forage for prey as often as every 5 hours. Their metabolism is higher than that of otters in captivity, and is 8 times the level in comparatively sized terrestrial mammals. Part of this may be because they have the lowest assimilation efficiency of carnivores (82%), and their gut transit time is only 3 hours. Also these small mammals lose heat easily to their aqueous environment because of water's high thermal conductivity. Sea otters consume more seawater than most other marine mammals. This is likely because of high urea production from a high protein diet, as well as their prey having a higher electrolyte composition than fish. Their kidneys are comparatively larger to other marine mammals in order to offset this.
