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.

Sea otters are endangered because of oil spills, habitation loss, food limitations, disease, fishing gear entrapment and conflict with shellfish fisheries
Hope that helps :)
Yes, many zoos have otters. Examples of zoos with otters are the National Zoo, San Diego Zoo, Minnesota Zoo, Philadelphia Zoo, the Trevor Zoo in Millbrook, NY, and the Trailside Zoo at Bear Mountain State Park in New York's Hudson Valley.
How many types of sea otters are there?
There are 13 different otter species and two varieties of sea otters.
What is the difference between an otter and a beaver?
Beavers have broad flat tails that they use to splash the water when they're in danger which alert other beavers about it. Otters's tail are rounded.
Yes Yes, the otter has hair, sweat glands, three middle ear bones, females have mammary glands and the otter has a neocortex region in the brain. These are all features of a mammal.
the biggest threat is running out of food and having humans killing them even when there's a law against hunting them.
Which animal is most closely related to the horse?
Horses and zebras are both equines. They are therefore related to asses, donkeys, onagers and mules (sterile hybrid of a horse and donkey).
A cross between a male zebra and a female horse is called a zorse.
Although an okapi looks a bit like a horse and a bit like a zebra, it is not related to either one. Its closest relative is the giraffe.
Orcas (killer whales) eat the sea otter which is partly why they are an endangered species.
What is odd about sea otter's spinal column?
Sea otter's spines are hyperflexible (or hypermobile), allowing them to bend in almost any direction and even into a complete circle. This attribute allows them to be able to reach every part of their bodies.
