Semi-Aquatic Mammals

well bevers have a very good sent so they can find thire mate.

i dont know dumo

Alligators don't get along with any other animal really. They'll eat an osprey if they can catch one...

yes they do , bears are apart of the dog family along the way. and when around all alone or scared they bark to be seen.

They paddle with 2 flippers that they have and I THINK THat The gills or the tail move themselve little, I dont know this is what my best friend told me ! So Look around a little because Im not that shhhuree!

Sincerly , Grazyson!

in the ice age the mammoths were the first elephants

Sea otters and seals do not necessarily like or dislike each other. Although they live in the same areas, they aren't natural enemies, and they don't have any relationship between the two species. You won't find them playing together, but to know whether they like each other is impossible (you can't read their minds to figure out whether they like each other the way that some people like animals).

I hope that answers your question.

platypus

Yes, homeothermic means warm blooded and all mammals are warm blooded (warm our bodies through food energy). Endothermic animals use the sun or other heat sources (such as reptiles)

For the typical mammals, the following properties apply:

1) hair on the body

2) endothermic regulation (warm-blooded)

3) milk-producing glands

4) live birth of babies (except egg-laying monotremes)

Yes, sea otters do, on their rear feet. They're very good swimmers & divers, quite interesting to watch them eating clams off their stomachs while floating. They use rocks to break open the shells. Their front feet (paws?) are very human-like in their dexterity & efficiency. They have opposing thumbs.

Sea Otters sleep in groups while wrapped in seaweed so they do not float away. The Alaskan Sea Otter will occasionally haul out on ice or rocks and sleep. It is very uncommon for California Sea Otters to haul out.

Sea otters were not invented.

No they do not. That's why they come up every once in a while.

Mammals are animals that MUST breathe air to survive. All otters areammals

It differs by where the otters are. But the predators are great white sharks, killer whales, and sea lions.

They are a vital part of the ocean's ecosystem. Without otters, sea urchins would have no predators and would overpopulate and likely destroy kelp forests, which are a food source for urchins.

Platypuses hide by digging burrows into a riverbank or creek bank. The entrance is usually disguised by overhang from the riverbank, or by tree roots and/or other vegetation. They are difficult to see, which is precisely what the platypus wants.

It has a marine biome or ecosystem.

Wetlands and marshes.

The giant otter eats piranas. I learned on the animal plantet. The giant otter is also indangered!

Yes it is! Mammals are warm-blooded animals, usually with fur or hair that produce milk to suckle their young, which are usually born live. One or two mammals lay eggs.
Yes an Otter is a mammal.

Sea otters are the only species in their genus, Enhydra. However, there are thirteen species of otter in the subfamily Lutrinae; these include the Marine otter, the North-American river otter, the Neotropical river otter, the Southern river otter, the Eurasian otter, the Hairy-nosed otter, the Asian small-clawed otter, the African clawless otter, the Congo clawless otter, the Giant otter, the Smooth-coated otter, the Spotted-necked otter, and (of course) the Sea otter.

nutria

Probably 6-7 per litter and it has 2-3 litters per year.

Sea lions and walruses are relatives of seals.
