Because all species of otter naturally have relatively low birthrates, combined with their 15-year average lifespan, they are vulnerable to extinction factors. These threats include hunting for the fur trade (a practice that has widely been abolished), oil spills, and imbalance in the food chain. (Orca whales, for example, are growing stronger populations, where some fish, such as salmon, have become increasingly threatened.)
Its becoming extinct because people are killing them and ruining their homes.
no
Sea otters are under threat from pollution (particularly in the form of oil spills), changes/imbalances in the food chain, and the lingering threat of the fur trade, among other factors.
The Stellar sea lion, an eared seal, sometimes feeds on otters.
set up breeding centres like China does for pandas
yes, sea otters have young sea otters called pups
a sea otters habitat is the sea
Sea otters were not invented.
a sea otters habitat is the sea
where do sea otters rest
Sea otters are secondary consumers. This because sea urchins are primary and sea otters eat sea urchins.
yes they do live in the sea that's why they are called sea otters.
No, mule deer are not threatened by extinction, if that's what you mean by are mule threatened. If you mean are mule deer threatened by other animals, then yes, they are threatened by other animals. They are threatened by their predators, such as cougars and coyotes, but not by extinction.
