It's been an interesting last.. Hmm? 40 years I would say, for the Sea Otter. Sea otters, are a
common animal most people hear about, but not many people actually know about. This is all
about a sea otters history, an ecosystem, and why they are in fact endangered. Sea otters however
have made a comeback and for the majority are not at risk anymore and aren't expected to be
anytime soon.
Sea otters are a very common yet diverse animal. They
are the only aquatic member of the weasel family. Since
the 1970's sea otters have become much more popular with
researchers and by entertaining people. There are 3 type of
recognized sea otters including the The Russian Northern
sea otter, The northern sea otter, and the southern sea otter.
Sea otters spend the majority of their time in the ocean but sometimes come ashore to rest.
They have water-repellent fur to keep their warm, webbed feet, and ears and nostrils that close
when in water. They're thick fur makes there body seem much thicker on land, than how it looks
in water. It also keeps them from possibly getting hypothermia from temperatures of water. They
have 600,000-700,000 hairs per square inch to make up for having no blubber. There are 3 type
of recognized sea otters including the The Russian Northern sea otter, The northern sea otter, and
the southern sea otter. Sea otters are in fact mammals. Adult (southern) sea otters can weigh
between 45-65 lbs and are some of the smallest marine mammals, considering they only grow to
4 feet. They spend a lot of their time grooming, cleaning, squeezing our water, and also blowing
on their fur. They do a lot of their work and foraging by sunrise, and usually are resting by mid- day. They are a threatene...

...w after the fur trade it's taken them about 200 years to slowly repopulate. They are
one of the most diverse species and lucky for Seagrass and kelp habitats, sea otters have been
making a big comeback. Cambria California has and will continue helping sea otters. Also, the
Canbria SMCA will continue so. And the biggest help of all is the Endangered Species Act. They
and the Sea Otter fund continue to help out the research and get contribution from taxes for The
Sea Otters. And they continue to not allow killing of sea otters and keep trying to restore their
health. Sea otters will continue to live happy lives repopulating and restoring. If you contribute
to the sea otter fund and pitch in to keep their continual protection, whether you believe it or not,
you too can make a different for these happy sea creatures, the amount of fish from kelp and
The guadalupe fur seals are valued for their fur and the oil that rendered from their blubber. They are brown with a mixture of gray with a hint of silver and yellow on the top of the neck. The males tend to be more of a deep brown and a light gray, and females are dark gray. Male guadalupe fur seals are much bigger in height and size compared to the females. The males weigh approximately 300 pounds and are 6 feet long. Females on the other hand, weigh up to 100 pounds and are only 4 feet long. All Guadalupe fur seals have long, narrow snouts, and they slightly up turn at the end, especially the

Save the World: Save the sea otters During the 18th and 19th centuries, sea otters were hunted for their luxurious pelts, and by the early 1900s, the species was believed to be extinct in California. (Carswell) Why do we care you ask, well not only are they super cute and eat with their hands. Apparently, a healthy population of sea otters keeps the sea urchin population in check. An unhealthy or small population of sea otters allows the sea urchin’s number to explode thus decimating kelp beds, which is the sea urchin’s food source, and causing a “chain reaction that depletes the food supply for other marine animals consequently causing their decline.
Bottle-nosed dolphins are generally coastal creatures, occurring along almost all tropical and temperate coasts, although offshore varieties also occur. In addition, the Bottle-nosed dolphin is called the "all-ocean" dolphin, meaning that it lives in every ocean. It is common for a school of 20 dolphins to live together in coastal regions, but school of 200 dolphins are found in the offshore verities. These schools do not seem to have a leader and generally stay together for life.
1 The sea otter is endangered because of oil spills in 1977. Tons of otters where hurt and were sent to the Marine Mammal. Under state law, southern sea otters are "fully protected" mammals. Southern Sea Otters are one of the smallest marine animals. Their fur is thick but soft when dry but in cold waters the thickness keeps them warm. The thing they eat are sea urchins, abalone, mussels, clams, crabs, snails and at least 40 other marine species. 2 Sea otters exhibit numerous adaptations which help them survive in their challenging marine environment. Long whiskers help them to detect vibrations in murky waters. Did you know that the sea otter is part of the weasel family and is the second biggest? Mating happens all throughout the year. Sea

sea otters are from the kingdom animalia. Sea otters are stouter and have large rib cages, smaller tails and muzzle than other species of otters. Yet sea otters posses the fine, dense fur coats characteristic of the Mustelidae. Their forefeet are small and dexterous with retractile claws and the flipper like hind feet are broad and webbed. Sea otters once was abundant along most coastal North pacific ocean. That was before fur traders hunted them for their thick ice, luxurious pelts. By the year 1900, sea otters were nearly extinct . Protected since 1911, alaska sea otters have made a comeback. There lifespan is 10-15 years. Great white sharks are the primary predator of sea otters and occasionally eaten by coyote so the predators that the
Humpback whales are amazing mammals and they go through a lot of extraordinary things to be able to survive. There are many whales in the ocean, but the whales that are in the Hawaiian culture areas have many difficulties and most people don't understand why.

In the world where people live in is an enormous responsibility but also the greatest gift that people need to cherish and protect. The human race needs to step up and voice not only their concerns, but the concerns of all the animals endangered or not. Any species which fall into the categories vulnerable, endangered, or critically endangered are considered to be at risk of extinction. {Robert Redford} said “I think the environment should be put in the category of our national security defense of our resource’s because it’s just as important as defense abroad otherwise what is there to defend?”
The polar bear is one the largest members of the bear family. Males Polar Bears stand from eight to 11 feet tall and generally weigh from 500 to 1,000 pounds, but can weigh as much as 1,400 pounds. Female bears generally stand eight feet tall and weigh 400 to 600 pounds, except some, which can reach 700 pounds. The reason the polar bear weighs so much is that is stores about a four-inch layer of fat to keep it warm.
