Mammals

Kier whale trainers earn a very low wage considering what they do. It's roughly $40,000 a year. To become an animal trainer you have to be 18 years of age and have previous animal experience (large mammals or livestock preferably). You need to be able to speak confidently to the public and have good dance and drama skills. You need to be SCUBA and CPR certified. You need to have a university degree in animal behaviour, psychology or zoology. Swimming skills are the main part of the interview process. The swim test includes a 200 ft. freestyle swim, an 100 ft. underwater swim and a free dive to the bottom of a 26 ft. Your physical health needs to be top form and you need to be able to life 50 lbs. Trainers typically work 8 hours a day but sometimes more if necessary. The job isn't all glamourous. 70% of the work is cleaning the pools, toys, buckets etc. etc. 10% is a 30 minute fitness session, 5 days of the week. So only 20% of the works is with the animals. Also remember that killer whale trainers don't get time off work. It's very hard to get time off since it's important you're with the animals all the time. The components of an average day are divided into the various sessions with the animals which are: learning, relationship, exercise, play, and shows. The number and frequency of these sessions vary each day to create an enriching and stimulating environment for the animals - they never know what is going to happen next. Along with these sessions are the other duties like food preparation and distribution, assisting veterinarians with medical examinations, keeping the animal habitats clean and safe, observing the animals and documenting behavior and maintaining the health and diet records. Sometimes trainers may travel to the other parks and to meetings and conferences, but it is not a large component of the position. An animal trainer's job is one of the most visible and desired jobs in a zoological park, it is also one of the most rigorous. Trainers must perform in front of large audiences, being entertaining and enthusiastic each time. They spend many hours in 55°F water and free dive regularly to 35 feet (10.7 m), they lift and move 50 lb (22.7 kg) buckets throughout the day. They must also be patient and consistent when working with the animals. They can be scheduled to work at any time and day of the week and they work outdoors in all types of weather.

Most mammals are capable of swimming. The ones that spend all of their time in water are called aquatic mammals, and the ones that spend part of their time in water (such as platypuses, otters and beavers) are called semi-aquatic.

Doesn't have one. Montana has a state animal which is the Grizzly Bear.

Balaenoptera musculus (the blue whale) is said to be the largest marine mammal in the world, reaching 33 metres of lenght and 180 tonnes of weight.

Monotremes lay eggs, as do reptiles.

Monotremes' limbs go outward (rather than downward) from their main body, which is also true for reptiles.

Monotremes lack a corpus callosum (which placental mammals have), as do reptiles.

Monotremes and reptiles both have cloacas, while placental mammals have separate openings for urination and defecation.

This evidence all shows monotremes to be a link between reptiles and mammals, but we now think that monotremes just evolved from an earlier branching from the mammalian tree of lineage than the marsupials and placental mammals evolved from. Monotremes are not a link between reptiles and mammals.

This question has absolutely not merit. A black bear is a mammal regardless which state it is in or on or whatever.

I was traveling betwee Sullivan Missouri and Cuba Missouri a few weeks ago along I44 and I saw a porcupine dead along the road. I questioned my vision and traveled back along the service road and sure enough it was a pocupine. Hope this helps.

in 1997 the first Transgenic cow was Rosie,who produced human protein-enriched milk at (2.4 grams per litre).The milk contained the human protein alpha lactalbumin.

Whales are mammals and must breathe air to survive but , unlike humans and other mammals, they are 'voluntary breathers', which means they must physically remember to go to the surface and breathe! Depending on the species of whale, lung capacity differs. But, they all return to the surface of the water, open a blowhole on the top of their heads (a watertight valve) to expel air and quickly take in more before going down below the water's surface.

How do whales stay under water for an hour or more on a lungful of air?

The answer is: they do not. Whales expel the air from their lungs shortly after diving so they are no longer buoyant. The rest is squeezed out by increasing water pressure. They are able to remain under for so long by oxygenating their blood because of their increased lung capacity.

When a whale dives oxygen is only sent to the parks of their body's that need it the most like the brain Muscles for swimming and their heart, the rest of the body must wait for the dive to Finnish until it can get its oxygen, unless the dive is a very long one so the animal gives the other parts of its body like the stomach a little bit of oxygen every 20 minutes or so.

Human beings can hold their breath under water for an average of one minute. A hippopotamus can stay underwater for 15 minutes. The sperm whale and bottlenose whale can stay underwater the longest: some have been recorded on dives that lasted nearly two hours.

The best evidence for the existence of dinosaurs are thousands of fossilized dinosaur skeletons of hundreds of dinosaur species. There are also fossil footprints, skin impressions, and, in a few rare cases, dinosaurs mummified and fossilized, preserving skin.

Most terrestrial animals dissipate excess heat by evaporation. This is done by either sweating (like humans) or by panting (like dogs).

Marsupials have baby pouches. Kangaroos, wallabies, possums, and some others.

No. It has feathers so it's not a reptile.

Actually, not all animals that lay eggs are mammals, and not all mammals give live birth. Some snakes have livebirth(reptile), and the platapus(mammal), lays eggs. But, to answer your question, animal that lay eggs are called reptiles, amphibeans, fish, and birds.

Mammals proliferated during the Cenozoic (recent age--since the end of the Cretaceous 65 million years ago). There were mammals before the Cenozoic, but dinosaurs were the most abundant fauna of that era. Reptiles, birds, fish, and turtles continue to exist. There are over 8000 species of birds, but fewer than 6000 species of mammals.

Same way you do people, smash food up to a point where they can eat it

A mammal mother that has her babies nearly one third of her own size is the porcupine. Giving birth of a mother porcupine has been just like a human mother delivering an 80 pound baby.

Only sea turtles really migrate. Hatchlings make their way to seaweed drifts to feed and grow, and adult females migrate back to their birthing beaches to lay eggs.

Other reptiles may 'migrate' for short distances from suitable feeding habitat over the summer, to winter hibernation areas in the winter. These mass movements can sometimes even require road closures.

Yes, voles are most certainly mammals... they give live birth, feed their babies on milk, and have hair; they also breath air through lungs, and are warm blooded, which all together qualifies them as mammals. Good question! Remember, the only dumb question is the one that never gets asked! :-)

They have mammary glands and suckle their young.

The Cenozoic Era has the greatest variety and quantity of mammalian life.

• Mammals have fur, and birds have feathers
• Most mammals give birth to living young and birds lay eggs

It depends on the mammal. Some have fur, others have skin, blubber or other things. It really depends on the type of mammal.
