Dolphins and Porpoises
Considered not a fish, dolphins and porpoises belong to the group of toothed whales that have skin, not scales. The significant difference between them is that dolphins have a beak, a melon-shaped head and a dorsal, while porpoises have none.

What is a dolphin's skin like?
Dolphins have smooth skin that feels like rubber. Because their skin is slippery, water flows easily around it. To keep their skin smooth, dolphins shed it constantly. Dolphins have a special layer of fat under their skin called blubber. Blubber acts like a winter coat and keeps dolphins warm in cold water. Dolphins that live in the cold water often have a thicker layer of blubber than those that live in warmer waters. Blubber is also light and helps keep dolphins from sinking while they swim a little bit like an inner tube.
How many muscles do you use when you walk?
Walking typically involves the use of over 200 muscles in the body, which work together to move your legs, stabilize your body, and maintain balance. These muscles in the legs, hips, core, and back all play a role in the complex coordination required for walking.
Why are the Spotted Dolphins endangered?
Not all spotted dolphins are, as the once sparse population of Atlantic spotted dolphin in the Bahamas of only 80 has boomed to 200, making the total population around 100,000.
However, the Pantropical spotted dolphin population (in eastern pacific ocean) has dwindled to endangered levels as many have died due to being caught in special tuna nets.
Recently and thankfully, they have revamped the net making to correct this fatal error.
Can you talk and breathe at the same time?
YES. but you know that you cannot keep your eyes open while you sneeze - fact. You normally are breathing out when you are talking. It's the outbound air flow that vibrates your vocal cords and produces the fundamental sounds that become speech. You can do this breathing in but it's hard.

Why does water always stay straight or level?
It doesn't... always! First of all, water will only remain flat when it is completely undisturbed. In a lake or the ocean, the wind creates waves on the surface. In a river, the water is flowing downhill, and the surface of the water is certainly not flat.
However, generally we think of water as being flat. That's not really true either. The oceans are certainly not flat -- they are curved! The oceans are on the surface of the Earth, which is a very big sphere. So while the ocean looks flat to us, it is simply because we don't have enough perspective to see that they are curved... but they are! Think about a globe and you can easily see that the oceans are very curved.
However, all this aside, if you have a glass of water, and let it sit undisturbed, the water level is flat. This is because the pull of gravity is equal across the face of the water. The water molecules are free to move throughout the liquid, and the gravity affects each water molecule equally, pulling them all down the same. That is why the water level stays flat in a glass.
The reason the oceans are curved is in fact the same reason. The pull of gravity can be approximated as coming from the center of the Earth. So if you are on one side of the Earth, the pull of gravity is in exactly the opposite direction as if you were on the other side (some people like to think of Australians as being upside down, which is of course ridiculous, but that's that same idea). Because gravity is pulling the water molecules equally towards the center of the Earth, the surface of the water is the surface of a sphere, which is of course, curved.
How many atolls exist in the world?
Bryan (1953) lists about 400 atolls. The full article is available through http://www.botany.hawaii.edu/faculty/duffy/arb/019-23/v019-23.pdf. This is not a definitive list as the definition of an atoll is still the subject of discussion discussion.

How does a crab breathe under water?
Crabs have gills that extract oxygen from the water, allowing them to breathe underwater. They take in water through their mouths and absorb the oxygen through their gills, while releasing carbon dioxide back into the water.
How much money do dolphin trainers earn?
Dolphin trainers can earn anywhere from $25,000 to $75,000 per year, depending on factors such as experience, location, and the specific facility they work for. With more experience and certifications, trainers may have the potential to earn higher salaries.
What are the odds of of being killed by a dolphin?
the odds our 0%
Actually, it's not zero. It's extremely low, but it's not zero. Over the last few years, a few people have been killed by dolphins. Dolphins don't normally attack humans...I think all the deaths were accidents.
On average, it is estimated that hundreds of dolphins die each day due to various reasons such as pollution, bycatch in fishing nets, and habitat destruction. The exact number varies depending on different factors such as location and threats in that particular area.
How has the dolphin population changed over the years?
The dolphin population has increased over the years due to the new advances in the animal artificial insemination field. While the above is true sonar is becoming a problem with dolphins and whales. It disorientates them and they are connecting this with beached whales in particular. I saw a very disturbing video on Japan and how they hunt Dolphins. They have a vast net set out by 3 fishing boats and then they use long slender rods which they hit so it disorientates the Dolphins and they become frantic in these nets. No matter how disoriented or frantic they are if one Dolphin is in distress then the others will come to comfort them and stay in a group which is like shooting fish in a barrel for the Japanese. There is no emotion when these so-called fishermen haul them still alive into the boats and then take them back to their fisheries. It shows them dragging and gutting Dolphins still alive and I couldn't bring myself to watch the whole video and neither could my husband. Dolphins do a lot of good for the Navy (used as tracking devices) to helping children in programs that have MS, AHD/ADD and many other diseases. The Dolphin is highly intelligent and can communicate with humans, and, in fact, are much like humans, but I would say much more loyal to their own species. Of course my husband and our friends all signed the petition against this cruelty and there is no need whatsoever to kill Dolphins. At the rate Japan is catching these Dolphins it could lower the population. Humans are the ones the misdirect the balance of nature.
Why dolphins and whales do not have gills?
Dolphins and whales are mammals, not fish, so they do not have gills. They breathe air through blowholes on the top of their heads, just like humans breathe through their noses. This allows them to dive deep into the ocean and still come up to the surface to breathe.
