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.

How does technology use echolocation?
it is where the bat sends out a sound that bounces of it's prey (moths, midges or mosquitoes) and back to the bat so it knows exactly where it's prey is.
Did you know a pipistrelle bat can eat 3000 flying insects in one night!
Yes
Yes, they do.
Yes, being mammals, dolphins breathe with lungs rather than gills. Rather than breathing through the nose and mouth, they breathe from a blowhole which closes before the dolphin goes into the water, so water will not enter the blowhole.
Where would you more likely find Dolphins?
dolphins can live in both rivers and seas, they are quite common in unpolluted areas but the most likely places to find them are in marine parks and zoos, or in dolphin experiences such as swimming with dolphins :)
From Wikipedia:
The habitat of the vaquita is thought to be restricted to the northern area of the Gulf of California. The vaquita lives in shallow, murky lagoons along the shoreline and is rarely seen in water much deeper than 30 meters; indeed, it can survive in lagoons so shallow that its back protrudes above the surface. The vaquita is most often sighted in water 11 to 50 metres deep, 11 to 25 kilometres from the coast, over silt and clay bottoms. Its habitat is characterised by turbid water with a high nutrient content. Other characteristics of its habitat are strong tidal mixing, convection processes and high primary and secondary productivity.
How many babies can Hector's dolphins have at one time?

well technically because there are some mountains near the amazon river and there are pink dolphins in the amazon river
Do horses sleep with one eye open?
Giraffes don't sleep with one eye open. There's no point in keeping an eye open unless there's a brain awake to interpret what the eye is seeing. And the only animals considered to be able to sleep with half the brain at a time are whales and Dolphins.
Wonderful, eating dolphin have a similar taste to Horse. Go ask a Frenchman.
Whales started out as land living mammals - some still have remains of hind legs in their bodies - which eventually somehow turned into sea-living mammals.
And while many parts of their bodies changed to fit a swimming lifestyle, they still breathe air, with lungs.
If whales and dolphins did not come up to the surface to breathe, they would drown and there would not be any dolphins or whales!!
How are dolphin helpful to humans?
They're helpful because they are the most sociable/playfulness creatures in the bays ever. They sense when people are in trouble easily and most of the time they will save a human from danger due to their huge mind of intelligence.
Dolphins can learn if they see a person friendly and playing with him for a month then anything the person does in front of the dolphin then the dolphin does the same thing if you let him to see you every day then it would've happen.
There is no official method for differentiating the 2 animals.
Dolphins are not normally classified as whales, however they can be classified as part of the whale family because in many ways they are alike.
Why is dolphin classified as a mammal?
Dolphin is classified as mammal as it possess all mammalian characters i.e. hair , mammary glands for feeding young ones , 7 cervical vertebrae and so on .
dolphins r mammals bcoz they need air to breathe and are warm and have proper flesh on the inside
What temperature is it in a dolphins habitat?
The temperature of a Dolphin's habitat is -86 Degrees Fahrenheit or less.
Baiji eat small fish such as: shrimp, catfish, and other small creatures.
Do dolphins live in pack or do they live alone?
Answer 1: I believe they go in groups of 3-6 .
Answer 2: Dolphins sometimes, but rarely, live alone. They mostly live in groups of from ten to 30 animals; and such groups are called "pods," just as with whales.
Dolphins, then, travel and live in pods, not packs. Wolves live and travel in packs. Dolphins live and travel in pods.
A pod can, though rarely, be very small... only a pair, sometimes. And in some -- also rare -- cases, a single pod can consist of thousands (certainly hundreds) of animals. And, yes, they sometimes travel and live alone.
If a dolphin is traveling/living alone, and not in a pod, it's usually for a reason. S/he may be ill; or s/he may have done something which no other animal in the pod could tolerate. There may have been some kind of fight for dominance, and s/he lost; then the group rejected him/her (though that rarely happens). S/he may also have been in captivity once, and then released to the wild (usually after some training in how to fend for himself/herself).
That last possibility is the most sad; and, in fact, most once-in-captivity animals are best moved to research facilities such as a very famous one in the Florida Keys where they may be studied (but without harming them), and they may live in real sea water in a contained area that's actually in the ocean; and where they are routinely interacted with by humans, but not forced to perform or anything like that.
Dolphins are extraordinarily intelligent animals; some researchers believe that if they had human language, we'd realize that they're likely as smart as humans. They're extremely social, and caring of other pod members. Even wild dolphins seem to just intuitively understand when the humans with whom they come into contact have ultimately good intentions (though they, like humans, sometimes get fooled... which is the human's fault, not the dolphin's); and they have even been known to protect humans who are floating out in the ocean (after their boat capsized or something, and who need rescuing), from sharks... ramming the sharks with their heads, hoping to rupture one of the Shark's internal organs and disable or even kill it. Wild dolphins are frequently seen traveling alongside large boats as the move through the water, swimming in the bow's wake at incredible speeds, obviously enjoying themselves, no end; and humans skin- and SCUBA-divers are often able to swim with them even in the wild, with no fear. They're very peaceful and gentle... quite remarkable animals.
No they do not sleep in schools but they sleep with one eye open partly because of enemies but because they have to think to breath. And if they do not think of breathing they will die, if they are knocked unconsious then they will die because they are not thinking of breathing.
Dolphins have a thick layer of fat that insulates their bodies when the water they live in becomes too cold. They also conserve body heat when necessary.
What does a dorsal fin on a fish do?
helps it swim along and gives it bost to swim away from enemies!
love you djuan from m
Whats the difference between sharks and dolphins?
Sharks
Eggs
No spinal bones
Fish
Eat people (0riginal answer)- This is moronic to say. Sharks are highly afraid of people and will do what they can to avoid them. The majority of shark attacks are due to the animal being provoked or a case of mistaken identity such as a surfer which looks very much like a sea turtle when looking up from beneath. The sea turtle is a natural food source of most sharks. There more fatalities a year due to lightening striking a person than shark attacks. Ar person is more likely to die from a toaster than a shark or a vending machine fall on them.
Dolphins
Live Birth
Spianl bones
Animal (original answer)- Sharks are also considered animals; therefore this is not a true difference. The classiification for Sharks is as follows: Kingdom:Animalia, Phylum: Chordata, Class: Chondrichthyes (cartilaginous). The classification for the Dolphin is as follows: Kingdom: Animalia, Phylum:Chordata, Class: Mammalia. As you can see, the difference splits at their Class.
Suck
Sharks are cold-blooded, and filter the water around them to get the oxygen out of the water, but dolphins are warm-blooded, therefore mammals, who surface to take a breath of air. Not through their mouth or nose like humans, but through their blowholes, a hole in front of their dorsal fin that closes tightly shut when the dolphin dives back down into the water.
dolphins are mammels and need air to survive. However, sharks are fish and have gills. unlike the dolphin who has lungs.
Sharks are cold-blooded, and are a species of fish; Dolphins are warm-blooded, and are mammals.
A shark has big sharp teeth and dolphin has got little and not sharp teeth
a sharks top fin is straght up with ridges and a dolphins top fin is curved
Yes, they can smell.(1) It is believed that Dolphins smell by taste. Although they might
have weaker than human ability. Dolphins can even taste/smell the blood of other
Dolphins during slaughter,(2) in the Dolphin slaughter pens of Japan.
