Many dolphins are grey in color, some species have various patterns of black and white, and a few are even pink. In terms of behavior, all species of dolphins are quite gregarious.
Botos have the characteristic dolphin smile and, unlike their marine cousins, bulbous foreheads and long, skinny beaks. Most strikingly, males can be pink. The coloring is believed to be scar tissue from rough games or fighting over conquests.
Understanding AlbinismAlbinism is a genetic condition where people are born without the usual pigment (color) in their bodies. Their bodies aren't able to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair color. So most people with albinism have very pale skin, hair, and eyes.
Albino WhalesAlthough rare, albinism has been reported in 20 different whale and dolphin species, including humpback whales, bottlenose dolphins, sperm whales, and pilot whales. In some cases, pigment may be reduced but not fully blocked.
In fish. As with other animals, it has been stated that for fish to be properly described as "albino", they must have a white body and pink or red eyes.
A total of 261 bottlenose dolphins were found stranded between Louisiana and the Florida Panhandle, officials said. Bottlenose dolphins are usually found in waters with high saline levels, according to the NOAA. “Some of the dolphins have had freshwater skin lesions that are common with freshwater exposure,” she said.
Pinky is an albino bottlenose dolphin found in Calcasieu Lake, Louisiana. Pinky was first spotted in June 2007 by a boat captain, Erik Rue. The dolphin has become a tourist attraction, and conservationists have asked visitors to leave the dolphin alone.
Porpoise species are actually very rare in Louisiana waters, while bottlenose dolphins are extremely common in the baitfish rich estuaries along the gulf coast.
These complex hunters are capable of inflicting serious injuries upon each other and humans. Dolphins at swim-with attractions have been known to seriously hurt humans by butting them. The resulting injuries have included lacerations and broken bones.
Overview. As a result of whaling and other human and natural influences, sixteen species of whales and dolphins are considered to be in danger of extinction according to the Endangered Species Act.
Reputation: Botos, or Amazon river dolphins are pink, quiet, solitary, blind mythical mammals.
They are often friendly and curious toward people. Amazon, or pink, river dolphin (Inia geoffrensis). Also called boto, bufeo, and pink dolphin, it is common in the turbid waters of the Amazon and Orinoco river basins.
Are pink dolphins going extinct?
There are at least 44 species of
dolphins divided into oceanic and river families and they are found in waters all over the world.

Like most other dolphins, pink dolphins sleep with one eye open. They can do that by putting one half of their brain to sleep and keep the other side of the brain conscious and functioning. They alternate those sides to be able to rest and at the same time be on the lookout for predators.
While the botos have a reputation for leading fishers to areas rich with fish, they are also known for luring them to dangerous areas and deliberately confusing navigators and sinking their boats.
According to the WWF, there are only an estimated 2,000 pink dolphins left in the Pearl River Delta—the minimum number that conservationists believe are needed to sustain the species'.
During mating season male dolphins can become very aggressive towards one another and cause serious injuries when competing for females. It is believed that the pink amazon river dolphin is considered the most attractive dolphin of them all and is attacked far more often as a result by competing male dolphins.
Dolphins can become deaf for a variety of reasons. The most common cause is age-related hearing loss, said Dorian Houser, a marine biologist at the National Marine Mammal Foundation in San Diego.
The “pink” appearance on some whales recently could be the result of colouration on their undersides. They welcome more pics and video of such mammals.
The Ganges river dolphin can only live in freshwater and is essentially blind. They hunt by emitting ultrasonic sounds, which bounces off of fish and other prey, enabling them to “see” an image in their mind.
The Chilean dolphin (Cephalorhynchus eutropia), also known as the black dolphin, is one of four dolphins in the genus Cephalorhynchus. The dolphin is only found off the coast of Chile; it is commonly referred to in the country as tonina.
The science makes one fact undeniably clear: wild dolphins of some species are noted for seeking out social encounters with humans. The phenomenon of lone sociable dolphins – for whom human contact appears to substitute for the company of their own kind – is documented extensively in the scientific literature.
Find a comfy spot and keep watching for tell tale signs The following signs often mean that there are whales or dolphins in the area: feeding birds circling above a particular spot, areas of still water or oily slicks (footprint), breaking wave crests or waves moving in the 'wrong' direction, big splashes and bursts of
Shark species are nondescript in colour, varying from gray to cream, brown, yellow, slate, or blue and often patterned with spots, bands, marblings, or protuberances.
Based on current metrics for intelligence, dolphins are one of the most intelligent animals in the world. While intelligence is difficult to quantify in any organism, many studies suggest that dolphins are second only to us humans in smarts. However, dolphins also excel intelligence-based tests.
Dolphins can't breathe under water because they don't have gills. They have lungs just like people and must breathe air. Dolphins have to live in water because they would overheat and dry out on land. Their bodies and body functions have evolved for life in the water.
There are many anecdotal accounts of dolphins saving humans from death and disaster, either by guiding them to shore, fending off sharks or helping them to remain afloat until help arrives.
Answer: Large species of sharks, eat small species of dolphins or calves. Also, occasionally killer whales eat small dolphins too. The larger dolphins are apex predators which mean that they are at the top of the chain food.
