Fun Bottlenose dolphin facts
A bottlenose dolphin calf is born tail-first to prevent drowning. After the mother breaks the umbilical cord by swiftly swimming away, she immediately returns to her baby and take it to the surface to breathe.




Fun Bottlenose dolphin facts

Bottlenose dolphin sleep with one eye open and the other closed. Unlike humans, Bottlenose need to be awake to breathe. To prevent drowning while sleeping only half of the dolphin’s brain goes to sleep while the other half remains awake so they can continue to breathe. When the left brain sleeps, the right eye is closed and when the right half sleeps the left eye is closed.

Bottlenose dolphins play with members of their own pods as well as members of other pods. They will also play with masses of seaweed and even with turtles! Bottlenose dolphins also known to play with humans




Fun Bottlenose dolphin facts

The military of the United States and Russia train bottlenose dolphins as military dolphins for marine tasks, such as locating sea mines and detecting enemy divers. K-Dog, a bottlenose dolphin trained by the US Navy to find mines and boobytraps underwater goes to the ocean floor with a camera on it's flipper

Fun Bottlenose dolphin facts

Bottlenose dolphins can hold their breath for about 10 minutes. Bottlenose dolphins can dive to depths of 540 meters (1770 feet) and remain underwater for 8-10 minutes. Most Bottlenose dolphins do not, however, spend very much time at that depth. In fact, many dolphins spend the majority of their time in less than 2 meters (about 7 feet) of water.


Fun Bottlenose dolphin facts

Bottlenose dolphins are warm-blooded and their internal temperature is around 37 degrees Celcius (almost the same as that of humans). To conserve this temperature they are surrounded by a thick layer of fat called "blubber" just below the skin



Fun Bottlenose dolphin facts

Bottlenose dolphins see quite well both below and above the water.
Fun Bottlenose dolphin facts

Bottlenose dolphins normally travel at speeds of between 6 and 8 km/hr, as their motion is most efficient at these speeds. At higher speeds, dolphins tend to jump clear out of the water. This actually helps the Bottlenose dolphin save energy, as the air provides a lot less resistance than the water. It is estimated that dolphins can reach speed of up to 30 km/hr, but that is only in short bursts


Fun Bottlenose dolphin facts

Bottlenose dolphins that live in salt water cannot survive in fresh water environments. Because of the differing bouyancies, marine dolphins find it harder to move in fresh water; they often become exhausted and eventually begin to lose their skin


Fun Bottlenose dolphin facts

While the brains of most mammals have a relatively smooth surface, the brains of humans are extremely convoluted with many folds. The dolphin brain is even more “folded” than humans and was this way millions of years before the first appearance of humans


Fun Bottlenose dolphin facts

The dolphin's two mammary glands open into a pair of sacs on either side of the anal opening, and the calf's beak fits into the openings on the sacs. The nipple is grasped between the upper jaw and the tongue, and muscular contractions by the mother literally squirt milk into the calf's mouth. Nursing may continue for as long as 12 to 18 months after birth


Fun Bottlenose dolphin facts

The blowhole is an evolved nose that has moved upward to the top of the dolphin’s head. The nostrils of dolphins evolved into their echolocation system (the sensing system in which they make and recieve high-pitched sounds in order to orient themselves, catch prey, and communicate)


Fun Bottlenose dolphin facts

Bottlenose dolphins don’t have a sense of smell, but they do have a sense of taste and can distinguish between sweet, sour, bitter, and salty tastes.

Bottlenose dolphins, like humans, have sex even when they are not in heat which is unusual in the animal kingdom. Bottlenose dolphins are one of the three species that engage in sex for pleasure. Bottlenose dolphins are one of the very few animal species that will have sex face-to-face


Fun Bottlenose dolphin facts

Like many of their mammal relatives, dolphins shed skin sheds constantly. This also gets rid of any algae and bacteria that tend to stick to them.
Fun Bottlenose dolphin facts

The eyes of a dolphin produce “dolphin tears,” a slippery secretion which protects the eye against foreign objects and infection and reduces friction between the surface of the eye and surrounding sea water.
Fun Bottlenose dolphin facts

A bottlenose dolphin’s stomach consists of three compartments or chambers. The first chamber, acting as a "storage unit", is responsible for holding swallowed food until the other two chambers are ready to proceed with digestion. In this way a dolphin is able to rapidly consume large amounts of food. The second stomach of the dolphin functions much like that of the human where enzymes and hydrochloric acid are released to accomplish much of the digestive process. The third stomach retains the now digested food until it is passed to the small intestine for absorption into the circulatory system as nutrients for cellular metabolism.
Fun Bottlenose dolphin facts

A bottlenose dolphin can produce whistles for communication and clicks for sonar at the same time, which would be like a human speaking in two voices, with two different pitches, holding two different conversations. The clicks are used as a form of sonar, in which echoes of sounds from surrounding objects enable the animals to detect obstacles, other dolphins, and food. Dolphin used the whistles to communicate a particular emotional state and thus influence the behavior of other dolphins. Typically, the squeals denote alarm or sexual excitement.

DOLPHIN, a name properly belonging to the common cetacean mammal known as Delphinus delphis, but also applied to a number of more or less nearly allied species. The dolphins, bottle-noses, or, as they are more commonly called, “porpoises,” are found in abundance in all seas, while some species are inhabitants of large rivers, as the Amazon. They are among the smaller members of the cetacean order, none exceeding 10 ft. in length. Their food is chiefly fish, for the capture of which their long narrow beaks, armed with numerous sharp-pointed teeth, are well adapted, but some also devour crustaceans and molluscs. They are mostly gregarious, and the agility and grace of their movements in the water are themes of admiration to the spectators when a “school of porpoises” is playing round the bows of a vessel at sea. The type of the group is the common dolphin (D. delphis) of the Mediterranean and Atlantic, which usually measures 6 to 8 ft. in length, and is thickest near the centre, where the back fin rises to a height of 9 or 10 in., and whence the body tapers towards both extremities. The forehead descends abruptly to the base of the slightly flattened beak, which is about 6 in. long, and is separated from the forehead by a transverse depression. The mouth is armed with sharp, slightly curved teeth, of uniform size, varying in number from forty to fifty on each side of both jaws. The aperture of the ear is exceedingly minute; the eyes are of moderate size and the blow-hole is crescent-shaped. The colour of the upper surface is black, becoming lighter on the flanks, and perfectly white below. Dolphins are gregarious, and large herds often follow ships. They exhibit remarkable agility, individuals having been known to leap to such a height out of the water as to fall upon the deck. Their gambols and apparent relish for human society have attracted the attention of mariners in all ages, and have probably given rise to the many fabulous stories told of dolphins. Their appearance at sea was regarded as a good omen, for although it presaged a tempest, yet it enabled the sailors to steer for a place of safety. The dolphin is exceedingly voracious, feeding on fish, cuttlefishes and crustaceans. On the south coast of England it lives chiefly on pilchard and mackerel, and when in pursuit of these is often taken in the nets. The female brings forth a single young one, which she nurses most carefully. Her milk is abundant and rich, and during the operation of suckling, the mother floats in a slightly sidelong position, so as to allow of the necessary respiration in herself and her young. The dolphin was formerly supposed to be a fish, and allowed to be eaten by Roman Catholics when the use of flesh was prohibited, and it seems to have been esteemed as a delicacy by the French. Among the seafaring population of Britain the name “dolphin” is most usually given to the beautifully coloured fish Coryphaena hippuris—the dorado of the Portuguese, and it is to the latter the poet is alluding when he speaks of “the dying dolphin’s changing hues.” Many other allied genera, such as Prodelphinus, Steno, Lagenorhynchus, &c., are also included in the family Delphinidae, some of which live wholly in rivers. Beside these there is another group of largely freshwater species, constituting the family Platanistidae, and typified by the susu (Platanista gangetica), extensively distributed throughout nearly the whole of the river-systems of the Ganges, Brahmaputra and Indus, ascending as high as there is water enough to swim in, but never passing out to sea. It is about 8 ft. long, blind and feeds on small fish and crustaceans for which it gropes with its long snout in the muddy waters at the bottom. Inia geoffroyensis, the single species of its genus, frequents the Amazon, and reaches an extreme length of 8 ft. It is wholly pink or flesh-coloured, or entirely black, or black above and pink beneath. A third is the La Plata dolphin, Stenodelphis blainvillei, a species about 5 ft. in length. Its colour is palish brown, which harmonizes with the brown-coloured water of the estuary of the Rio de la Plata
