Bottlenose Dolphin Fact

The Bottlenose Dolphin are very unique in the moans, groans, squeaks, whistles, and grunts that they can sound as if they're a heavy metal band. Bottlenose Dolphins make music of their own. Many of the sounds they make could be duplicated by holding a balloon tightly by the filler hole and then letting the air out at different rates of escape.

Dolphins have Sonar

Dolphins use their sonar to produce sound and bounce it off objects which the animals then interpret. This echolocation is used to search for food, escape predators, navigate, stay with their pod, acoustically communicate with each other, and define the forms that make up their environment. A Bottle Nose Dolphin emitting sound and 'listening' to returning sounds.Dolphins and whales can also fine tune their sonar, adjusting frequency and amplitude of their signals. They can also echolocate loudly, quietly or not at all, as they so choose. Dolphins do periodically go silent, especially while resting. Studies with trained dolphins have been vital in understanding the nature of acoustic behavior. For example, it was found that dolphins can detect driftnets with their sonar. Ironically, the problem is to get dolphins to turn on their sonar to find and avoid these deadly nets.

Dolphins retired by U.S. Navy

When dolphins are replaced by unmanned, torpedo-shaped 'knifefish' underwater robots in 2017, the marine mammals will join a long list of species recruited to help out scientists and the military over the years. The U.S. Navy has revealed it is retiring its group of mine-seeking dolphins, in what will be the end of an era for human-animal military relations.

Dolphin Size:

The familiar bottlenose dolphin is around 8 feet (2.5m) long and weighs between 440-660 lbs (200-300kg). Because the forty species of dolphins are so diverse, they range in size. The smallest of the dolphin species, Maui's Dolphin, is around 4 feet (1.2m) long and weighs around 90 lbs (40 kg). The largest dolphin species is the orca, or killer whale. Male orcas grow to about 25 feet in length and weigh about 19,000 pounds.

Dolphin Behavior:

Dolphins are well known for their agility and playful behavior, making them a favorite of wildlife watchers. Many species will leap out of the water to view their surroundings and follow ships, often synchronizing their movements with one another. Scientists believe that dolphins conserve energy by swimming alongside ships, this is known as bow-riding. Dolphins live in social groups hundreds. They use echolocation to find prey and often hunt together by surrounding a school of fish, trapping them and taking turns swimming through the school and catching fish. Dolphins will also follow seabirds, other whales and fishing boats to feed on the fish they scare up or discard.

Facts about Dolphin's Giving Birth: 9-17 months depending on the species. When it is time to give birth, the female will distance herself from the pod, often going near the surface of the water.Number of offspring: Usually one calf; twins are rare. As soon as the calf is born, the mother must quickly take it to the surface so it can take its first breath. The calf will nurse from 11 months to 2 years, and after it is done nursing it will still stay with its mother until it is between 3 and 8 years old.


Dolphin

Dolphins are highly intelligent marine mammals and are part of the family of toothed whales that includes Orcas and Pilot Whales. They are found worldwide, mostly in shallow seas of the continental shelves, and are carnivores, mostly eating fish and squid. Dolphin coloration varies, but they are generally gray in color with darker backs than the rest of their bodies.

Beside humans, few other animals use tools to get their everyday chores done. Even fewer of them are marine mammals, so researchers in Australia were surprised to catch bottlenose dolphins employing conical sponges to dig in the seafloor. Mostly female dolphins use the snout-protectors, and only if their mothers showed them how, reports the Wall Street Journal. Marine biologists think the behavior can be traced back to a single, recent innovator who realized that her nose fit nicely in the empty cone of a sea sponge. Since dolphin babies spend 8 years nursing with their mother, use of the sponge appears to be more due to nurture than nature. Still, it’s unclear why most males eschew the tools.

Recently, a study showed that dolphins call each other by name, so this new information gives further insight into the intelligence that dolphins possess and the importance of social behavior in their lives.
