There are many types of dolphins , around 40 different species. While the majority of them spend their lives in saltwater, many can survive just fine in freshwater. The smallest of their kind is feet long , while the largest is 30 feet! They are not only the friendliest or caring creatures but also the most intelligent ones. It is believed by scientists that comparing the ratio size of brain to body, dolphins take the 2nd place right after the humans!
Dolphins never chew their food, they swallow it as a whole. Their teeth are used only to catch their prey. It has been proved by scientists that dolphins give themselves names.
When they are asleep, one part of their brain remains alert and awake. This keeps them safe from potential predators, and enables them to breathe while sleeping. They love to play with members of their pods and are friendly to even humans. They are often seen playing and teasing other animals living underwater. Opposite to their name, Killer Whales belong to the dolphin family. Killer Whales, reaching up to a length of 30 feet, are the biggest of their kind.
Not known to many, Dolphins can migrate if their needs of food are not met. Even though they are not migratory animals, they will move to places where they have enough food and the climatic conditions are suitable to their body temperatures. Dolphins have very delicate skin, getting injured at the slightest touch of hard surface.
However, due to their fast healing attribute, even the deepest of wounds can be healed within a short time.
From an outside perspective, dolphins may seem to communicate much like humans. However, researchers are still investigating both how dolphins communicate and what information they are able to pass to each other. Despite lacking hands, dolphins are adept at using tools. For instance, one of their more specialized tricks is to carry a sponge at the end of their beak, also know as a rostrum. This acts like padding, protecting them from sharp rocks as they dig through the seafloor for food.
Zoological facilities, aquariums, and other places, such as Dolphins Plus , give people a way to learn more about these remarkable animals. The educated professionals who work there can share general information, threats and conservation efforts, and the latest research findings on how these animals cognitively function, communicate, and adapt. These places are both fun for the viewing public and offer a great learning experience. One of the fascinating things about these marine mammals is their complex methods of communication.
So how do dolphins communicate? There are three main ways: whistles, echolocation, and social communication. Dolphins communicate through more than just clicks and whistles. They can also slap the water's surface with their tail or bodies, which is officially termed breaching.
Dolphins can make squeaks, buzzes, whistles, clicks, and a wide array of other crazy noises. These whistles can be heard by others of the species from miles away. Click on the links below to listen to the whistles of Atlantic bottlenose dolphins at Dolphins Plus. Echolocation serves for both communication and for navigation.
Echolocation is seeing with sound, much like sonar on a submarine. The dolphin emits a sound and then listens for the echo as that sound bounces off of objects, these sound waves travel back to the dolphin.
Dolphins are able to get much more information out of the sound than humans. This includes the size and shape of objects or obstructions near them and even what material they are made of. There are dozens of species of dolphins and each has their own unique habitats, appearance, and behaviors. 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. In fact, many dolphin species can form groups of over 1, individuals, known as super pods! Dolphins come in all shapes and sizes, and each species has their own unique features.
You may not expect to find a dolphin in freshwater areas, but this species thrives in the Amazon River. It's also called the boto or bufeo dolphin and its skin turns pink as it matures. Here's another entry to the list of freshwater dolphins. As you'd guess from the name, this species can be found in the Ganges River in India.
It has a unique habit of swimming sideways, allowing it to sidle up to food. This striking, highly social dolphin species is found off the coast of Argentina and in parts of the Indian Ocean. It's best known for a panda-like black and white color pattern. Risso's dolphins love deeper waters, where they seek out a diet of squid and other deepwater fish species. However, their favorite prey fights back and older members of this species may have a mottled pattern of battle scars from squid attacks.
Did you know that killer whales are members of the dolphin family? These animals, also commonly called orcas, are the world's largest dolphins. How big are they? Larger individuals can grow over 30 feet long and weigh 11 tons. They typically have a bold black and white pattern similar to Commerson's dolphin. They use some of the most sophisticated and unusual communications of all dolphin species.
These playful dolphins have earned their name, in part, for the high jumping spins they take out of the water. These aerial acrobatic tricks make them a favorite among dolphin-watchers. They are found throughout the world, preferring warm and shallow waters.
Once you've seen one of these members of the dolphin family, you'll never forget them. The short-finned pilot whale has an unusual, squared-off head and lacks the long beak of most dolphin species. Pilot whales are very social and travel in pods of up to 50 members. This shy, elusive dolphin species share a similar black and white color pattern to killer whales, but they are a fraction of the size. They are rarely seen by humans as hourglass dolphins are one of the few dolphin species who favors the Antarctic area.
Although the bottlenose is the most famous dolphin species, there is a good chance you've seen a striped dolphin in action at an aquatic center. These attractively striped animals can live in very large groups, and they perform elaborate acrobatics when they leap into the air. We saved the bottlenose dolphin for last for two reasons.
Flipper, the world's most famous dolphin, was a bottlenose dolphin. The other reason is they hold a special place in our hearts, since most the dolphins at Dolphins Plus are Atlantic bottlenose dolphins.
These majestic animals are dark grey and, as you'd expect from the name, have a short and blunt rostrum. Bottlenose dolphins live throughout the world in warmer waters. They have a number of interesting features ranging from how they look to how they interact with each other. Bottlenose dolphins are varying shades of grey with a lighter belly counter-shading , which helps conceal them from predators. They have a streamlined body that allows them to swim up to 20 mph.
The typical length for an adult bottlenose dolphin can range between 6 to over 12 feet and they can weigh over a 1, pounds.
The bottlenose dolphin's diet varies depending on the region where they live. These skillful predators primarily eat fish, but can also hunt other marine life such as squid. Dolphins have some sophisticated ways to catch a meal. Some of their tactics include herding prey into muddy areas and even catching leaping fish out of the air. They tend to hunt in a group, which makes the foraging process very effective.
Dolphins thrive in both tropical and cooler, more temperate waters. Humans have encountered dolphin pods both near shore and in deep offshore waters like the Indian Ocean. Some dolphin groups stay in one area for a lifetime while others migrate. When their calves are born they typically weigh around pounds, compared to full-grown dolphins that can weigh over a 1, pounds.
That's quite a difference! Bottlenose dolphins start out quite dark in color, lightening as they mature. Dolphins are under threat worldwide, mainly human generated threats. Two of the biggest issues are entanglement in fishing gear and nets, and pollution.
Dolphins often pursue the same fish species that commercial fishing ships are hunting and may get accidentally caught in their nets. While on an expedition to the whales in the North Atlantic, researchers ran across one group that had apparently adopted a deformed dolphin into their pod.
The development of the blowhole was an essential part of dolphin evolution, allowing the sea-faring mammals to quickly inhale and exhale air at ocean's surface while keeping an eye out for predators and prey in the water below. Oh, and apparently it's really handy for blowing rings too. Along a stretch of coastline in Laguna, Brazil, local fishermen and dolphins have formed a partnership in the pursuit of a meal. Researchers, who published a study on this unique behavior, describe how the unlikely allies work as a team to wrangle fish : "Through highly synchronized behavior with humans, cooperative dolphins in Laguna drive mullet schools towards a line of fishermen and 'signal,' via stereotyped head slaps or tail slaps, when and where fishermen should throw their nets.
While studying dolphins off the coast of South Korea, biologists were treated to a particularly moving scene of dolphin solidarity.
One group of dolphins were observed coming to the aid of their sick or injured counterpart who was struggling to stay afloat. The dolphins formed a 'raft' of sorts with their bodies, propping up their pod-mate to keep her from drowning.
While we might have a lot to learn about the intricacies of dolphin emotions, it seems pretty clear when they're having a good time as they leap through the air with utmost precision , or engage in artful displays of underwater acrobatics.
Sure, humans and dolphins come from completely different worlds, but there's nothing quite as unifying as the shared joy of being alive. Actively scan device characteristics for identification.
