Spinner dolphins are regularly seen in the waters off Kona. follow boats. Our snorkel and manta the waters of Hawaii. Have you ever watched a video of a group of dolphins swimming next to a boat? If so, you probably saw them leaping, diving, splashing and having a ball. As you watched this display you may have wondered: Why do dolphins follow boats? Do they do it just for fun or is there another reason? While dolphins are known for their intelligence they also have a strong sense of curiosity. This brings up the first reason why they follow boats. The motion of a boat, its sounds, and the disturbance of the water prompt dolphins to go check out the strange object in their habitat. They approach the boat and swim alongside it to study this fast-moving object and observe the people on board. Maybe the people are playing loud music that creates vibrations. These animals are curious and won’t be able to resist checking out the activity. While some other sea creatures would much rather hide or swim away from this commotion, dolphins do the opposite. They like to go investigate! Not surprisingly, dolphins try to swim as fast as they can. When a dolphin swims in the wake of a boat, its body is carried along on the waves making them move even faster than usual. They burn less energy while achieving a higher speed. In a way, when dolphins follow boats, they are getting a free ride! Food is another reason they follow boats. Sometimes people on boats are so entertained by these racin...

• icon-facebook • icon-twitter • icon-email The month of March is when we celebrate and raise awareness for dolphins – our extremely intelligent friends with big, bubbly personalities. These beautiful marine animals are known for being sweet, playful and sociable, which sadly also makes them highly vulnerable to hunting and fishing. Habitat destruction, ship strikes, climate change, oil and gas development, and toxic contamination are the other significant threats to dolphin populations today. The devastating truth is that dolphins are one of the many magnificent creatures at risk of extinction. So please, join us in celebrating Dolphin Awareness Month and learn how you can make a difference. The Society of Marine Mammalogy recognizes 41 distinct dolphin species, nine of which are considered endangered by either the IUCN, the Endangered Species Act, or both, and one that may already be extinct. There are five species of freshwater dolphins listed on the IUCN Red List, all of which are classified as endangered or critically endangered. Tragically, this is all due to human activities. The Chinese river dolphin, or baiji, holds the unenviable record of being the first dolphin species driven to extinction by human beings. The mighty Yangtze River in China was the baiji’s home for 20 million years, but it took less than 50 years for humans to wipe them out. Luckily, there is still hope for other dolphin species. Animal experts, conservationists, animal scientists, veterinarians...

Large whales can communicate over huge distances (across entire ocean basins) using very low frequencies. Dolphins and porpoises however, usually use higher frequencies, which limits the distance their sounds can travel. In general, dolphins make two kinds of sounds, “whistles” and “clicks” (listen to the false killer whales on this page). Clicks are used to sense their surroundings through echolocation, while they use whistles to communicate with other members of their species and very likely, with other species too. It is also thought that each dolphin has a unique whistle called a ‘signature whistle’, which is used to identify an individual. What is echolocation? In general, as well as having extremely good eyesight that allows them to see both above and below the water, toothed whales (including dolphins) use a sense called echolocation to navigate and hunt underwater. This means that they emit sound waves and then detect and interpret the echoes that bounce back off of other creatures and objects in the water around them, allowing them to build up a picture of their surroundings. Dolphins hunt using their highly-developed echolocation, which means they can find food no matter how murky the water might be. Not only that but they can even use it to identify any prey that might be hiding, such as under the sand! Sperm whales also use echolocation to find their way around the dark depths of the ocean and to help with hunting for squid. Though only very brief, the clicks t...

Are these creatures mammals or fish? Do they have any predators to worry about? And what do dolphins think about sharks? These are some of the most commonly asked questions about dolphins, but they’re just scratching the surface. In the following guide, we’ll answer all of the above and so much more as we cover some fascinating (and surprising) facts about dolphins. If you are interested to Table of Contents • • • • • • • • • • • • 1. Are Dolphins Mammals? Although dolphins live in the sea and have some fish-like qualities, they are mammals. They fall under the order “cetacean”, which also covers whales and dolphins, and are thought to share a common ancestor with the hippopotamus. So, what makes dolphins different from fish? Well, for one thing, they breathe using lungs and not gills. Dolphins breathe through their blowholes and must visit the surface to breathe the oxygen. They are also warm-blooded and, more importantly, they give birth to live young. You may be surprised to learn that dolphin calves have hair on their rostrum (the beak area), potentially indicating that they are related to land mammals. 2. What Do Dolphins Eat? Like all cetaceans, dolphins typically subsist on a diet of fis...

Radekk / Getty Images Renowned dolphin researcher Louis Herman referred to dolphins as humans'"cognitive cousins" on account of the many characteristics they share with humans and great apes, even though cetaceans and primates are only slightly related. Cognition is an umbrella term used to describe high level brain functions like thinking, knowing, remembering, judging, and problem-solving. These functions allow us to use language, imagination, perception, and to plan. Problem-Solving An experiment conducted in 2010 at the Dolphin Research Center in Grassy Key, Florida, found that a bottlenose dolphin named Tanner tapped into his problem-solving capabilities to imitate the actions of other dolphins and humans while blindfolded. With his eyes covered by latex suction cups, Tanner resorted to another sense — his hearing — to determine the proximity and position of other dolphins and his trainer (in a follow-up study). Even though the sound of a human in the water differs from the sound of another dolphin in the water, Tanner was still able to mimic his trainer's changing swimming styles without being able to see him. skynesher / Getty Images Many other dolphins have risen to fame with their various feats of sophistication. Consider Kelly, a resident of the Institute for Marine Mammal Studies in Mississippi, who earned a reputation in the early 2000s for gull baiting. Her cheeky tricks started after the staff began rewarding the dolphins with fish every time they cleaned up ...

If you’re reading this, we have a lot in common. Like you, we know there’s something very special about dolphins. Because you share our fascination with dolphins, we asked our marine biologists to round up some remarkable dolphin facts so you can fully appreciate why dolphins are such an amazing species. Once you read these, you'll have everything you need to know about dolphins, and just a bit more. Here are some of the little known dolphin facts you’ll learn: • Which species of dolphin swims sideways. • How dolphins communicate and locate prey. • Which species can weigh 11 tons and which ones only weigh 350 pounds. • Which species have hair and which ones are bright pink. Let's dive in! Dolphins may swim through the water as gracefully as any fish, but they are not fish. Dolphins are mammals. This puts them in the ranks of other famous marine mammals such as whales, seals, and manatees. So why ? They: • are warm-blooded • breathe through lungs, not gills • give birth to live young • produce milk for their young • have body hair (doesn’t look like it, but they do!) Warm Blooded Warm-blooded means that their body is able to regulate its own temperature, so they stay warm even when the water temperatures around them are cold. Some of their native environments, such as the waters of the northern Pacific Ocean, can get very chilly. In these places, being warm-blooded is a big advantage for survival. Being warm-blooded also makes dolphins and other cetaceans less prone to infe...

• Scientific Name: Odontoceti • Common Name: Dolphin (Note: This name refers to the group of 44 species classified as Odontoceti; each has its own scientific and common name.) • Basic Animal Group: Mammal • Size: 5 feet long to over 30 feet long, depending on the species • Weight: Up to 6 tons • Lifespan: Up to 60 years depending on the species • Diet: Carnivore • Habitat: All oceans and some rivers • Population: Varies per species • Conservation Status: Bottlenose dolphins are considered to be of Least Concern, while about 10 species of dolphins are listed as Severely Threatened. Description Dolphins are small-toothed The forelimbs of a dolphin are anatomically equivalent to the forelimbs of other mammals (for example, they are analogous to arms in humans). But the bones within the forelimbs of dolphins have been shortened and made more rigid by supporting connective tissue. Pectoral flippers enable dolphins to steer and modulate their speed. The dorsal fin of a dolphin (located on the back of the dolphin) acts as a keel when the animal swims, giving the animal directional control and stability within the water. But not all dolphins have a dorsal fin. For example, the Northern Rightwhale Dolphins and the Southern Rightwhale Dolphins lack dorsal fins. Dolphins do not have prominent external ear openings. Their ear openings are small slits (located behind their eyes) which do not connect to the middle ear. Instead, scientists suggest that sound is conducted to the inner and...
