Dolphins and other toothed whales locate food and other objects in the ocean through echolocation. In echolocating, they produce short broad-spectrum burst-pulses that sound to us like "clicks." These "clicks" are reflected from objects of interest to the whale and provide information to the whale on food sources.

May 31, 2018 — Millions of years of evolutionary fine-tuning have made dolphins phenomenally good at using echolocation to orient themselves, find food and communicate with one another. But how ...

Echolocation allows dolphins to “see" by interpreting the echoes of sound waves that bounce off of objects near them in the water. To echolocate objects nearby, dolphins produce high-frequency clicks. This information is critical for dolphins to find food and navigate in dark or murky waters.

Echolocation is an amazing way for dolphins and other ocean animals to find their food. Echolocation works like an echo. Sound waves are sent out, and eventually hit an object then they bounce back giving the host information. They can tell how far away an object is, how big it is and if it is moving below them or above them.

And so, how does a hungry dolphin locate a nearby school of fish? The answer: Echolocation! Seeing with sound. Echolocation is the process of using reflected sound to obtain information about a nearby object. It could be food, another dolphin, or even an approaching iceberg perhaps.

Dolphins can locate objects outside of their visual range using echolocation. Dolphins hear the sounds of their clicks reflected to them. Whereas humans rely on light reflected to us, sound waves carry more information to the dolphin. Sound can give more of a three-dimensional picture than vision.

Dolphins use echolocation to create an impression of the world around them. These pictures hold a wealth of three-dimensional information like depth, making it difficult to translate into flat images.

The melon is a big part of the overall process for hearing and for echolocation that the dolphins use. They have antennae like reception through their teeth that allows them to get information regarding sounds. They use echolocation to assist them with finding objects, determining their size, and more.
Dolphin is the common name of aquatic mammals within the infraorder Cetacea.The term dolphin usually refers to the extant families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), named Iniidae (the New World river dolphins), and Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin).
The Amazon river dolphin, also known as the pink river dolphin or boto, lives only in freshwater. It is found throughout much of the Amazon and Orinoco river basins in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela. It is a relatively abundant freshwater cetacean with an estimated population in the tens of thousands.

Dolphins can live for a very long time and females tend to live longer than males. Female bottlenose dolphins have been known to live for more than 60 years and dolphins up to 48 years old have given birth. The oldest known dolphin is a bottlenose dolphin named Nicklo by researchers studying dolphins in Sarasota Bay in Florida.
Dolphins and porpoises differ in their faces, fins, and body shapes. Dolphins have longer noses, bigger mouths, more curved dorsal fins, and longer, leaner bodies than porpoises. The Northeastern Offshore Spotted Dolphin, shown here, has a falcate, or sickle-shaped dorsal fin and light spotting on the belly.
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.
Most dolphins are marine and live in the ocean or brackish waters along coastlines. There are a few species, however, like the South Asian river dolphin and the Amazon river dolphin , or boto, that live in freshwater streams and rivers.

Dolphin attacks can be fatal. Ultimately, dolphins are seriously scary because they can seriously kill you. Nat Geo Wild describes a 1994 case in which two men in São Paulo, Brazil, were rammed by a dolphin. Sadly, one man passed away due to internal injuries sustained during the incident.
The Amazon river dolphin , also known as the pink river dolphin or boto, lives only in freshwater. It is found throughout much of the Amazon and Orinoco river basins in Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, and Venezuela.
Feeding dolphins raw cod or raw salmon improves their "trust" and interactions with the player, depending on the amount of fish fed. When dolphins are fed raw cod or raw salmon, they swim to the nearest shipwreck, buried treasure, or ocean ruins.
Dolphins eat a variety of fish, squid, shrimps, jellyfish and octopuses. The types of fish and other creatures dolphins eat depend on the species of dolphin, where the dolphins live and the wildlife that shares their habitats.
When sleeping , dolphins often rest motionless at the surface of the water, breathing regularly or they may swim very slowly and steadily, close to the surface. In shallow water, dolphins sometimes sleep on the seabed rising regularly to the surface to breath.
Common bottlenose dolphins (referred to hereafter simply as bottlenose dolphins) are found throughout the world in both offshore and coastal waters, including harbors, bays, gulfs, and estuaries of temperate and tropical waters (estuaries are the areas where rivers meet the sea). They are one of the most well-studied marine mammals in the wild.

Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
Dolphins are active predators and eat a wide variety of fishes, squids, and crustaceans such as shrimps. The foods available to a dolphin vary with its geographic location. Dolphins show strong preferences for certain species of food fish. Coastal dolphins tend to eat fishes and bottom-dwelling invertebrates.

Dolphins use a plethora of defense mechanisms to defend themselves from danger. These include using their vast intelligence, incredible speed, communication, echolocation, and traveling in pods. In fact, dolphins are able to scare off and intimidate their main predator (sharks) just by swimming in large groups.
A group of dolphins is called a pod. Dolphins are social mammals that interact with one another, swim together, protect each other, and hunt for food as a team. Pod life plays a very important role in protecting dolphins from predators such as sharks. Most pods contain anywhere from 2 – 30 dolphins depending on the species and the situation, however there are occasions when pods gather…
