Porpoises are shy animals that travel in small groups, called shoals. They may live alone, with one other, or in small groups, depending on the availability of food. They avoid boats and, unlike dolphins, seem to fear humans. Scientists know much less about the behavior of porpoises in the wild than dolphins, due to the porpoises’ retiring.
Porpoises live in small social groups and are thought to have simpler social lives than dolphins. Compared to many dolphins, porpoises grow quickly, breed at an early age and do not live beyond 20 years. For example many female harbour porpoises start breeding before they are three years old, at the same age, bottlenose dolphins are still staying close to, and learning from, their mothers.
Dolphins, Porpoises, and Whales An Action Plan for the Conservation of Biological Diversity: 1988-1992. dolphins face extinction in this century unless present trends are reversed. Second, the river dolphins are largely tropical and therefore occur entirely within the boundaries of the developing nations, where human population growth is the greatest and environmental conservation is most.Watching whales, dolphins and porpoises in the wild is a privileged experience and everyone has their own unique encounters with these amazing creatures.

Porpoises are related to dolphins, but are generally smaller and stouter. These mammals have a small, rounded head, blunt jaws, and flattened, spade-shaped teeth. They hunt fish, squid, and shelled creatures called crustaceans. Porpoises use sound to find prey and communicate. They generally live in coastal waters, rather than out in the open sea. These animals are shy creatures and, unlike.

Dolphins, like whales, are mammals that live permanently in the water.Along with whales and porpoises, they belong to the cetacean group. There are 41 species of dolphin, ranging in size from less than 1.4 metres (less than 5 feet) long to the killer whale, or orca, about 9 metres (30 feet) in length.Dolphins have a single backward-curving, dorsal (back) fin, and many species have a beak-like.
Cetaceans (whales, dolphins, and porpoises) are an order of mammals that originated about 50 million years ago in the Eocene epoch. Even though all modern cetaceans are obligate aquatic mammals, early cetaceans were amphibious, and their ancestors were terrestrial artiodactyls, similar to small deer. The transition from land to water is documented by a series of intermediate fossils, many of.
Dolphins are also often longer, averaging about six to 12 feet in length, where porpoises only reach a maximum seven feet in length. The smallest toothed whale is the vaquita, an extremely endangered species that only grows to about four feet and 120 pounds.
Our advice also highlights that, in terms of dolphins and porpoises, protection measures will only be effective when they have been applied over a longer period of time. As the EU can only implement emergency measures for a period of six months (with a possible six month extension), ICES advises that these short-term emergency measures can only be considered as a first step toward longer term.
Dolphin is a 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), Iniidae (the New World river dolphins), and Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species named as dolphins.
The Bottlenose dolphin is one of the most common dolphin species found in most of the world's oceans, including the UK waters. These intelligent mammals often travel in groups called 'pods' and interact with their social and physical environment using 'echolocation'. A healthy number of bottlenose dolphins in our waters can mean a healthy ocean and a stable, balanced ecosystem.
