The calf feeds on milk from the teats of its mother. Unlike human babies, however, dolphins do not have the lips needed to suck the teats. Also they could not breathe under water if they were able to suck. To solve these problems, the mother squirts milk into her offspring's mouth by contracting muscles.

The young dolphin then goes up to the surface to breathe and then comes down for more. Dolphin milk has 6 times more protein and is much more fattening than human milk.

It allows the baby dolphin to increase its weight 2 to 3 times faster than a human baby does during the first six months. Suckling goes on for about a year and a half. After six months, the baby occasionally takes solid food. Dolphins are very social organisms. Common dolphins are seldom alone. They travel together, they eat together, they even breathe together!

The whole school can all be in the air at one time. Schools can contain as many as to , individuals. Common dolphins are the most abundant and wide spread species of dolphins.

In higher latitudes, when the first storms of fall move over the waters, females and their young assemble into large companies to face the vigors of winter. They depend on their large numbers to find food and on their speed and caution for protection. Males live apart from these large herds of females. Although they remain in the same area, they stay a considerable distance away until the warmer spring season approaches.

Further separation of the sexes occurs in nursery schools of pregnant and nursing females. Dolphins are playful creatures.

The common dolphin is no exception. They are both active and boisterous. They do various flips and somersaults. They leap with their whole bodies out of the water. Smaller dolphins sometimes leap vertically. Common dolphins play with one another in a somewhat rough fashion, rushing towards one another.

The favorite activity of the common dolphin, however, is bow-riding. They ride off ships and the pressure waves created by whales. They may stay with the vessel, jumping and playing, for a period of up to several hours.

Common dolphins are also a very affectionate species. They care for their sick by using their fins to keep the ailing dolphin afloat so it may breathe. Moreover, they make friends with the members of their groups and show obvious emotions towards them.

In captivity, two males who were separated became very excited when reunited. Also when members of the group are separated or die, dolphins exhibit emotions of sadness and seem to be pining away for their playmates. Within the groups, adults act as teachers to the young. Younger dolphins are disciplined when proper manners are not performed. In addition, mothers in the groups share responsibilities in taking care of the young. They take turns watching over those that are too active.

Common dolphins, as with other cetaceans, are a very vocal species. They communicate with each other using two voices--one being for navigation and location and the other being for social communication. The voice can be described as whistle-like pulse sounds. Variations in loudness, speed, and pitch convey different messages.

In captivity, attempts to teach dolphins to speak are made. Common dolphins, however, are not easily trained despite their friendliness. In captivity, common dolphins are very uncharacteristically shy. Voices can also be used as aids in "sight. Vision is often difficult, espcially in dark and murky waters. Common dolphins have very few enemies. Those they do have to worry about are sharks and killer whales.

Delphinus delphis feed on small fish as well as squid and octopus. Small fish include young herring, pilchard, anchovies, nocturnal hake, sardines, small bonito, as well as sauries. Individual dolphins eat up to 18 to 20 pounds of fish per day. Groups of common dolphins all feed at the same time during the night or day. They are sometimes joined by bands of bottlenose or white-sided dolphins. These feeding forays can last up to an hour.

During these, each dolphin rushes to the center of the school the group has been pursuing and tries to seize as many fish as possible, which it swallows whole. Common dolphins have also been known to dive below schools and drive them to the surface. They push their prey completely out of the water and catch them in midair.

Common dolphins are a very helpful and friendly species. They have been known to rescue humans. Its coloring pattern features a dark dorsal area and a white ventral region. Along the sides, there is a thick band of light color that does not become white. Distinctive characteristics. The shape of the coloring pattern is its most distinctive sign. To distinguish it from Delphinus capensis, which is very similar, the size of the beak is the main feature that makes them different.

This dolphin inhabits all tropical, subtropical and warm seas of the world, especially in the Pacific and Atlantic oceans. In the south of Australia. It dwells along the continental slope, in waters with depths ranging from to 2, meters and has a preference for the marine areas where the upwelling occurs and for the seamounts and escarpments. Small fish such as herring, sardines, hake, and anchovy are an important part of their diet, also cephalopods which include octopus and squid. They consume crustaceans to a lesser extent.

In total, an adult dolphin consumes more than 8 kilograms of food per day. It feeds mostly at night, and it has cooperative hunting strategies. When a group of dolphins is looking for food, each member submerges for up to 8 minutes to detect prey. If they are successful and find a school of fish or any other prey, they can perform two hunting strategies:.

Before the prey escapes, they catch it. They prefer to feed at night because they wait for the prey that migrates to the surface every night. The whole hunting process takes about 1 hour, and they can submerge up to meters deep during the process. It is very rare to find a Short-beaked common dolphin alone.

These dolphins are very social which can be seen in all their daily activities like eating, traveling and even breathing. The pods are very numerous and are composed of 10 to individuals but, as in other species, they usually associate with other pods forming large temporal groups of thousands of dolphins.
