When feeding, Common bottlenose dolphin pods often work as a team to harvest schools of fish, though they also hunt individually. They engage both in aggressive behavior, such as biting, ramming, and tail slapping and behavior of bonding and acceptance behavior, such as rubbing and stroking. Typically living in groups ranging from just a few individuals to more than 100, they form several types of groups, which include nursery groups, juvenile groups, and groups of adult males. Offshore dolphins, however, are adapted to cooler, deeper waters.īottlenose dolphins are very social animals. They can be found in harbors, bays, lagoons, estuaries, and occasionally in rivers.
The coastal dolphins appear to adapt to warm, shallow waters. Some populations live offshore and some inshore. Some populations remain in one area, while others migrate extensively. These dolphins have 18 to 28 conical-shaped teeth on each side of each jaw.Ĭommon bottlenose dolphins are found in all of the world's seas, both tropical and temperate. Sometimes they have spots on their bellies and a stripe from the eye to the base of the flipper.
This coloring makes it hard to see them, from both above and below. These dolphins are usually black to a light gray, with white bellies, which are sometimes slightly pink. The dorsal fin, positioned near the middle of the back, is tall and curved. They feature front flippers, flukes, and a dorsal fin, which they use for swimming.
