Diets and habitats
- Bottlenose dolphins, scientifically known as Tursiops, may not resemble seals physically, but they share similarities in their diets and habitats. These highly intelligent marine mammals have a diet similar to seals and feed on squid, shrimp, and fish. Bottlenose dolphins are among the most commonly spotted dolphins and are easily recognizable.

Swimming speed and duration are closely tied: high-speed swimming probably lasts only seconds, while low-speed swimming may last for long periods of time. Bottlenose dolphins routinely swim at speeds of 4.6 to 10.2 feet per second (3.14 to 6.95 miles/hour; 5.04 to 11.19 km/hour) with a mean speed of 4.9 to 5.6 f/s (3.34 to 3.82 miles/hour; 5.4 to 6...
A dolphin breathes through a single blowhole on the top surface of its head. The blowhole is covered by a muscular flap, which provides a watertight seal. 1. A dolphin holds its breath while below water. 2. The dolphin opens its blowhole and begins to exhale just before reaching the surface of the water. To open the blowhole, the dolphin contracts ...
Bottlenose dolphins generally do not need to dive very deep to catch food. 1. Depending on habitat, most bottlenose dolphins regularly dive to depths of 3 to 46 m (10 to 150 ft.). The average dive duration of coastal bottlenose dolphins ranges from 20 to 40 seconds. Mean dive duration of 25.8 seconds. 2. They are capable of diving to greater depths...
Like other mammals, dolphins maintain a constant body temperature. A dolphin's core body temperature is about 36° to 37°C (96.8° to 98.6°F), about the same as that of a human. Dolphins have several thermoregulatory strategies to retain or release heat. 1. Decreased surface-to-volume ratio. 1.1. The dolphin's fusiform body shape and reduced limb siz...
When studying sleep in bottlenose dolphins, researchers found that dolphins spent about 33% of each day sleeping. Researchers have shown, through both observations and electro-physiological studies that deep sleep in bottlenose dolphins and other whales may occur in only one brain hemisphere at a time.
Bottlenose dolphins can thrive in many environments and feed on a variety of prey, such as fish, squid, and crustaceans (e.g., crabs and shrimp). They use different techniques to pursue and capture prey, searching for food individually or cooperatively.

May 3, 2019 · In 2017, Russian state television reported that the country was experimenting with using beluga whales, bottlenose dolphins, and several species of seals to guard entrances to naval bases,...
There are two species of bottlenose dolphin: the common bottlenose dolphin (Tursiops truncatus) and the Indo-Pacific bottlenose dolphin (Tursiops aduncus). Where do bottlenose dolphins live? Bottlenose dolphins are found in warm and temperate seas worldwide, except in the Arctic and Antarctic Circle regions. How big are bottlenose dolphins?
Oct 4, 2024 · bottlenose dolphin The common bottlenose dolphin (Tursiops truncatus) is found worldwide in warm and temperate seas. Bottlenose dolphins reach an average length of 2.5–3 metres (8–10 feet) and weight of 135–300 kg (300–650 pounds). Males are generally larger than females.
Bottlenose dolphins are arguably the most recognized small cetaceans, but can be hard to distinguish from other wild dolphins. These animals are counter-shaded: blackish, slate, gray, brown or bluish on top, and lighter on the sides; and whitish or paler pinkish gray underneath.
