Toothed Whales | Odontoceti

Odontocetes are toothed whales classified under Cetaceans that include mammals such as the sperm whale, beaked whales, porpoise, and dolphins. Male and female Odontocetes show distinct sexual dimorphism. Odontocetes are acknowledged to have well-developed hearing senses with some species being very intelligent. They also have conical teeth and a layer of fat beneath their skin for keeping them warm while in cold waters. Additionally, most species of the Odontocetes are sociable with smaller Odontocetes like the dolphins kept in captivity for scientific research and entertaining people by doing tricks. Others are followed or observed in the ocean in an activity called whale watching.

What do dolphins eat?

A dolphin’s diet typically consists of a variety of fish, squid, shrimp, jellyfish, and octopuses. Their diet also depends on the species of the dolphin (there are more than 40 species of dolphin), where the dolphin lives, and the other wildlife that lives around them.

How long do dolphins live?

The life expectancy of a dolphin is affected by their habitat, geography, diet, level of endangerment, health, social structure, and species. Dolphins are able to live for an average of 20 years, and female dolphins tend live longer than males. Dolphins that live in captivity tend to have shorter lifespans than those in the wild.

Where do dolphins live?

Dolphins are able to live in all of the world’s oceans and in some rivers. Not all species of dolphins are able to live in every environment, except for the bottlenose dolphin who is able to live in almost every ocean except for the Arctic and Antarctic ocean. Most dolphins prefer tropical and temperate waters since they are warm-blooded mammals.

Amazon River Dolphin (Inia geoffrensis)
Measured comparison illustration of the size of a Amazon River Dolphin to a typical person and similar species

The Amazon River Dolphin or boto or bufeo or pink dolphin are freshwater toothed whales under the family Iniidae existing mainly in the Amazon basin and also in some rivers of South America. Botos have a look of their own: usually pink with males being pinker and bigger than females. They have small dorsal fins, plump bodies, long skinny snouts, and small eyes. Botos love solo life, however, can also be found in small groups. Pink dolphins are active all day, inquisitive with large paddle-shaped flippers and lithe and maneuverable bodies. Also, pink dolphins have been associated with legends and also featured in mythology.

Amazon River Dolphins have a total length between 6.5’-8.5’ (1.98-2.59 m), body height of 14”-19” (37-48 cm), and width of 22”-29” (56-74 cm). The typical weight of the Amazon River Dolphin is in the range of 331-408 lb (150-185 kg). Amazon River Dolphin have lifespans between 25-30 years.

Baiji (Lipotes vexillifer)
Comparison drawing of the Baiji compared to other similar species and a person

Baijis are functionally extinct toothed whales under the family Lipotidae that populated the freshwater of the mighty Yangtze River. These animals could be found in groups of up to 16 and loved to surface but were shy and quiet, often avoiding boats. The Baiji was identified by a smaller head with a slender long beak upturned slightly at the tip. They also had small eyes with low vision, smaller triangular dorsal fins positioned halfway along their backs, and broadly rounded flippers on thier stocky bodies. Additionally, Baijis featured in Chinese folklore, relied on sonar for navigation, socializing, and showing emotions and believed to live up to 24 years. Baijis had a pale blue or grey coating on their backs and also spotted a white ventral belly side.

Baijis have a total length between 4.5’-8.5’ (1.37-2.59 m), body height of 11”-20” (27-52 cm), and width of 13”-24” (32-61 cm). The typical weight of the Baiji is in the range of 287-375 lb (130-170 kg). Baiji have lifespans between 24-30 years.

Indus River Dolphin (Platanista minor)
Scale illustration of an average Indus River Dolphin compared to a human and similar species

The Indus river dolphin is an endangered marine mammal found in the river of Pakistan and classified under the family Platanistidae. It is identified by a long sharp snout, visible teeth even with a closed mouth, and relies mostly on echolocation for navigation and hunting unlike other cetaceans because it has very low vision. The Indus river dolphin can swim on its side besides having a dorsal fin resembling a small triangular lump. Their flippers and tails are thin and large and the body is brown in color. They also migrate seasonally either downstream or upstream and are usually killed by humans because of competition for fish.

Indus River Dolphins have a total length between 7’-8.17’ (2.13-2.49 m), body height of 16”-19” (42-49 cm), and width of 19”-22” (48-56 cm). The typical weight of the Indus River Dolphin is in the range of 154-243 lb (70-110 kg). Indus River Dolphin have lifespans between 18-26 years.

Striped Dolphin (Stenella coeruleoalba)
Measured comparison illustration of the size of a Striped Dolphin to a typical person and similar species

The Striped dolphin is an extremely curious, active, and fast-moving mammal under the family Delphinidae widely distributed in all temperate and tropical oceans worldwide. The animals are usually small, very streamlined, and flashy with the grey strips that run along its body being the most distinct feature. Like other dolphins, the Striped dolphin is very social, often moving in large pods and at top speed. These animals love to be at the surface of the water where they display amazing acrobatics and engage in leap and high jumps. They are likewise killed in large numbers for their meat and trade to dolphinariums.

Striped Dolphins have a total length between 7.17’-8.5’ (2.19-2.59 m), body height of 16”-18” (41-47 cm), and width of 20”-23” (51-59 cm). The typical weight of the Striped Dolphin is in the range of 198-331 lb (90-150 kg). Striped Dolphin have lifespans between 45-58 years.

Pacific White-Sided Dolphin (Lagenorhynchus obliquidens)
Measured comparison illustration of the size of a Pacific White-Sided Dolphin to a typical person and similar species

The Pacific white-sided dolphin is an energetic and acrobatic dolphin grouped under the family Delphinidae. They prefer the deep offshore waters of the North Pacific ocean. These vertebrates are a genuine beauty with their sturdy bodies covered in shades and tones of black, white, and silvery colors. They also spot stubby beaks, tall, curved bi-colored distinctive dorsal fins, and large rounded flippers. They are very showy, social, love traveling in large groups, and not frightened to hang out with other species or even approaching boats. Pacific white-sided dolphins are also kept in dolphinaria for scientific research and marine theme park shows.

Pacific White-Sided Dolphins have a total length between 5.5’-8.17’ (1.68-2.49 m), body height of 13”-19” (33-49 cm), and width of 16”-23” (40-59 cm). The typical weight of the Pacific White-Sided Dolphin is in the range of 298-441 lb (135-200 kg). Pacific White-Sided Dolphin have lifespans between 35-46 years.
