Toothed Whales | Odontoceti

Description
Description

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.

Anatomy
Anatomy

Toothed whales (Odontoceti) have streamlined bodies built for efficient swimming. Their strong tails, or flukes, move up and down, propelling them forward. Unlike their baleen counterparts, they have teeth used for catching prey. A blowhole on top of their head allows them to breathe while mostly submerged.

These creatures use echolocation for navigation and hunting: they emit sound waves that bounce back, helping them "see" underwater. Their sophisticated brains and complex vocal cords allow for a range of sounds, aiding in communication. With sharp eyesight in water, and a less developed sense of taste and smell, they're well-adapted marine predators.

Human Interaction
Human Interaction

Toothed whales (Odontoceti) have a multifaceted relationship with humans that spans centuries. Historically, they've been hunted for their oil, meat, and teeth, leading to population declines in some species. In modern times, many societies revere these cetaceans, with dolphin-watching and whale-watching becoming popular ecotourism activities.

However, they still face threats from human activities, including ship strikes, pollution, and bycatch in fishing nets. Conservation efforts have been amplified, leading to protections like the Marine Mammal Protection Act and global moratoriums on whaling. While many species show signs of recovery, others, especially smaller cetaceans, remain critically endangered due to persistent human-induced threats.

Common Questions
Common Questions
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.

Finless Porpoise (Neophocaena sunameri)
Measured comparison illustration of the size of a Finless Porpoise to a typical person and similar species

Finless porpoise inhabits most of the areas or water of the Korean peninsula, Jiuduansha, and the Yellow and East China seas. They fall under the family Phocoenidae with the most distinct characteristic being lack of a true dorsal fin. These animals have an unusually steeper forehead, moderately large flippers, and bodies in uniform bright grey color. Compared to other porpoises, they are rarely social, prefer solitary or small schools, less energetic, and less showy, but can show tail stands and acts of breaching. Finless porpoises also prefer coastal waters, putting them at risk of death from human activity and entanglement in gill nets.

Finless Porpoises have a total length between 6.25’-7.5’ (1.91-2.29 m), body height of 14”-17” (36-43 cm), and width of 21”-25” (54-64 cm). The typical weight of the Finless Porpoise is in the range of 66-159 lb (30-72 kg). Finless Porpoise have lifespans between 10-20 years.

Irrawaddy Dolphin (Orcaella brevirostris)
Measured comparison illustration of the size of a Irrawaddy Dolphin to a typical person and similar species

The Irrawaddy dolphin is distinguishable from other dolphins by their very expressive face. These oceanic dolphins are grouped under the family Delphinidae and prefer sea coasts, river outlets, and shallow waters of Southeast Asia, Bay of Bengal, and Indonesia. They are sociable, existing in small groups, slow swimmers, and may occasionally spit spout of water from their mouths. Irrawaddy dolphins lack beaks but are highly recognizable from their charismatic rounded face that makes them resemble baby belugas. Other traits include small dorsal fin but long and larger flippers and greyish body, though their belly is lighter. Irrawaddy dolphins also love to engage in cooperative fishing with local fishermen.

Irrawaddy Dolphins have a total length between 5.92’-9’ (1.8-2.74 m), body height of 14”-21” (36-54 cm), and width of 15”-23” (39-59 cm). The typical weight of the Irrawaddy Dolphin is in the range of 198-441 lb (90-200 kg). Irrawaddy Dolphin have lifespans between 15-30 years.

Pygmy Sperm Whale (Kogia breviceps)
Comparison drawing of the Pygmy Sperm Whale compared to other similar species and a person

Pygmy sperm whales also called lesser sperm whales or lesser cachalot or short-headed sperm whales are grouped under the family Kogiidae. They are rather slow swimmers and prefer to sink when they want to move instead of rolling like other cetaceans. Pygmy sperm whales are sighted on warm, deep tropical and temperate subtropical oceans. These animals are small, have shark-like heads, small and hooked dorsal fins with ”false gills” visible behind each eye. The animals are less social, preferring solo life, or living in pairs. They also show the inconspicuous movement of rising out of the water gently to remain stationary on the surface with a little splash. The Pygmy sperm whale also ejects a reddish-brown fluid to throw off potential attackers.

Pygmy Sperm Whales have a total length between 10’-11.5’ (3.05-3.5 m), body height of 22”-25” (56-65 cm), and width of 22”-24” (56-62 cm). The typical weight of the Pygmy Sperm Whale is in the range of 683-992 lb (310-450 kg). Pygmy Sperm Whale have lifespans between 17-23 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.
