Baleen whales feed mainly on plankton or small fish which they filter with their baleen plates. Toothed whales, on the other hand, rely on sharp teeth to catch larger prey such as squids and octopuses. Both types of whales can be found in all of the world’s oceans, from polar waters to tropical seas.

Baleen whales, also known as mysticetes, are a group of marine mammals that belong to the order Cetacea. They are characterized by their baleen plates, which are comb-like structures made of keratin that hang from their upper jaws and are used to filter small organisms such as krill, plankton, and small fish from seawater.
There are 15 species of baleen whales, including the blue whale, humpback whale, gray whale, and minke whale. They can be found in all the world’s oceans, from the Arctic to the Antarctic, and from the coastal waters to the open ocean.
Baleen whales are some of the largest animals on Earth, with the blue whale being the largest animal to have ever lived. They are also known for their complex vocalizations, which can be heard over long distances and are thought to play a role in communication, navigation, and mate selection.
Baleen whales are an important part of marine ecosystems, and their feeding behavior plays a crucial role in regulating the populations of small organisms in the oceans. However, they are also vulnerable to human activities such as hunting, pollution, and climate change, and several species are currently endangered or threatened.

Toothed whales, also known as odontocetes, are a group of marine mammals that belong to the order Cetacea. Unlike baleen whales, they have teeth instead of baleen plates in their mouths. Toothed whales are predators that feed on fish, squid, and other marine animals, and they use echolocation to navigate and locate their prey.
There are around 70 species of toothed whales, including the orca (also known as the killer whale), sperm whale, beluga whale, and bottlenose dolphin. They can be found in all the world’s oceans, from the Arctic to the Antarctic, and from the coastal waters to the open ocean.
Toothed whales are highly intelligent and social animals, with complex communication and social structures. They are also known for their acrobatic displays and their ability to swim at high speeds and depths.
Toothed whales are an important part of marine ecosystems, and their hunting behavior plays a crucial role in regulating the populations of their prey species. However, they are also vulnerable to human activities such as hunting, pollution, and habitat destruction, and several species are currently endangered or threatened.
What is baleen?
Baleen is a keratinous substance that hangs down from the roofs of the mouths of certain filter-feeding marine mammals. It is used to strain small prey items from large volumes of water. Baleen whales, such as blue whales and humpback whales, have baleen plates in their mouths instead of teeth. These plates are fringed with long, thin strands of baleen that act like a sieve to trap small fish and krill while allowing large amounts of seawater to pass through. Toothed whales, on the other hand, have teeth that they use to capture and eat their prey whole.
Baleen whales Vs. Toothed whales
Baleen whales and toothed whales are two distinct groups of marine mammals that belong to the order Cetacea. The main differences between the two groups are:
- Mouth structure: Baleen whales have a series of comb-like baleen plates hanging from their upper jaw that they use to filter small organisms from seawater. Toothed whales, on the other hand, have teeth in their mouths that they use to catch and eat their prey.
- Feeding behavior: Baleen whales are filter feeders that strain small organisms like krill and plankton from seawater using their baleen plates. Toothed whales are active hunters that use echolocation to locate and catch their prey, which includes fish, squid, and other marine animals.
- Size: Baleen whales tend to be larger than toothed whales, with the blue whale being the largest animal to have ever lived. Toothed whales vary in size, from the small harbor porpoise to the larger sperm whale.
- Vocalizations: Both baleen whales and toothed whales use sound for communication and echolocation. However, toothed whales have more complex vocalizations and use echolocation to locate their prey.
- Social behavior: Both baleen whales and toothed whales are social animals that live in groups or pods. However, toothed whales tend to be more social and have more complex social structures than baleen whales.
The main differences between baleen whales and toothed whales are their mouth structure, feeding behavior, size, vocalizations, and social behavior.
What is the difference between Mysticeti and Odontoceti?
Mysticeti are the filter-feeding whales, and include the largest animals on Earth. They have long, flat skulls with large mouths, and lack teeth. Instead of teeth, they have baleen plates made of keratin that hang down from their upper jaws. These plates act like a sieve, allowing the whale to take in large amounts of water and filter out tiny prey items such as krill and zooplankton.
Odontoceti are the toothed whales, which includes all species of dolphin, porpoise, beluga whale, and sperm whale. These whales have conical teeth that they use to capture fish and squid. They also use echolocation to navigate and find prey in dark or murky waters.
Why do whales have baleen instead of teeth?
There are a few key reasons why baleen whales have baleen instead of teeth. For one, baleen helps these whales filter-feed on small organisms in the water. This is a more efficient way for them to feed than having to chew their food like toothed whales do. Additionally, baleen is made of keratin, which is much stronger than tooth enamel. This means that it can withstand the immense pressure that comes with living in the deep ocean. Finally, whales with baleen tend to be larger than those with teeth, and thus need a bigger mouth opening. Having baleen plates instead of teeth allows them to open their mouths extremely wide without risking injury.
Is a blue whale baleen or toothed?
Baleen whales are filter feeders that use baleen plates to strain food from the water. They are the largest animals on Earth and include blue whales, humpback whales, and right whales. Toothed whales are predators that hunt fish and other marine mammals. They use their teeth to tear apart their prey. Toothed whale species include sperm whales, orcas, and dolphins.
Are orcas toothed or baleen?
Orcas are toothed whales. They have a large, prominent dorsal fin and sleek black-and-white coloration. Orcas are highly intelligent and social creatures, living in pods of up to 40 individuals. They use echolocation to communicate and hunt for fish, squid, and seals.
Are dolphins a type of whale?
Dolphins are often referred to as “whales,” but they are actually a type of oceanic dolphin. There are over 40 species of dolphin, and they are found in all the world’s oceans. They range in size from the 1.7m (5.6 ft) long Maui’s Dolphin to the 9.5m (31 ft) long Orca.
Dolphins are highly intelligent and social animals, and they have been known to help humans in need. They use echolocation to navigate and hunt, and they communicate using a variety of sounds and body language.
Most dolphins eat fish, squid, and other small marine creatures. Some species, such as the Orca, also feed on larger prey, including seals, sea lions, and even whales.
Is baleen similar to human teeth?
Baleen is a material found in the mouths of baleen whales. It consists of long, thin plates that hang down from the roof of the mouth and filter food from the water. Baleen is made up of keratin, the same protein that makes up human hair and nails.
Baleen whales have two sets of teeth: one set in the upper jaw and one set in the lower jaw. The teeth in the upper jaw are used for chewing food, while the teeth in the lower jaw are used for gripping prey. The number of teeth varies between species, but most baleen whales have between 100 and 400 teeth.
The main difference between baleen and human teeth is their purpose. Human teeth are used for biting and chewing food, while baleen is used for filters tiny organisms out of the water. Baleen is also much longer than human teeth; it can grow up to 3 feet (1 meter) in length!
