Baleen whales take big gulps of water when.

How do huge whales feed when they don't have teeth. The right whales filter feed by skimming the water which involves swimming along the surface of the water with an open mouth. Grays are the only bottom feeding whales. The sperm whale is the most evolutionarily modified of the toothed whales.

Rorqual whales are gulpers which means they take big swallows find the food and filter out all the excess water. For example the Blue Whale can hold up to 2200 pounds of food before it is a top capacity. Since gray whales have no teeth they capture and strain their baleen which hangs from the roof of the mouth.

Sperm whales have teeth in their bottom jaw but none on the top so they cannot bite or chew. One thing they have in common is that they do not use their teeth to chew their food. As the whale swims in comes water rich with the plankton that live on the oceans surface.

The Toothed whale with the biggest full set of teeth is the sperm whale who has around 40 to 52 cone-shaped teeth that are 4-8 inches in length. When they feed a whale dives to the bottom rolls on its right side and gulps mouthfuls of mud from the bottom. The more aggressive predators are the Tooth Whales and they eat larger fish and other aquatic life.

Baleen whales have very small throats in contrast to toothed whales. Toothed whales such as killer whales and pilot whales are equipped with a large set of teeth as their name implies. Whales need to eat everyday because they are so huge and need so much food.

Mysticeti whales dont have any teeth at all instead they have something called baleen. Some toothed whales feed on squid. They use the teeth for the killing process only.

These whales are known as baleen whales Look closely. For this reason these whales usually hunt for small animals that they can swallow easily. These whales can eat up to 8000 lbs of krill each day.

An early initial assumption Peredo said was that ocean-dwelling mammals must have needed teeth or baleen to eatbut several living whales contradict that idea. All whales are actually broken down into two categories or suborders which are known as the toothed whale and baleen whale suborders. Baleen whales dont have teeth they have something called baleen plates.

Sperm whales attain sexual maturity at 7 to 13 years of age and physical maturity at 25 to 45 years and have been recorded to live as long as 62 years. Baleen whales swim through the water with their mouth. A single blue whale can consume up to 40 million of them in a single day.

Some toothed whales use their tongues as pistons to suck in the food using their teeth more socially than for feeding. If you think about a blue whale for example up to 150 tons sometimes as much as 100 feet long even if you have baleen if youre going to get enough energy for an animal that large when you do lunge when you do take in big gulp of seawater you have to have massive quantities of prey in order to actually make that efficient. With the absence of teeth baleen whales do not chew their prey.

They feed primarily on cephalopods including the giant squid Architeuthis dux. Baleen is made of a substance similar to your fingernails with a row of fringe along one side. Although all toothed whales have teeth the number size and position of their teeth varies from species to species.

These whales have a diet that includes schooling fishes squid and marine mammals such as seals. Blue whales and other baleen whales have what are called baleen plates in their mouths filters that push out the water as the whales swallow enormous congregations of these tiny creatures. Narwhals only teeth are their long tusks which they do not use for feeding.

They have figured out a different way to eat. During the summer months the blue whale which is a baleen whale can eat up to 4 of their body weight per day. Instead they have baleen plates hanging from their upper jaw.

These plates hang from inside the top of a whales mouth like giant combs. In the case of killer whales also known as orcas. Toothed whales as the name suggest have teeth which they use to attack capture and in some cases chew or tear apart their prey so that they can swallow and better digest their food.

For example the average size of blue whale prey is less than two inches. Even though these larger whales do have teeth most of them dont use them to tear apart their food. Believe it or not some species of whale do in fact have teeth.

Instead they swallow the animals whole. Think of baleen as a coffee filter or a kitchen strainer you can ask your parents to see one if you dont know what that is you can play with it a bit if you like to see how things like dried rice get stuck inside the strainer but water can still pass through. Some species eat other whales and dolphins.
