How do whales filter feed?

Asked by: Stacy Martin

Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out, and animals such as krill are filtered by the baleen and remain as a food source for the whale.

How do blue whales filter feed?

Blue whales are filter-feeders, using baleen plates in the mouth made of keratin, also found in people’s fingernails, to strain krill from ocean water. When lunge-feeding, the whale accelerates and opens its mouth, taking in a volume of prey-laden water up to 130 percent of its weight.

How does filter-feeding work?

Filter feeding is a method of aquatic feeding in which the animal takes in many small pieces of prey at one time. As opposed to predators who seek out specialized food items, filter feeding is simply opening up your mouth and taking in whatever happens to be there, while filtering out the undesirable parts.

How does filter-feeding work in whale sharks?

They open their mouths wide and swim through the water using their horns to traffic the plankton into their mouth. Animals that eat by filtering the water and sifting plankton. Are called filter

How do whales trap feed?

Trap-feeding is where some Humpbacks set a trap for juvenile herring when juvenile herring are in small, diffuse schools. The fish then collect near, or in, the mouth of the Humpback to escape predation by diving birds (most often Common murres and Rhinoceros Auklets).

How do filter feeders get their food?

Filter feeders are a sub-group of suspension feeding animals that feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure.

Why whales are called filter feeders?

Whales called as filter feeders because they used to filtered their food through baleen plates. they suction water into their mouths at high velocities while their body remains stationary. The food along with water moves through the filtering pads or baleen plates that covered the entrance of their throat.

How do whales bubble net feed?

Bubble-net feeding is when whales deliberately blow bubbles from their noses to encircle their food — krill and fish — like a net, concentrating their prey into a tight ball. Then, the whale or group of whales swim together from beneath, rise to the surface opening their mouths, and gulp up their prey.

How do whales catch fish?

Explainer: What is a whale? Humpbacks (Megaptera novaeangliae) often feed by lunging with their mouths open to catch any fish in their path. Sometimes, the whales will first swim upward in a spiral and blow bubbles underwater. This creates a circular “net” of bubbles that makes it harder for fish to escape.

Where do whales bubble net feed?

To bubble-net feed, whales dive deep below schools of fish and use bubbles blown from their blowholes to stun and trap fish closer to the surface.

What is the process of bubble netting?

Bubble netting is a way that the whales are able to capture these speedy schooling fishes one whale dies down and deploys a ring of bubbles from its blowhole.

How do hump back whales feed?

Humpback whales feed on shrimp-like crustaceans (krill) and small fish, straining huge volumes of ocean water through their baleen plates, which act like a sieve. The humpback whale gets its common name from the distinctive hump on its back.

Why do whales make bubble rings?

It’s been established that humpbacks release large quantities of bubbles in rings out of their blowholes to corral schools of krill and small fish, which makes hunting the one to one-and-half tons of food they need to eat each day much easier.

What is it called when a whale blows water?

Spouting / Blowing



When a cetacean comes to the surface to breathe, it releases a lot of air, called its spout (or blow), when it exhales. The breath is made of warm air and water droplets.

Do whales dance?

One of the most profound experiences to witness on the Silver Bank is a courtship interaction nicknamed “dancing.” As one of the final stages of courtship before mating, the whales provide an amazing performance as they twist, twirl, roll, circle and dive around each other, and sometimes us.

How do whales make bubbles?

While other baleen whales feed by swimming rapidly forward, humpbacks have large flukes (lobed end of the whale’s tail) relative to their size, providing greater thrust for the quick maneuvers that create bubble nets.

What is it called when whales feed?

Bubble-net feeding is a feeding behavior engaged in by humpback whales and Bryde’s whales. It is one of the few surface feeding behaviors that humpback whales are known to engage in. This type of feeding can be done alone or in groups with as many as twenty whales participating at once.

What is lunge feeding?

Lunge feeding is a behavior during which a whale consumes a large quantity of prey and water after a high-speed horizontal or vertical propulsion, followed then by the removal of water through closed-mouth filtration (Goldbogen et al 2013).

How do blue whales eat?

They feed almost exclusively on krill, straining huge volumes of ocean water through their baleen plates (which hang from the roof of the mouth and work like a sieve). Some of the biggest individuals may eat up to 6 tons of krill a day. Blue whales are found in all oceans except the Arctic Ocean.

Do whales eat humans?

Experts noted that whales do not eat people, but consume small aquatic lifeforms like fish, squid and krill.

How do whales sleep?

Observations of bottlenose dolphins in aquariums and zoos, and of whales and dolphins in the wild, show two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal.

Can blue whales eat humans?

Despite their large size, blue whales do not eat people. Actually, they couldn’t eat a person no matter how hard they tried to. Even though these marine mammals are the largest animals globally, several factors prevent them from eating a person.

Can a man survive inside a whale?

While the veracity of the story is in question, it is physically possible for a sperm whale to swallow a human whole, as they are known to swallow giant squid whole. However, such a person would be crushed, drowned or suffocated in the whale’s stomach.

Has anyone survived being swallowed by a whale?

Massachusetts commercial lobster diver Michael Packard thought he was going to die after a humpback whale swallowed him into its mouth in 45 feet of water off Cape Cod. But he survived.
