What are some cool facts about humpback whales?

Fun Facts About Humpback Whales

• Humpback whales grow up to 60 feet (18.3 m) long and 80,000 pounds (36.3 metric tons).
• Humpback whales can live for 80 to 90 years.
• Humpback whales have some of the longest migrations of any mammal with some populations swimming 5,000 miles (8,047 km) between breeding and feeding grounds.

What do humpback whales use their flippers for?

Humpback whales use their flippers to create a barrier that traps gathered prey, which they can then usher towards their mouths by swatting the water.

Can a whale survive without a dorsal fin?

In some whales (e.g. right whales and narwhals), the dorsal fin has disappeared altogether. In other species (e.g. blue and sperm whales), this fin is so small that it no longer really serves any purpose.

What is the whale flipper?

In animals with two flippers, such as whales, the flipper refers solely to the forelimbs. The dorsal structure on cetaceans is called the “dorsal fin” and the large cetacean tails are referred to primarily as flukes but occasionally as “caudal fins”; neither of these structures are flippers.

What is the difference between flippers and fins?

Fins have no true bones or skeletal structure within and are composed primarily of cartilage. A flipper has a bone structure as well as cartilage, joints, and tendons.

What animal was Flipper?

Flipper is a bottlenose dolphin and the companion animal of the Ricks family.

Is human arm and whale flipper analogous or homologous?

For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. Some structures are both analogous and homologous: the wings of a bird and the wings of a bat are both homologous and analogous.

Is human arm and alligator homologous?

For example, a human arm and alligator forelimb both are having the same homologous structures. The human arm classified into the upper arm and forearm. The forearm contains two bones, one is Radius and the second one is Ulna. Alligator forelimb classified into Radius, Ulna, and humerus.

What is the strongest evidence of evolution from a common ancestor?

Similar DNA sequences are the strongest evidence for evolution from a common ancestor.

Why are wings analogous?

Bird and bat wings are analogous — that is, they have separate evolutionary origins, but are superficially similar because they have both experienced natural selection that shaped them to play a key role in flight. Analogies are the result of convergent evolution.

What animals are analogous?

Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish. Plants and other organisms can also demonstrate analogous structures, such as sweet potatoes and potatoes, which have the same function of food storage.

Are bat wings analogous to bee wings?

A great example of analogous structures are a bat’s wing and a bee’s wing. Bats and bees do not share common ancestry, so the structures cannot be homologous. Both bat wings and bee wings serve a common purpose – helping bats and bees fly! The structures look similar on the outside, too.

Are platypus and duck bills homologous?

Although the duck-billed platypus is an egg-laying mammal which is a behavioral trait that evolved dominantly in birds, it is not related to the avian family by any other characteristic. A duck can lay eggs, fly, swim and although has the same bill as the Platypus, however the duck is from reptile origin.

What are analogous structures for kids?

Organisms that have evolved along different paths may have analogous structures—that is, anatomical features that are superficially similar to one another (e.g., the wings of birds and insects). Although such structures serve similar functions, they have quite different evolutionary origins and developmental patterns.

What are analogous organs examples?

Analogous organs are the opposite of homologous organs, which have similar functions but different origins. An example of an analogous trait would be the wings of insects, bats and birds that evolved independently in each lineage separately after diverging from an ancestor without wings.
