How many ribs does a pilot whale have?

Pilot whales typically have 13-16 pairs of ribs, for a total of 26-32 individual ribs.

What Arctic animals eat seaweed?

Arctic animals that eat seaweed include walruses, some species of seals, and certain species of fish such as the Arctic cod and the Arctic char. These animals rely on seaweed as a source of food and nutrients in their cold, harsh environment.

What are the harmless sea creatures?

Some examples of harmless sea creatures include jellyfish, sea stars, sea anemones, and certain species of small fish like clownfish or damselfish. These creatures generally do not pose a threat to humans and are essential parts of the marine ecosystem.

What are all the sea creatures?

Well you can name all the sea creatures discovered but it would take months! And it is not possible to name ALL of the sea creatures living today, most of the earth is covered in water, and we haven't even discovered half of it!

What is the largest land mammal to have ever lived?

Indricotherium is an extinct early relative of modern rhinos that lived during the late Oligocene and early Miocene Epochs of the Cenozoic Era. It was also the largest land mammal ever to live on land, at about 25 feet

long, 17 feet tall, and weighing nearly 18 tons. In terms of weight, it was four times larger than a modern day bull elephant and rivaled the size of large sauropod dinosaurs that lived during the Mesozoic. Fossils of indricotherium have been unearthed in the Baluchistan province of Pakistan.

Do dolphins hunt in pods?

Bottlenose dolphins appear to sometimes work in groups to herd and catch fish and other prey. They organise themselves in wide groups, rather than concentrated groups. Herding may involve the group circling the smaller fish whilst one dolphin at a time takes its turn to go in and feed, or it may involve herding them up onto a sandbank or reef. Sometimes, a couple of the dolphins in the group, or pod, will dive beneath a school of fish, virtually pushing them upward to the rest of the dolphins waiting to feed. They have even been observed hitting the fish with their tails to temporarily stun them.

Bottlenose dolphins will not eat all the resources in one area, but always leave some and move on to new feeding grounds.
Bottlenose dolphins eat many kinds of fish, squid, shrimp and small rays and sharks. ~Quoted from the answer to a similar question: "How does a bottlenose dolphin get its food?"

What purpose do whales serve?

Whales play a critical role in the marine ecosystem as they help regulate the populations of their prey, such as krill, fish, and squid. Their massive bodies also store large amounts of carbon, which helps mitigate climate change. In addition, whales are important for tourism and inspire awe and wonder in people around the world.

Does a male dolphin take care of his calf?

Male dolphins typically do not take a direct role in calf care. It is the female dolphins, including other female members of the pod, that are primarily responsible for raising and caring for the calves, while males may provide protection to the group as a whole.

What kind of animal is an aquatic herbivore?

An aquatic herbivore is an animal that lives primarily in water and feeds on plants or algae. Examples include manatees, sea turtles, and some species of fish like the parrotfish.

Is it possible for a whale to drown?

Yes, whales can drown. Despite being marine mammals, they still need to breathe air, so if they are unable to reach the surface to breathe, they can drown. This can happen if a whale is entangled in fishing gear or stranded on land.

What is the deepest diving marine mammal?

The deepest diving marine mammal is the Cuvier's beaked whale, which has been recorded diving to depths of over 9,800 feet (3,000 meters). This species is known for their remarkable ability to dive to extreme depths in search of their primary prey, deep-water squid.

How does a sea lion balance a ball?

Sea lions have special whisker-like structures on their faces called vibrissae. The vibrissae are filled with nerves so that the sea lion can feel with them, and surrounded by muscles so that the sea lion can move them. The sea lion can use them to balance and hold a ball, much like a human balancing something on his/her fingertips.

What is the name for baby whales?

Baby whales are called calves. Just like baby cows, but way bigger and way cooler. So next time you see a cute little whale, you can say "aww, look at that adorable calf!"

What kind of sea creatures are omnivores?

The word 'omnivores' just means a creature that eats just about anything; i.e humans are omnivores unless you are vegetarian or similar.

How do sea lions move?

Sea lions move by using their powerful front flippers to "walk" or crawl on land and by using a combination of their front and hind flippers to swim in the water. They are very agile and versatile swimmers, able to reach high speeds and perform quick maneuvers to catch prey or evade predators. On land, they are also quite agile and can move surprisingly fast despite their large size.

How many seals are killed in Canada?

In the past five years alone, more than one million seals have been slaughtered in the commercial seal hunt in Canada. The actual number of seals killed is likely higher than that, though, because many seals are shot at and injured in the course of the hunt, and many of these animals slip into the water, where they die slowly and are not counted or recovered.

What is a whales average lifespan?

The average lifespan varies by each different species of whale. For example, a bowhead whale can live to 130 years old.Compare to gray whales who can only live 1/3 of that.


What is the life expectancy of a minke whale?

This depends because many die before their expected life span. Typically, the live until they are between 40 and 50 years old. However, many die earlier because of either orcas or humans killing them.

What the name of a scientist who studies sea creatures?

Marine biologist.

Actually, a Marine Biologist is someone who studies marine organisms (plants, oceans, and animals), but someone who studies MAINLY marine mammals is a marine mammalogist.

What groups are dolphins in?

Dolphins are in the group of marine mammals called cetaceans, specifically within the family Delphinidae. Within this family, there are different genera and species of dolphins, such as bottlenose dolphins, killer whales, and spinner dolphins.

Is a whale in the Phylum Chordata?

Yes, whales are chordates. They are also vertebrates, meaning they have a skeletal system.

However, there is more to it than that, especially given that there are two invertebrate chordate groups - Urochordata (tunicates) and Cephalachordata (lancelets) - whose backbone is not in the form of actual vertebrae.

As Chordates (or members of the phylum Chordata), whales share the following characteristics:

  • dorsal nerve cord which is a bundle of nerve fibres which runs down the back. It connects the brain with the lateral muscles and other organs.
  • notochordwhich is a cartilaginous rod running underneath, and supporting, the nerve cord - in the case of the whale, a spine.
  • post-anal tail - an extension of the body past the anal opening. (This feature is not always present in some adult Chordates such as frogs and humans, but it is present in the whale.)
  • Pharyngeal pouches - Chordates, at some stage of their life, have pharyngeal grooves and pouches that develop into other essential parts of their anatomy.

What specie is the whale in?

Whales are a diverse group of marine mammals belonging to the order Cetacea. There are many different species of whales, including the blue whale, humpback whale, sperm whale, and killer whale.

What is a whales binomial name?

The binomial name for a whale is Balaenoptera musculus, which refers to the species of blue whale.

What is a zoological name for a whale?

Balaenoptera

Whale is the common name for marine mammals of the order Cetacea. The suborders are Odontoceti (toothed whales) and Mysticeti (baleen whales).
