What animal has oil stored their livers?
SHARKS.
Why do sharks have oil stored in their livers?
sharks used it for dressing leather and as a source of vitamin A
What organ is absent in a shark's body?
Sharks do not have swim bladders, which are organs found in bony fish that help regulate buoyancy. This absence allows sharks to control their depth in the water column by using their large, oil-filled livers.
What sharks are large in size?
Whale Sharks are the largest Sharks.
Are angel sharks large in size?
yes angel sharks are large in size
What is the buoyancy of a dogfish shark?
Dogfish sharks, like other sharks, have a unique buoyancy system primarily due to their large livers, which are filled with oil. This oil is less dense than water, helping to counteract their weight and providing neutral buoyancy. Their cartilaginous structure also contributes to their ability to maintain buoyancy while swimming. Overall, these adaptations allow dogfish sharks to navigate efficiently in their aquatic environment.
Why do sharks weigh so much?
Sharks weigh a lot primarily due to their large size and unique anatomical features, such as their dense, cartilaginous skeletons, which provide strength and buoyancy. Additionally, their bodies are adapted for efficient swimming, with powerful muscles and a high-fat content in their livers that aids in buoyancy control. Their size also allows them to be effective predators, enabling them to hunt larger prey in various marine environments. Furthermore, many species of sharks can grow quite large, contributing to their overall weight.
Why do sharks have oil in their livers?
to help the shark stay afloat
Why do long distance runners need large carbohydrate stores in their livers and muscles?
why do long distance runners need large carbohydrate stores
Why do the livers of seals contain a large amount of vitamin A?
Liver contains high levels of vitamin A, and because polar bears subsist largely on seals, including seal liver, their own livers are loaded with vitamin A.
Why animals liver are bigger than human liver?
Not all animals livers are bigger (compared to body weight) than humans. However, some animals' livers are a larger proportion of the body weight because those animals are carnivores (unlike humans which are omnivores). A possible reason for this is that carnivores must be prepared for large, infrequent meals - so their liver needs to be large to deal with a sudden large intake of fat. Other animals, such as horses and cows, have larger livers simply because they are a much larger animal than a human (and in fact their livers are smaller relative to body weight).
Why the shark liver is so large and oily?
Oil is stored in shark's livers because livers store oil (or fat). When vertebrates digest food, the food does not go from their intestine to the blood stream but to the liver which decides what to do with it. That includes you. The liver sends some food directly to the blood stream. It gives some additional processing, and rather that release all the food that came through the digestive track at one time it stores some. (Besides that it serves other functions.) If your body suddenly needs more fat than usual, your liver will release it. If the need continues for any length of time, your body will instruct your fat cells to start releasing fat. Sharks work the same way.
