to help keep buoyancy
SHARKS.

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.
Whale Sharks are the largest Sharks.

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.
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.

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.
