What are the adaptations in dog fish?

Dogfish, a type of shark, exhibit several adaptations that enhance their survival in marine environments. They have a streamlined body shape that allows for efficient swimming, and their cartilaginous skeleton reduces weight and increases flexibility. Additionally, dogfish possess acute sensory organs, such as the ampullae of Lorenzini, which help them detect electrical signals from prey, and their ability to regulate buoyancy with a large oil-filled liver allows them to maintain depth without expending energy. These adaptations collectively enhance their hunting efficiency and overall survival in diverse aquatic habitats.
