Cartilaginous fish, such as sharks and rays, do not have a swim bladder like bony fish to help control their buoyancy. Instead, they rely on their large, oily livers to help them stay afloat in the water. By adjusting the amount of oil in their livers, cartilaginous fish can control their buoyancy and stay at their desired depth in the water column. Additionally, their streamlined body shape and powerful swimming abilities also help them navigate and maintain their position in the water without the need for a swim bladder. **

The main difference between cartilaginous fish and bony fish lies in their skeletal structure. Cartilaginous fish, such as sharks and rays, have a skeleton made of cartilage, which is a tough and flexible tissue. On the other hand, bony fish, such as salmon and tuna, have a skeleton made of bone. Additionally, cartilaginous fish have a streamlined body shape and lack a swim bladder, while bony fish have a more diverse body shape and possess a swim bladder to control buoyancy. **

Contemporary plays can be considered modern in the sense that they reflect current societal issues, values, and cultural norms. They often incorporate modern technology, language, and themes that are relevant to today's audience.

Overall, the classification of contemporary plays as modern depends on the context and definition being used. **

A hammerhead shark is a cartilaginous fish, meaning its skeleton is made of cartilage rather than bone. Bony fish, on the other hand, have skeletons made of bone. Mammals, including humans, have a backbone, are warm-blooded, and typically give birth to live young. Additionally, mammals have lungs and breathe air, while fish, including hammerhead sharks, have gills and extract oxygen from water. **
