Sharks are covered in placoid scales which do not grow in size as the fish does, instead more scales are added. Research has shown that scales create small vortices which serve to reduce drag.
No, they are only found on male sharks."Claspers are rolls of cartilage that become stiffened with calcium in the adult. The presence or absence of these claspers make it very easy to differentiate males from females..."

Geographers use scales to accurately represent the size and distance of features on maps relative to the actual size on Earth's surface. Scales help to maintain proportion and ensure that maps are a true representation of reality. Different scales are used depending on the level of detail needed for a specific map or study.
Oxygen is used in the launch of space vehicles to make discoveries.
Cardiac muscle fibers are arranged in a crisscross pattern, allowing for efficient contraction and relaxation of the heart. This arrangement helps coordinate the pumping action of the heart and ensures effective blood flow throughout the body.
Sharks, as an example, do not have scales. Re: Sharks instead have something like skin, but have these things on them that make them very rough. They could even scrape off your skin!! For a weird fact, people used to use the skin of sharks as sandpaper.
Sharks are fish so, like all fish, they have scales. In the case of sharks, these scales are somewhat different in composition, and actually make up a yep of skin. Shark skin is made up of tiny, hard, tooth-like structures known as dermal denticles or placoid scales.

A swimmer can carry a drowning man without much effort because the human body is naturally buoyant in water. By supporting the person's weight and keeping them afloat, the swimmer can help the drowning individual to safety. Additionally, proper technique and skill in swimming can make the rescue process easier and more efficient.
