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.
Placoid scales create turbulence in the water and allow sharks to swim with ease through the water.
The cardiac muscle is arranged spirally around the heart to make it more efficient.
scales show the relationship between the distance on the map and the distance on the ground. (it makes the make more realistic and so you can calculate distances)

Oxygen is used in the launch of space vehicles to make discoveries.
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..."
Because it IS concidered a shark.....wouldn't that make the WHALE SHARK the slowest swimmer sharks?
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.
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.

only when its fried
Justin would date a swimmer if you could make him laugh.
No, heart scales can't make a red gyarados
this makes no sense...
its because someone found that if they have a tinkle on it it will make scales! true true..
it will make waves
The engine was cleaner and more efficient.
you lure the sharks toward you, fly to the black hole, and the sharks get sucked in the black hole
