Egg-Laying Sharks. Of the approximately 400 species of sharks, about 40% lay eggs. This is called oviparity. When the eggs are laid, they are in a protective egg case (which sometimes washes up on the beach and is commonly called a mermaid's purse).
what s the truth i am asking this b c there seems to be posts on here that say y sperm swim faster which is what we all prob have heard for the longest time but there have been some recent posts on here that state newer studies now say y sperm aren t any faster than x and they can both swim just as fast so im just wanting to know which one is true if anyone really knows thanks
Swimming Speed of the Average Shark. The general rule of thumb is that sharks can cruise at about 5 mph (8 kph), the speed of the fastest Olympic swimmer. If you're just a good swimmer, they have you beat. But often they are swimming around at a slower speed of about 1.5 mph (2.4 kph). But sharks can swim much faster when they are attacking, about 12 mph or 20 kph, the speed of a running human on land. You're not going to be able to swim away fast enough, you'd need a boat or jet ski or some other equipment.
