There are a ton of interesting facts about marine life out there, but you’ll find some of the most fascinating tidbits in shark facts. Let’s read these!!!!
Sharks have been around a very
long time
Based on fossil scales found in
Australia and the United States, scientists hypothesize sharks first appeared
in the ocean around 455 million years ago.
Most sharks have good eyesight
Most sharks can see well in dark
lighted areas, have fantastic night vision, and can see colors. The back of sharks’
eyeballs have a reflective layer of tissue called a tapetum. This helps sharks
see extremely well with little light.
Sharks have special electroreceptor organs
Sharks have small black spots
near the nose, eyes, and mouth. These spots are the ampullae of Lorenzini –
special electroreceptor organs that allow the shark to sense electromagnetic
fields and temperature shifts in the ocean.
Female sharks have thicker skin
During the mating process, male
sharks bite into the female to assume the proper mating position. Male sharks
also have sharp spurs on their genitalia to lock in place when mating. Due to
this unpleasant experience, females have adapted by growing thicker skin for
protection.
Some sharks have the funniest
names
The tasselled wobbegong: this
species is called the carpet shark because of it’s fringed, coral-looking body.
The names of other species will give you a kick too: goblin, megamouth,
Brazilian guitarfish.
Blue sharks are really blue
The blue shark displays a
brilliant blue color on the upper portion of its body and is normally snowy
white beneath. The mako and porbeagle sharks also exhibit a blue coloration,
but it is not nearly as brilliant as that of a blue shark. In life, most sharks
are brown, olive, or grayish.
