Can you perceive in your mind’s eye a shark as big as your table knife with teeth as jagged as your table knife? Well, if you can, this is the name of it: the Spined Pygmy Shark. The Spined Pygmy Shark likes to devour squid, shrimp, and mid-water fish like lantern fish. It gets those foods by interrupting in a school of fish and swallowing them whole. It gets its water from its habitat. It gets air by using the air that runs through the water. It lives in a warm climate. It gets the shelter it needs by staying in deep depths. It lives in deep waters down to 6,550 feet deep. On the other hand, it hunts in mid-waters. It is related to the Dogfish Shark. The Spined Pygmy is rarely seen by divers because it lives so deep. It is harmless to humans. Spined Pygmy Sharks are just seven to eight inches long. The shade of the Spined Pygmy Shark is dark gray to black with ashen tipped fins. It has a bulbous snout. The Pygmy Shark’s belly radiances in the dark. This may serve as camouflage for it to avoid being eaten by its enemies. It eliminates shadows when it is seen from beneath it.

The smooth teeth are located in rows that rotate into use as needed. The first two rows are used in obtaining prey; the other rows rotate into place when they are needed to cut the sharks prey. As teeth are lost, broken or worn down, new teeth rotate into their innovative places. There is an extra, round of gills in the wake of each eye. This is also known as a spiracle. It is for the most part most negligible shark in the world. The Spined Pygmy Shark is not on the endangered species list because it lives so deep. Not many other species can eat it there.

I chose this animal to write about because when I first started researching it, I knew I would learn a lot of new stuff because they used the word “luminescent” at the beginning. The thing that interests me about the “Seven-inch Spined Pygmy Shark” is that the website in the bibliography below told me that this shark has a glow-in-the-dark stomach. I also read that it is one of the smallest sharks in the world. Now you have to admit, that is pretty cool.
