The fatspine spurdog (scientific name: Squalus crassispinus) is a type of dogfish. It belongs to the family called Squalidae. This small shark lives in the ocean off the northern coast of Western Australia.
You can find the fatspine spurdog on the continental shelf, which is the edge of the land that slopes into the deep ocean. It usually lives at depths of about 180 to 200 meters (about 590 to 656 feet) below the surface. The longest male fatspine spurdog ever measured was about 56 centimeters (22 inches) long.
About the Fatspine Spurdog
The fatspine spurdog is a rare and slender shark. It has a broad head and a short snout. On its nose, it has a small, wide barbel, which is a whisker-like part that helps it sense things.
What Does It Look Like?
This dogfish has fins that help it swim. Its pectoral fins, located on its sides, have a slightly curved back edge. It has two dorsal fins on its back. The first dorsal fin is fairly tall. Both dorsal fins have very strong and thick spines.
The fatspine spurdog is light grey on its top side and paler underneath. It does not have any white spots on its body. The tips of its dorsal fins are a bit darker than the rest of the fin.
How Does It Reproduce?
The fatspine spurdog reproduces in a special way called ovoviviparous. This means that the mother carries the eggs inside her body. The babies hatch from the eggs while still inside the mother. Then, they are born alive.
