Question

What is the zoological name of dog fish?
A. Torpedo
B. Dasyalis
C. Scoliondon
D. Labeo

Answer 1

Hint: Dog fish is included in the Elasmobranchii class and includes various types of cartilaginous fish. This genus is represented by about nine species, four of which are very common in the Indian Ocean. The dog fishes have an elongated muzzle, a depressed head, and a compressed body. The teeth are similar in both jaws. The caudal pit and the sub-caudal lobe are convex and distinct.

Complete answer:
Let’s look at some important points before answering the question.
Torpedo (Electric Ray)-A marine fish that lives on the seabed that generates enough electricity to scare away prey, such as small fish. Two pectoral fins are attached to the stem. At the back of the torso are a pair of electrical organs. In fact, an electrical organ is a deformed lateral muscle plate that is stimulated by cranial nerves. Torpedoes can generate electricity. Water is collected in a spiral, and not through the mouth, like many fish.
Scoliodon (Dog Fish)-Scoliodon dumerili is commonly found in the Bay of Bengal. It contains several holes, ampullae on the top and bottom of the head. Temperature fluctuations in the surrounding body of water.
On the back of the head there are 5 oblique openings on each side, called gill slits, which communicate from the inside with the pharynx.
Labeo Rohita (Rohu)-Commonly known as Rohu. The Rohu is located in a clear slow stream. Adults are mainly herbivores in their diet. There are two short strands called dumbbells. The tail is uniform. This fish is used as a popular dish.
So, the correct answer is “Option C”.

Note:
The caudal fin surrounds the tail and exhibits asymmetry (upper narrative lobe of the head and lower right lobe of the lower jaw). This type of tail with two types of blades is called a patchy tail. Many dermal plasmoid scales are found in the skin, forming the outer skeleton of the fish. Males may differ from females. The first has a pair of stiff, elongated braces attached to the pelvic fin, egg shape. Some also consume Scoliodon in food containing fish oil.
