Question

A tubular snout with terminal mouth occurs in
(a)Solea
(b)Hippocampus
(c)Echeneis
(d)Anguilla

Answer 1

It belongs to the class of the bony fishes. Their body is found to be compressed bilaterally without any scales on the body but consists of dermal rings that divide into rings and parallel lines that are large and tough.

Complete answer:
-A tubular snout is a kind of structure as an extended or elongated head with a mouth at its end. As in Hippocampus.
The eyes are also useful for spotting food as they move independently of one another, covering a broader visual field. Their menu mostly consists of plankton, small crustaceans, and anything small enough to fit through its snout and be swallowed whole.
-Hippocampus will remain motionless until a small animal passes within them such as a shrimp. Within a second, the seahorse will flick its head and suck its prey out of the water column through its long tubular snout. The hippocampus has no teeth or stomach, therefore prey that is caught is swallowed whole and passes rapidly through the digestive system.

Additional Information:
-The hippocampus plays a major role in spatial memory, navigation, and in some animals, episodic memory.
-Solea is one of the varieties of a flatfish found in temperate and tropical seas. They are flattened and are less elongated in body structure and are commercially valuable as they are consumed as food.
-Echeneis is a genus of suckerfish, present in brackish areas and around coral reefs. They have been used for fishing.
-Anguilla is a freshwater eel that has a snake-like body. They are cultured in marine and brackish water called Valliculture.

So, the correct answer is,” Hippocampus”.

Note: -Ancient Greek poets described Hippocampus as “a half-horse,half-fish mythical god”.
-Their biogeographic regions are - Indian ocean and the pacific ocean.
-Their aquatic biomes are reefs and coastal
-Until today, seahorse fossils found in Rimini, Italy are dated to 3,000,000 years ago.
