Solution
The correct option is C Protopterus
The genus of Protopterus is commonly known as lung fish. They have small eyes. There is a distinct and prominent snout. There are two pairs of fins. They have filamentous fins. There are cycloid scales which is embedded in skin. These are elongated and snake like fishes. Lungfish are periodically exposed to water with low oxygen content or situations in which their aquatic environment dries up. Their adaptation for dealing with these conditions is an outpocketing of the gut, related to the swim bladder of other fishes, that serves as a lung. The lung contains many thin-walled blood vessels, so blood flowing through those vessels can pick up oxygen from air gulped into the lung.
Thus, the correct answer is option C.
