How does the coloration of the viper dogfish assist in survival?

Answer

It allows it to blend into the abyssal background

The viper dogfish typically displays a dark, brownish-black to dark gray coloration. This dark pigmentation acts as a form of natural camouflage in its habitat. By matching the darkness of the deep ocean environment, the shark can effectively hide from potential predators or approach prey undetected, making it a well-adapted predator in the perpetual twilight of the deep sea.
