Countershading is observed in a wide range of animal groups, both terrestrial, such as deer, and marine, such as sharks. [17] It is the basis of camouflage in both predators and prey. [18] It is used alongside other forms of camouflage including colour matching and disruptive coloration. [18]
Sharks may have a combination of colors on the surface of their body that results in the camouflage technique called countershading. A darker color on the upper side and lighter color on the underside of the body helps prevent visual detection from predators.
It is common in both terrestrial and marine animals. Camouflage can be achieved in many different ways, such as through resemblance to surroundings, disruptive coloration, shadow elimination by countershading or counter-illumination, self-decoration, cryptic behavior, or changeable skin patterns and colour.
A new light system developed by Australian scientists to mimic ocean camouflage may deter Great White Shark attacks, a new study says. Marine predators like sharks locate prey by looking for ...
And now, a new study says sharks have personalities as well. Yes, sharks. Researchers at the Marine Biological Association of the UK and the University of Exeter studied ten small groups of cat sharks

Instead, their thick fur traps air among the individual hairs, keeping the mammals warm and dry. ... by studying the skin of sharks. "There are ten scales per millimetre on the skin surface of a ...
Epaulette sharks are preyed upon by larger fishes such as other sharks. [5] Its coloration provides protective camouflage, [6] while its epaulette is speculated to be an eyespot for distracting or deterring predators. [2] Epaulette sharks are almost all parasitized by the praniza (parasitic) larval stage of gnathiid isopods.
