| The countershading of bat rays, a form of camouflage, protects them from predators above and below. |
|
| The downward-projecting photophores may provide countershading by obliterating the silhouette when it is viewed by a predator from below. |
|
| It is a good example of countershading, as its light-coloured back, seen from below, blends into the water surface and sky. |
|
| We therefore report two experiments designed to test whether countershading enhances protection by diminishing the probability of detection by predators. |
|
| To blend into their environment, some marine mammals have countershading. |
|
| The light-producing organs, or photophores, of many deepwater fishes provide a unique form of countershading. |
|
| This countershading makes them hard to see, both from above and below, when swimming. |
|
| The bacteria providing this ventral bioluminescent countershading, as it is called, glow with the colors of moonlight and starlight. |
|
| This link between environment and colouration is called countershading. |
|
| The colouring seen while the animal is hanging may be a kind of countershading for concealment, or it may enhance the bat's simulation of a ripening fruit or a dead leaf. |
|
| Demonstrating countershading, the turtle's underside is lightly colored. |
