Countershading

Bathytitan vendari is an example of marine creature that uses countershading.

Countershading is an adaptation strongly correlated with a pelagic lifestyle. 

Description Edit

The ventral side of the body is more lightly colored than the dorsal side, meaning that when viewed from below, they blend in with the light coming from water’s surface, and when viewed from above, they’re camouflaged against the darkness of the deeper layers of the water column. 

This colour pattern benefits both predators and prey, and so is likely to be widespread among many oceanic clades, including among our clade of carangiform swimmers, which along with their speed and streamlined bodies, will help them become the dominant clade of pelagic predators. 

Examples Edit

Pelagic acanthopods, such as Teleopterids and Ptilopods, have a ventral side lighter than their dorsal side. These are examples of countershading.
