The Segmented Body Of A Crab

This little part of a crab has seen better days but there’s still no denying that even just the leg is segmented which means that this counts for a segmented body. (Also with another concerned smiley.)

Adaptation Of Rockweed

This rockweed has adapted to its environment by growing gel filled sacs that are lighter than water, making the seaweed stand closer to the surface enabling it to get more sunlight for photosynthesis. (My smiley looks mildly concerned about the rockweed.)
