Sea cucumbers are always one of my favorite animals to see on a dive, if only because I’m always interested to see what they will look like this time! Internally, they are pretty much all the same, but their exteriors can be completely see through or a variety of colors, flattened, or spikey, like this one. I am not exactly sure what determines their shape, but there has to be some benefit for each morphology.
