Yeah, it's likely that envronmental pressures made them so similar. The low depth either means pigmentation (skin colour) isn't a factor or that it's better to be transparent because it's less likely for eyes to notice you. the skeleton-like appearance is so they can, perhaps, play dead when a predator is near.
