Starfish by Leon Heyns Underwater shot of a starfish. Shows the underside as well. Due to the depth, color is different underwater and the under-side of the starfish appear more green than the original yellow and red on the top-side.
No idea why this thing is called the Yellow Boxfish! But these bright yellow, polka-dotted, boxy balloon-shaped fish are found in tropical and temperate marine waters of the Indo-West Pacific.---maybe because it's yellow and box like?
