Description

The warteye stargazer is a sand stargazer (Dactyloscopidae) from the western Atlantic Ocean. The species is small and has eyes set high on the head and an upward-pointing mouth, an adaptation to lie in wait while buried. It lives on sandy bottoms around rocks and small reefs, where it largely buries itself with only the eyes showing. As an ambush hunter it snaps passing small invertebrates and fish larvae. Unlike the true stargazers it has no venom or electric organ.
