Fin's Fish Guide
The Arrow stargazer (Gillellus greyae) is a saltwater fish of the family Dactyloscopidae that grows up to 9 cm.
Description
Grey's 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 sand patches around coral reefs, seagrass beds, boulders and pilings, where it largely buries itself with only the eyes showing. As an ambush hunter it snaps small invertebrates. Unlike the true stargazers it has no venom or electric organ.
