"The stargazers are a family Uranoscopidae of perciform fish that have eyes on top of their heads (hence the name). The family includes about 51 species (one extinct) in 8 genera, all marine and found worldwide in shallow waters.
In addition to the top-mounted eyes, stargazers also have a large upward-facing mouth in a large head. Their usual habit is to bury themselves in sand, and leap upwards to ambush prey (benthic fish and invertebrates) that pass overhead. Some species have a worm-shaped lure growing out of the floor of the mouth, which they can wiggle to attract prey's attention. Both the dorsal and anal fins are relatively long; some lack dorsal spines. Lengths range from 18 cm up to 90 cm, for the giant stargazer Kathetostoma giganteum.
Stargazers are venomous; they have two large poison spines situated behind the opercle and above the pectoral fins. Some species can also cause electric shocks. They have an electric organ consisting of modified eye muscles. They are one of the few marine bony fishes that are electrogenic. They are also unique among electric fish in not possessing specialized electroreceptors."
