The Smooth stargazer (Kathetostoma averruncus) is a saltwater fish of the family Uranoscopidae that grows up to 32 cm.
Description
The smooth stargazer is a bottom fish of the stargazer family (Uranoscopidae) from the eastern Pacific. The species grows to about 32 cm and has a stocky body with a large, upward-directed mouth and eyes on top of the flattened head. It buries itself in the soft bottom and waits there, with only the eyes and mouth visible, for prey; it feeds mainly on other fishes, which it engulfs with a swift lunge. Above each pectoral fin it bears a sharp, venomous shoulder spine that can give a painful puncture wound. In addition, stargazers have an electric organ behind the eyes. Therefore handle a caught specimen with extreme care.
