Smooth Sand Eel

Gymnammodytes semisquamatus (Jourdain 1879)

Gymnammodytes semisquamatus (Smooth Sand Eel) is a species of ray-finned fishes in the family sand lances. Individuals can grow to 30 cm. They have sexual reproduction. Reproduction is iteroparous and oviparous.

Definition: Capable of creating a new organism by combining the genetic material of two gametes, which may come from two parent organisms or from a single organism, in the case of self-fertilizing hermaphrodites.

lens eyes
- URI: https://eol.org/schema/terms/lens_eyes
- Definition: Relative to pinhole eyes, lens eyes have greatly improved resolution and image brightness. The lens converges incoming rays of light, thereby reducing the angle over which each photoreceptor receives light, and forming an image focused on the retina. Most lens eyes have "accommodation"; they can focus an image either by physically moving the lens toward or away from the retina or by using eye muscles to adjust the shape of the lens.
