Brown Grass Shrimp

The Brown Grass Shrimp, scientifically known as Leander tenuicornis, is a small shrimp species found predominantly in tropical regions. This shrimp inhabits the seafloor, thriving at depths ranging from 1 to 71 meters (approximately 3 to 233 feet). They are typically about 2.5 centimeters (approximately 1 inch) in length and are characterized by their brown-grayish coloration. Female shrimps are distinctively marked with two abdominal ocelli, which are eye-like spots on their abdomen.

As members of the order Decapoda, these shrimp exhibit a reproductive system that is predominantly gonochoric, meaning individual shrimps are distinctly male or female. Before mating, they often engage in a precopulatory courtship ritual that involves both chemical (olfactory) and physical (tactile) interactions to facilitate communication between potential mates. The process of transferring sperm usually occurs indirectly.

Leander tenuicornis can be found in various parts of the world, including the Indo-Pacific region, the Atlantic Ocean, and the Mediterranean Sea.
