Palaemon pugio, commonly known as daggerblade grass shrimp, is a small, transparent species of shrimp with yellow coloring and brownish spots.[1] It can be found in estuarine and tidal marsh habitats throughout the western Atlantic Ocean and Gulf of Mexico. Palaemon pugio has a smooth carapace and abdomen, as well as three pairs of legs. The second pair is the strongest, while the third pair lacks chelae (claws). It reaches a length of around 5 cm (2.0 in), and has a life span of around one year. Like most grass shrimp, it is a forager and feeds on a variety of items, including microalgae. They themselves are consumed by killifish and other small foraging fish.[2]
