is a typical prawn with a cylindrical body composed of a carapace at the front and six abdominal segments. It has a short straight rostrum in front of the eyes with distinctive dorsal and ventral teeth. Palaemon elegans
is translucent with red/brown lines on the carapace and abdomen. Just below the large compound eye on each side is the antennule, which is divided into to three parts. Below the antennule is the antenna, which is divided into two parts; the short flat segment (the scaphocerite) and the long whip-like flagellum. The first two pairs of walking legs bear claws (chela) and have yellow and red banding.Palaemon elegans
is very similar to Palaemon serratus, Palaemon longirostris
and Palaemon adspersus
but can be separated from these species by the number of rostral teeth and the mandibular palp, which is composed of two segments.
