Palaemon serratus, also called the common prawn, is a species of shrimp found in the Atlantic Ocean from Denmark to Mauritania, and in the Mediterranean Sea and Black Sea. Individuals live for 3–5 years in groups of about 40 in rocky crevices at depths of up to 40 m. Females grow faster than males, and the population is highly seasonal, with a pronounced peak in the autumn. They are preyed upon by a variety of fish, including species of Mullidae, Moronidae, Sparidae and Batrachoididae. P. serratus may be distinguished from other species of shrimp by the rostrum, which curves upwards, is bifurcated at the tip and has 6–7 along its upper edge, and 4–5 teeth on the lower edge. Other speciesmay have a slightly curved rostrum, but then the teeth on its dorsal surface continue into the distal third, which is untoothed in P. serratus. P. serratus is pinkish brown, with reddish patterns, and is typically 100 mm in length, making it the largest of the native shrimps and prawns around the British Isles. P. serratus is one of the few invertebrates to have its hearing studied in detail; it is sensitive to frequencies between 100 Hz and 3kHz, with an acuity similar to that of generalist fish [11]. While the hearing range of a P. serrratus individual changes as it grows, all are capable of hearing tones at 500 Hz
