Length at first maturity / Size / Weight / Age
Maturity: Lm 14.7, range 2 - 2.4 cm Max length : 20.0 cm TL male/unsexed; (Ref. 363)
Stomatopod of average size; Maximum: 20 cm; common of 12 to 18 cm. Body: with very marked peaks, peaks sub median of the 5th abdominal segment with posterior spines; process lateral of the 5th thoracic segment ending in only one tooth very pointed and bent forwards. Dorsal face of the telson: with a median peak marked well and many small depressions, but deprived of lines of tubers. Dactyl of the leg: kidnapper armed with 6 spines, its regularly convex external edge. Coloring: yellowish or brownish; often reddish or bluish peaks. A dark line extends along the posterior edge from the thoracic segments, 6 to 8 and the abdominal segments, 1 to 5; a median rectangular spot sinks on the second abdominal segment; telson marked of yellow and with 2 spots dark chestnut surrounded of a white ring (Ref. 363).
Importance: Semi-industrial, artisanal and sporting fishing with basic trawls, trémails, bow nets, dredgers and seines of beach. Maximum depth from Ref. 106945.
Males produce sperm ducts rather than spermatophores; females can brood a maximum of 50,000 eggs (Ref. 833). Life cycle: Females incubate eggs in burrows (Ref. 108993). Eggs hatch to planktonic zoea which lasts for 3 months (Ref. 833). Mating behavior: Spawning occurs from winter to spring (Ref. 108993). Females spawn once only (Ref. 108996).
