Reproduction Preferences Additional Information | The shrimp Hippolyte inermis Leach, 1815 lives in shallow waters of the Mediterranean Sea and along the Atlantic coast of Spain. It forms stable populations in seagrass meadows, mainly in Posidonia oceanica and Cymodocea nodosa. Most individuals exhibit a green mimic colour. Investigations by Reverberi (1950) and Veillet et al. (1963) demonstrated individuals experiencing a male stage prior to switching to female i.e. protandric sex reversal. Juvenile diet shifts from zooplankton (larvae) to microalgae and microzoobenthos (settled postlarvae). Sex differentiation occurs at a size of 5-7 mm (Veillet et al. 1963); sex reversal was observed in individuals of 10-13 mm, corresponding to an age of 7-12 months. Not all individuals exhibit sex reversal. In fact, young females of 5-6 mm length are present in natural populations. They are smaller than any male and are produced by direct differentiation. Two main periods of recruitment, spring and fall, were detected in the life cycle of H. inermis. Individuals born in spring grow quickly and develop as either females or males, while individuals born in fall grow slowly and develop as males, changing sex in the next spring. The spring period of maximum abundance of the smaller females in natural populations corresponds to a massive epiphytic production in the leaf stratum of P. oceanica. The size range within Hippolyte is from 20mm to 42mm. | ||||||||||||||
