This study analysed differences in the timing of egg extrusion, reproductive investment and spatial distribution between primiparous and multiparous females of the southern king crab (SKC) Lithodes santolla. Early publications had reported that, in the San Jorge Gulf (SJG; 45–47°S), Argentina, SKCs mated annually, mainly in December. In this work, in coastal areas of SJG, we found small females in postmoult with recently extruded eggs in September–October. At the same time, one SKC female fraction was in intermoult with eggs close to hatching. Evidence suggests that females with recently extruded eggs were primiparous, while females with eggs close to hatching were multiparous. Primiparous females were less fecund than multiparous females o...
