Egg size and egg composition in polar shrimps (Caridea; Decapoda)
Egg volume and several aspects of egg nutrient content (dry mass, organic content, carbon and nitrogen content) were measured in eggs from five species of polar caridean shrimp (Crustacea; Decapoda): Chorismus antarcticus, Notocrangon antarcticus and Nematocarcinus lanceopes from the Weddell Sea (An...
