Abstract
Previous behavioral observations of Loligo pealeii revealed the potential f or multiple paternity within individual egg capsules, each containing 100 t o 300 eggs. Five egg capsules, sampled from 3 nearshore locations over 2 yr , were tested for multiple paternity using 3 microsatellite loci. The minim um number of potential fathers was derived from the number of different all eles present in the progeny. All 5 egg capsules exhibited multiple paternit y: genetic markers of at least 4 fathers were found in 2 egg capsules; at l east 3 fathers were found in 1 egg capsule, and at least 2 fathers were fou nd in the remaining 2 egg capsules.
