Abstract

The mating behavior of Echinolittorina lineolata (d'Orbigny, 1840) as well as spawning and larval development was observed in the laboratory. The egg capsules, when deposited, are translucent with a peripheral base and a dome-shaped top with four concentric rings and contain a single white egg. The embryos develop inside the capsules immersed in a gelatinous liquid (albumin). Veliger larvae hatched 96 h after capsule laying and survived free for up to 3 days in the aquarium but did not undergo metamorphosis. Echinolittorina lineolata can be considered to have a “mixed” development.
