THE REPRODUCTIVE SEASON AND LARVAL DEVELOPMENT OF THE BARNACLETETRACLITA SERRATADARWIN

Abstract
The presence of embryos in the mantle cavity of T. serrata Darwin, and in Octomeris angulosa Sowerby and Balanus maxillaris Gronovius for comparison, was monitored. In all species breeding extended over 5-8 mo., depending on the species. Breeding seasons showed slight variation annually. T. serrata nauplii were cultured on a diet of mussel eggs in the laboratory and the anatomical features of the different nauplius stages are described.
