Figure 1. Statoliths from larvae and recent recruits of two species of gastropods. (a) Pair of larval Concholepas concholepas statoliths visible through fragments of larval shell. (b) Statolith in recently settled C. concholepas individual. (c) Near-hatch larva of Kelletia kelletii with statolith visible. (d) Statolith from a near-hatch larva of K. kelletii with possible daily increments. In (b) the arrow indicates a potential "hatch" mark measuring 11.40 ± 0.24 microns (mean ± 1 SE, n = 10) in diameter. In (c) the arrow indicates statolith.
