Resumo(s)
Five days after implantation with 11-ketotestosterone (KT) female Lythrypnus dalli exhibited
elevated urinary KT levels and male-like genital papilla morphology. Papilla length increased,
width decreased, and length : width ratio increased. Control fish exhibited increases in papilla
length, and length : width ratio on day 3, but not on day 5. Changes in the total area of the
papilla were not statistically significant. It is suggested that KT mediates genital papilla
morphology rapidly and thus may be a useful indicator of circulating KT in L. dalli.
