Amphibian spermatogenic cycles are best known from mass breeding anurans and urodeles which have annual cycles featuring both active and quiescent periods. Spermatogenesis of caecilian amphibians is less well known, but recent studies have revealed similar annual cycles for tropical Indian species which have aquatic larvae. Here we report our findings for a(More)

Exogenous administration of 0.20, 0.40 and 0.60 microg/g body weight melatonin over a 24 hr cycle caused an inhibition of Na+, K+ ATPase activity in both brain and gills of A. testudineus. However, Ca2+ ATPase activity in the brain was significantly inhibited by the highest dose, and that in the gill at all the doses of melatonin. Evening injection of(More)
Spermiogenesis, known as spermateleosis in lower vertebrates, is the transformation of the round spermatid into a highly specialized spermatozoon with a species-specific structure. Spermateleosis and sperm morphology of two species of caecilians, Ichthyophis tricolor and Uraeotyphlus cf. narayani, from the Western Ghats of Kerala, India, were studied using(More)
