The Comparative Reproductive Physiology of Sea Turtles

摘要: Although the reproductive ecology of marine turtles has been subject numerous long-range studies, physiology these unique animals is little known. Recently, however, preliminary anatomical and endocrinological studies have provided a good basis on which to begin attempt explain several their unusual biological systems. New findings related anatomy Chelonia mydas Lepidochelys olivacea are presented. The female, although having very massive pair simultaneously functioning ovaries, appears in most ways similar other chelonians. Corpora hemorrhagica, corpora lutea atretica from active ovaries briefly described. Ovulation coincides with luteinizing hormone progesterone surge. Sperm probably stored for season after single mating period occur prior first ovulation. Males may also cycle as well nesting seen more or less seasonal. seasonality could be controlled part by melatonin endocrines sea turtle's pineal complex. A hypothetical model reproduction presented hopes stimulating interest physiological approaches study turtle reproduction.
