摘要: Spermatozoa stored in oviducal glands of sharks sampled off the North American east coast were revealed by viewing stained tissue sections using light microscopy. Of eleven species surveyed, sperm found nine:Alopias vulpinus, Lamna nasus, Carcharhinus obscurus, plumbeus, Galeocerdo cuvieri, Prionace glauca, Rhizoprionodon terraenovae, Sphyrna lewini andSphyrna tiburo. Three insemination patterns are proposed to account for differences noted these findings: (1) non-storage/immediate such asLamna nasus; (2) short-term storage/delayed as which ovulation is prolonged over weeks or months asRhizoprionodon and (3) long-term storage/repeated insemination, a characteristic nomadic asPrionace glauca andCarcharhinus obscurus can store specialized tubules years.
