BIO202H5 Lecture Notes - Lecture 9: Spermatogenesis, Adrenal Gland, Sea Anemone
Document Summary
Each polyp in a colony broadcast spawns gametes. Gametes from a single colony cannot self-fertilize & must disperse (oily pink slick: happens 5-8 days after full moon during austral spring (tidal currents minimal) Gametogenesis: production of gametes is timed with changes of yophotoreproduction: not released during too windy or too hot weather, this must happen during low tidal currents. Wet season: male with eyespot & band: female prefer male with eyespot that are not too bright (which indicates the male has grown in dry season, seasonal availability has affected how they grow and mate choice. Dry season: cryptic male: male prefer female with eyespot, spermatophore of dry season male provides more resources for female.
