BIO 123 Lecture Notes - Lecture 8: Marine Iguana, Mantis, Ejaculation
Document Summary
Bats engage in oral sex (upside down) (licking increases the chance she gets pregnant and produces offspring. Bears raised in captivity adapt and look like they are having oral sex. Males have weapons to fight each other over fighting with female. Courters: find females in water fertilize lots of eggs. Satellites: swim onto beach alone, crowd around mating pairs, fertilize few eggs. The bad ones come back to shore and sneak around (don"t have as much reproductive success) Marine iguanas (females mate only once per season with one male) Sneaky males right behind, trying to copulate and another comes in and tries to as well. Takes male marine iguana at least 3 minutes to ejaculate. Small males often torn away from female before finishing. Functional masturbation: ejaculate into small pouches near their penis and they store it for attractive female, and find her and mates with her later, ejaculation separate from sex.
