    • ‘In oviparous animals this can include prefertilization decisions such as the production of larger eggs and the deposition of hormones, such as the steroid testosterone, into yolks.’
    • ‘The regulation of hatching behavior in oviparous animals is important for successful reproduction, but is poorly understood.’
    • ‘Females are oviparous and broadcast spawn eggs in the water column as the male does sperm.’
