Short Report


Litter size and details of the reproductive biology of female brown guitarfish Rhinobatos schlegelii from the Penghu Islands, Taiwan, are provided for the first time. Litter size ranged 1–14 (mean 8.5), with an embryonic sex ratio of 1:1. Vitellogenesis proceeded in parallel with gestation.
