Egg capsule morphology of Parascyllium variolatum (Duméril, 1853) (Chondrichthyes; Parascylliidae), with notes on oviposition rate in captivity
The egg capsule of Parascyllium variolatum is described for the first time, based on 57 eggs laid by three captive fish over a 167 day study period at Melbourne Aquarium. The egg capsule is bulbous, bearing two elongated horns. An indistinct or rudimentary third horn may be present. Aprons present; fibres present; small lateral fringes present. Notes on oviposition rates are also discussed and were shown to vary from 12 to 39 days with one or two eggs being deposited each time.
