Adhesive demersal eggs spawned by two southern Australian porcupine puffers

Abstract

Eggs spawned in the Shimonoseki Marine Science Museum Aquarium by eight species of Diodontidae (Allomycterus pilatus, Chilomycterus antennatus, Ch. reticulatus, Ch. schoepfii, Cyclichthys orbicularis, Diodon hystrix, D. holocanthus and D. nicthemerus), representing four genera, were mostly pelagic, only A. pilatus and D. nicthemerus spawning adhesive demersal eggs. The adaptive implications of such demersal eggs require comparative studies on diodontid spawning ecology.
