Rostanga bifurcata
- Anatomy


UPPER: The rhinophores are relatively long and the club tapers to a slender stalked knob at the tip. The rhinophore lamellae lie almost horizontally but slope downwards posteriorly.
LOWER: The egg ribbon has only been observed for New South Wales specimens. It consists of large multi-spiralled ribbon of microscopic red eggs. The ribbon is thrown into tight folds along its free end. From personal observations and those of Hunter & Woodward (personal communication) development is planktotrophic, possibly lecithotrophic, small swimming veligers hatching from the egg mass nine days after deposition.
