CHANGE SEX
OYSTER ROMANCE SYDNEY, March 17. This is love-making time in oysterland. Millions of the shellfish are how spawning. "An oyster may be crossed in love,' wrote It. B. Sheridan, but Mr. T. C. Rou'glilcy, economic zoologist to Ihe Technological Museum, who has made a study of our oysters and their habits', doubts it. Each female lays several millions of eggs, for whore there is enormous wastage, Nature is very prolific. A fertilised egg within six hours has a number of hairs with which it propels itself through the water and within 34 hours it i.s completely enveloped in a shell. Oysters change their sex. Practically every oyster is born a male, yet 85 per cent of those that reach marketable si/.e 'are females, said Mr. Roughloy.
