| Outline of Final Research Achievements |
Anemone fishes are sex changing fish, living in tropical sea waters of the Indo-Pacific, forming a social unit consisting of a monogamous pair and several nonbreeders. We studied the relationship between social rank maintenance and sex differentiation using false clown anemone fish. Oral administration of steroid hormones to sexually immature individuals revealed that cortisol did not involve in gonadal sex differentiation, which is induced by gonadal aromatase gene. Dominant behaviors were induced by estradiol, not by androgen. The mechanisms of sex differentiation and behavior expression may be different from other teleost, because the dominant individual in a group must be a female in anemone fishes.
