1. Name three reef dwelling fish that start life as a female but change to males. What cause the change? See Snakes are related to what species of land snake?
2. What is the name of the whale model hanging from the ceiling?
Answers:
The majority of reef fish change sex at some point throughout their life. In fact,
reef fish that remain as the same sex for their life span (gonochoristic) are in the
minority.
There are many different patterns for sex-change. Some species will begin life as
males and switch to females (protandry), and others switch from female to male
(protogyny). Further still, some will change sex in both directions, and others will
be both sexes at the same time.
Sex-change therefore becomes quite fascinating from several different perspectives.
From the behavioral standpoint, how does a fully functional female behaviorally
become a male in a matter of hours, followed by a physiological and anatomical
change to functionally become the opposite sex. The endocrine system is most likely
responsible for this changing ability, but the hormones have yet to be identified.
Also yet to be identified are the chromosomes and genetic sequences responsible
for allowing this sexual plasticity.
The whale must be a blue whale.
