People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group, and getting eaten as a result. That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists.
The research team has discovered that subordinate (隶属的)fish voluntarily diet to avoid challenging their larger competitors. “In studying gobies we noticed that only the largest two individuals, a male and female, had breeding(繁殖) rights within the group, ”explains Marian Wong. “All other group members are non-breeding females, each being 5–10% smaller than its next largest competitor. We wanted to find out how they keep this size separation.”
The reason for the size difference was easy to see. Once a subordinate fish grows to within 5–10% of the size of its larger competitor, it causes a fight which usually ends in the smaller goby being driven away from the group. More often than not, the evicted fish is then eaten up.
It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish. Whether they did so voluntarily，by limiting how much they ate, was not clear. The research team decided to do an experiment. They tried to fatten up some of the subordinate gobies to see what happened. To their surprise，the gobies simply refused the extra food they were offered，clearly preferring to remain small and avoid fights, over having a feast.
The discovery challenges the traditional scientific view of how boss individuals keep their position in a group. Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves, so keeping their competitors small.
While the habits of gobies may seem a little mysterious, Dr. Wong explains that understanding the relationships between boss and subordinate animals is important to understanding how hierarchical (等级的) societies remain stable.
The research has proved the fact that voluntary dieting is a habit far from exclusive(排他的) to humans. “As yet, we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature,” the researchers comment. “Data on human dieting suggests that, while humans generally diet to improve health or increase attractiveness, rarely does it improve long term health and males regularly prefer females that are fatter than the females’ own ideal.”

Three years ago. I was arranged to work for a few weeks as a dentist in a new dental clinic at Victor Harbor, to the south of Adelaide and an hour further away than my usual workplace. My first day there was rush driving to a new and unfamiliar clinic and getting used to the different rules and clinical environment.
In my worry and anxiety, and feeling a little unfamiliar in the new setting, I removed my three things: my wedding ring, a ring that belonged to my mother and one that was an anniversary gift from my husband. I wrapped them in a tissue(纸巾) and placed them beside my computer.
During my lunch break, I noticed the wrinkled tissue and thought that it didn’t look very neat and dropped it into the rubbish bin. I went about my duties and my day went on well; I met new patients and felt that I had been productive and efficient. Driving home at the end of the day, just moments before I reached my house, I noticed that I was missing my rings. I felt the heart in my body rose, my cheeks burning red. I went inside and tried to calm down. I felt sick to my stomach and I had that sinking feeling in my heart. I spent an hour or so making calls trying to follow the track of my rings. The first people I called was my manager and clinical leader and they gave me a few contact numbers for cleaners. I got in touch with a lady who managed the cleaning services for the clinic and she informed me that the bins had already been collected.
Heartbroken, I knew nothing could be done now. I had lost my wedding ring and one of my most treasured rings my mother’s wedding ring. Had it not been for my carelessness, all this would not have happened. With great sorrow and regret, I just sat there rooted in my chair.
Paragraph 1:
After two hours or so, I received a most amazing phone call. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
