Restricted movement in anemonefish causes protandry so the species has better chances of surviving

I wish you good luck as well. :) I am sorry that I was not available to write my debate argument sooner; I hope you understand. (I sent you a message explaining). Clown fish do not travel very from their homes. For the most part, a clown fish does remain within a 6-12 inch radius of it's home during their entire lifetimes. Assuming we all remember the fictitious movie, Finding Nemo, there were actually several things that were true. In the beginning of the movie, when Coral (Nemo's mother) and Marlin see the shark, Marlin suggests that they go back to the anemone. Clown fish are not predators. They are small fish and sometimes (but not always) born with disease(s) or naturally born with oddly sized pectoral fins that cause difficulties with swimming. Since they are not predators and cannot swim fast (as well as not having a poison or toxin to protect itself with) makes them extremely vulnerable. They become limited to a select space in order to stay safe. The result of being limited for a select number of reasons creates a rather hard to find a mate. Believe it or not, but all clownfish are born as males. There is no clownfish that is born with a female reproductive organ; only the ability the change their gender. If all of them are born as males and they live in a limited space of generally 6-12 inches of their home, it creates a little problem for the survival of the species. They do not always live in massive schools like other fish; they vary in many sizes. A clownfish hierarchy is not the same as patriarchy. A school comes to together and in the beginning, consisting of only males, the largest clownfish will change and turn into a female as the second largest will be the King as female will be the Queen holding the most authority-- when the female dies, the cycle will start all over again and the largest male takes her spot and the next male will take the "King" position". A notable university called, Yale, had a research study done on the topic of 'Why don't more animals practice sequential hermaphroditism? ' Suzanne Alonzo, a tenured professor of ecology and evolutionary biology at Yale University, said "Here, we investigate whether costs of changing sex can favor dioecy. Our analyses suggest that dioecy is favored only when costs of changing sex are large. Moreover, the fitness effect of costs and the strength of male size advantage are not static but change with the population composition, resulting in a dynamic evolutionary game between sex change and dioecy. ". .. "We were surprised to see that a hermaphrodite could spend 30 percent of its lifetime in the process of change sex, and still persist in a population," said Kazancıoğlu, a graduate Yale student that worked on the protect with Alonzo. Sequential hermaphroditism is a trait found in this species as a survival tactic due to the limited mobility and all-male-born species where the population only survives due to this naturally selected evolutionary practice. Defintions: Dioecy: "Having the male and female reproductive organs borne on separate individuals of the same species. Characterized by species in which the male and female reproductive organs occur on different individuals; sexually distinct. " Heirarchy: "a system of persons or things arranged in a graded order" 1. ) . http://www.abc.net.au...2.) . http://www.visitsealife.com...3.) . http://www.animalfacts.lv2lvu.com...4.) . http://curiosity.discovery.com...5.) . http://www.sciencedaily.com...6.) . http://www.ncbi.nlm.nih.gov...
