The oceans harbor a wide array of reproductive tactics, and some of them are pretty darn weird. This week we have already learned about parasitic males and some slightly unromantic mating strategies. We also learned that the movie “Finding Nemo” would be far different if screen writers accurately depicted the symbiotic relationship between Nemo, nemonemomne” home. But that isn’t the only thing Pixar got wrong. Anemone fish (also called “clown fish”) start their life off as males (like Nemo and Marlin) and live in a ceny fatflirt single anemone with several other males and a single, larger female (Figure 1). The movie is doing okay so far, but here’s the hitch- when that large female dies (o, like Nemo’s mom did!) the breeding group does not simply usher a new female into their ranks. The largest of the males actually will get the new female.

Anemone fish is actually hermaphrodites (meaning a single person provides each other men and women reproductive body organs at some stage in existence) and therefore are never the only real seafood to use so it interesting mating strategy.Read More
