Yup, that is right- a man alter sex

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 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 becomes the new female.

Anemone fish try hermaphrodites (meaning a single individual keeps one another female and male reproductive body organs at some stage in existence) consequently they are by no means really the only fish to make use of that it fascinating mating strategy. Hermaphroditism is pretty common in invertebrates (including the sea slug) however, fishes would be the only vertebrates regarded as practical hermaphrodites (in the place of instances of hermaphroditism hence arise due to mutations and individuals aren’t functionally reproductive). In the more than 33,000 species of fishes, hermaphroditism has separately evolved many times in almost any organizations, also it takes on a number of different models.

Multiple Hermaphroditism- In this form of hermaphroditism, a single individual possess functional male AND female gametes (reproductive cells- i.e. Read more
