Male molly fish in Mexico wear a moustache that makes them appear more sexy to females.ย Scientists were unsure why male Mexican mollies wear an extravagant moustache-like structure on their top lip.

Now a study has revealed that female fish find the moustache sexually attractive, and it is likely to be a sexually selected trait.ย As well as being visually-attractive, the moustache may be used to rub the female fish’s genitals, exciting them.

Details are published in the journal Behavioral Ecology and Sociobiology.ย As their name suggests, Mexican mollies (Poecilia sphenops) live in Mexico, being a fairly common species that resides in a range of habitats from small rivers to creeks and lakes.

The fish has a complicated mating behaviour, with males fertilising females internally, rather than spreading sperm over externally laid eggs.

Well the lady fish would have to be into it, wouldn’t they? Nobody would wear a silly moustache like that unless they thought it was going to get them laid.

These fish are having funcky fuun!
I’m sure we’ll learn something from these fish,
Now guys will be growing moustaches to excite female’s genitales.
In 2013 every guy in the world will have a moustache, if you don’t, you aren’t considered attractive, or sexually available.

‘Molly Fish’, eh? Well, whilst I agree that some stylish facial hair does make a man more attractive ( ๐Ÿ˜‰ ) I somehow doubt that those moustaches are for attracting females. ๐Ÿ˜€ (Please forgive me.)

P.s. Why is that fish’s name Michael Tobler? :)

Perhaps its moustache serves the purpose of a (soup) strainer. Since it is forever constrained to drink something other fish have made love in.
