Zoologist: Mexican fish grow mustaches to attract mates

In what is the greatest fish news since Nemo was found, a new report shows that a Mexican fish appears to grow a mustache in order to attract potential mates.

A report from the University of Oklahoma shows that the Mexican molly fish, a small lake fish in Mexico (hence the name!) has some unusual courtship behavior. Chief among the findings: The fish fertilizes its females internally rather than the usual external fertilization and, the best part, they grow little mustaches!

The mustache is actually a bit of extra skin growing outwardly around the fish’s top lip. Presumably, it also gives them great powers beyond our wildest dreams.

The researches also studied whether the female mollies found the mustache visually attractive, but the lead researcher believes it may also be used physically to excite the female or rub it, and I quote, “on the female’s genitals before mating.” This little Mexican fish mustache is a triumph and form and function.

The Mexican molly’s stance on siestas and sombreros is still unknown.
