FEMALE marine snails living off the Perth coast are growing male sex organs on their heads after exposure to the chemical TBT, according to local researchers.
Curtin University researchers have revealed the snails are suffering from imposex, a condition that involves the development of a second sex organ after being exposed to the chemical.
Unlike garden snails, which are hermaphrodites, this species of marine snail has distinct sexes.
She said studies had shown that imposex could stop the females from procreating, potentially reducing the number of snails in the shoreline environment.
