London, July 1 (IANS) When fish, on the hunt for a mate, have their vision restricted by high levels of pollution or algae, they chose the first mate they find, a new study into deep sea breeding habits has revealed.
Fish can suffer from the aquatic version of beer goggles, a phenomenon in which consumption of alcohol makes physically unattractive people appear beautiful, reports express.co.uk.
Generally what happens is that when waters are clear, the males take time to pick the biggest and best-looking partners who will bear more eggs, says the study by Sweden’s Uppsala University’s ecology and evolution department.
Explaining this, Josefin Sundin, a researcher said: ‘It is just like being in a polluted smokey bar and drinking too much toxic liquid late at night.’
