London: A colony of rare short-snouted sea horses has been spotted in the Thames river, the UK`s Environment Agency said.
The sea horses, which grows up to six inches long, is more commonly found in the waters of the Mediterranean and Canary Islands.
The sightings in the Thames during a routine fisheries survey at Greenwich suggest there may be permanent populations in Britain and that the sea horses, which mate for life after
elaborate courtship rituals, may be breeding in the Thames, `The Daily Telegraph` reported.
Emma Barton, a fisheries officer at the Environment Agency, said: "The sea horse we found was only a juvenile, suggesting that they may be breeding nearby. This is a really
good sign that sea horse populations are not only increasing but spreading to locations where they haven`t been seen before."
She added: "We hope further improvements to water quality and habitat in the Thames will encourage more of these rare species to take up residence."
