Seahorses in the Thames!

An unexpected revelation in a waterway so far north, they have been there for at least 18 months.

"The Zoological Society of London discovered the colony in 2006 but decided to keep quiet until legislation could be put in place to protect the seahorses. They live in the river’s estuary, between Essex and Kent... The Thames discovery illustrates the partial success of attempts to reduce pollution in a river once considered one of the dirtiest in Europe.The clean-up has already resulted in the return of salmon, which were extinct in the Thames from 1833 until 1974 but are now breeding in Berkshire."

As the Times article indicates, however, this may represent not just a success in pollution control, but a beneficial effect of global warming.
