Late Season Fiddlers
There are large numbers of African fiddler crabs (Uca tangeri) living in the mud of the Ria Formosa. The textbooks say that they hibernate deep in their burrows from October until April. However, if the temperature rises above 20C then up they come. These were actively displaying in Olhao in early November. Their appearances ceased a few days later when it got a little colder.
