Tolkien has produced another classic.

This time the 'tail' belongs to a primate and the thriller set to wow the public is a tiny Black and Gold Howler monkey.

Mum Tolkien is even more of a miracle than normal monkey mums, as she is practically blind.

The nine-year-old at Port Lympne Wild Animal Park had cataracts from an early age and, although she had them removed, there were no lenses small enough to fit her.

So she is unable to focus, but carries on an otherwise normal life.

Now her as-yet unnamed child - it hasn't been sexed yet - is set to join his brothers Legolas, Gimli and Merry, and dad Clyde, after the birth last month.

Deputy head of primates at Port Lympne, Jamie Robertson, said: "Despite only having partial vision Tolkien lives a full an active life and is a good mother and her large family is testament to this. We are really pleased to welcome this new arrival, who is doing really well."

Black and Gold Howler monkeys are one of the largest South American monkeys and are found across Southern Brazil, Paraguay and Argentina. This leaf eating species has a prehensile tail that is known to have its own finger print.

The Howler monkey gets its name from its resonating cry which can be audible from distances of up to 2km away.
