Now you see them, now you don't.

These tiny lizards are actually baby chameleons, famed for their ability to change colour according to their surroundings and they have just hatched at a children's farm.

It is the first time Ponderosa Rural Therapeutic Centre, in Heckmondwike, has attempted to incubate chameleon eggs and it has been a resounding success.

Farm manager Maureen Cook said: "We would have been happy with two but we have now hatched 13.

"We incubated them for eight months in a make-shift incubator, which worked very well. This is the first time we have managed to anything like this and they are proving very popular."

The Yemen chameleons are not the only unusual animal at the centre, off Smithies Lane. On show are one hundred exotic and rare breed animals, including new additions of 11 baby snakes and millipedes.

The centre, which is run as a non-profit making voluntary organisation, is open every day between 10am and 4pm. Admission is £2.50 for adults and £2 for children and pensioners.
