Britain's Kate and William hold tarantula and python

"They're so cool," said Kate, the Duchess of Cambridge, while handling a tarantula named 'Charlotte', at Ulster University Magee campus in Londonderry.

Prince William held a python and said his children "wouldn't believe" what he was holding.

The royal couple sampled guinness while visiting the student union lunch room.

The Duke and Duchess also visited a simulated ambulance built on campus being used to train student paramedics.
