[NHCOLL-L:2106] Re: scorpions and UV light

[Bente Loudon]

Dear Judy,

This summer I read the most marvellous popular science book: "In the Blink 
of an Eye" by Andrew Parker, published by Simon & Schuster UK Ltd, ISBN 
0-7432-3988 1 PB or HB 0-7432-1980-5.

The whole book is about light and invertebrate vision or light perception 
and the evolution of the eye. This event is proposed to be the cause of the 
Cambrian explosion of phyla. On page 197 scorpion light receptors are 
described.

Regards        Bente T. Loudon
