Concerning message #20018:

Dear Bill and Richard,
In the first picture of the message, it appears that the rhinophores have rotated and the anterior line is now pointing to the left side of the animal (the right side of the photo). Is this my imagination or are rhinophores directional? Obviously this is the first time I've noticed this.

Dear Phil,
Thanks for noticing that. Yes they are able to swivel their rhinophores around like this - a bit like a dog or rabbit moving its ears to get a more precise fix on a sound. I guess when your 'view' of the world is esentially based on a palette of chemicals, any means of getting a better 'view' is valuable.

Best wishes,
Bill Rudman
