Chelidonura amoena mating

June 21, 2003
From: Paul Whitehead

Dear Bill,
Whilst in the Puerta Gallera, Philippines in May of this year I happened across what I believe to be two Chelidonura amoena mating (?).

There where large numbers of this slug on coral outcrops at around 15 meters however this photograph was taken at about 8 meters next to a coral outcrop - I watched the two approach each other on the sand and then form this circle which I presume is their mating style (?). I had a look on your site but could not find any pictures of actions too similar for Chelidonura amoena.
Best wishes,
Paul Whitehead

Thanks Paul,
Your photo is a bit like Spencer Huang's and Kelvin Tan's which show this species mating. I am interested in your suggestion of a population explosion, as this fits with Todd Garthwaite's report of large numbers in Taiwan. Perhaps it is common for this species to occur in large numbers in the northern part of its range.
Best wishes
Bill Rudman
