All the photos whose present in this page, are taken in Etang salé les bains on a Rocky coast
19 December 2006.
17h45 : Approach phase.
The specimen on the right side was 20 cm far from the left one. The
left one seemed to be eating a sponge. Suddenly the right one moved
near the other one.
17h47 : Preliminary phase.
When the right specimen arrived at the head level of its future
partner, it balanced its head from right to left, progressed under the
mantle ( head and the two rhinophores under the mantle seemed to search
the genital aperture....). During this time the other didn't move.
17h48 : Mating phase. Duration? I don't staying around by 15 minutes later when I come back they are
by 50 cm...
