Platydoris formosa trailing

Hello Bill,

Here we see trailing behaviour of Platydoris formosa from two different night dives on two different locations around Anilao. Is this common for this species as it is for Risbecia tryoni?

Locality: Anilao, Batangas, 8 metres, Philippines, western pacific, 15 and 17 November 2005, Sand and coral patches. Photographer: Reindert Grooters.

Dear Reindert & Mieke,
I can't recall a report of trailing in species of Platydoris before, but it seems quite a widespread behaviour. Perhaps its just more noticeable in relatively active species like chromodorids and some sea hares.

I have included a close-up alongside to show the colour pattern of this species and also the spectacular red rhinophores.

Best wishes,
Bill Rudman
