Pteraeolidia semperi (Bergh, 1870)
140mm

Quite a few large individuals were found in the Tulamben area. I hear work is being done on these and there may turn out to be several species.

Juveniles.

Four more from Baturinggit, Cantik Point and Batuniti in November 2024.

This one was apparently regenerating after losing the rear half of his body.
