Trapania darvelli, Rudman, 1987

Well, Jeffrey just has a knack for shooting the tiny ones. Here he caught a juvenile Trapania darvelli . Like other developing juvenile slugs the body is still quite short and stout, with what seem like exaggerated rhinophores. Slugs like to grow into their bodies. Once grown it will measure up to about 13 mm, and be far more slender than it is now.

On Jeff’s shot of this little slug person we can clearly see the eye spot and the detail of the perfoliate rhinophores. Wow. The brown tips on all appendages, decorate the white body, and make it easy to ID.

Although I do not see any in Jeff’s photo, this species likely feeds on entoprocts, that are commensal on sponges

This species has been recorded from Vanuatu, Solomon Islands, Malaysia, Hong Kong and now the Philippines.

WEBMASTER'S NOTES : Another great photo by Jeffrey, but then what else might one expect when you put together one of the great slug photographers in the PI with one of the two best slug guides in the PI (Peri and Alexis), the above image is the splendid result!
