Known from Japan, and reported on the Forum from the Philippines
Ose Beach, Suruga Bay, Izu Peninsula, Japan. 5 April 2002, length approx 25mm. Photo: Pamun
See separate page for Anatomical Information
Described from 2 preserved specimens, 7mm long, little published information is available, except for the original anatomical description, and a recent photo in Okutani (2000: Marine Mollusks in Japan, p 798). The most distinctive external feature is the development on the rhinophoral sheath of a long slender tentacle, which can extend to at least twice the length of the body. The translucent whitish body has scattered brown spots and some yellow diagonal streaks. Baba reported that it was found feeding on the hydroid Tubularia mesembryanthemum attached to Zostera.
