Dear Jeff,

Thanks for these photos. They certainly help to explain its shape. To those of you not familiar with this animal:
Uppermost photo shows two of the cerata on the right side. They look a bit like a many fingered hand with fingers bent as if to catch a ball.
Middle photo: View of one cerata from the middle of the body looking out.
Lower photo: Rhinophore, with small rhinophore club partly hidden in flower-like sheath.

Best wishes,
Bill Rudman
