Ternate false fusus
Hemifusus ternatanus*

Family Melongenidae
updated Oct 2016
Where seen? This large snail is rarely seen alive, although the empty shell is sometimes seen, usually occupied by a hermit crab.

Features: 7-12cm. Shell large, thick with a long siphonal canal. More slender than the more commonly seen Spiral melongena (Pugilina cochlidium). Operculum teardrop-shaped and made out of a horn-like material. Body pale with black speckles. The shell of a living snail is covered with a layer of fine hairs (called the periostracum). These hairs trap surrounding sediment so that the snail blends perfectly into the mud. When the snail dies, the hairs drop off revealing a glossy, orange shell. The large empty shell is often taken over by a hermit crab.
