Encyclopedia
Turricula bijubata, common name the crested turrid, is a species
of sea snail
, a marine gastropod mollusk in the family
Clavatulidae
.
The color of the shell is chocolate-brown, encircled by narrow, lighter-colored keels The second keel, which is somewhat stronger than the
others, is often broken up into small tubercles. The interior of the aperture
is chocolate-colored. The siphonal canal
is short. It is distinguished from Turridrupa cincta
(Lamarck, 1822) by its narrower form, a longer spire
, sharper ridges and a darker color.

Siphonal canal
Some sea marine gastropods have a soft tubular anterior extension of the mantle called a siphon through which water is drawn into the mantle cavity and over the gill and which serves as a chemoreceptor to locate food. In many carnivorous snails, where the siphon is particularly long, the structure...
