Profundiconus is the name of a genus of snails from the family of cone snails , whose approximately 27 extant species in the deep sea of the Indo-Pacific life - except for an East Pacific deep-water species.
features
The cone snails of the genus Profundiconus have a very small to very large, usually thin, conical to narrowly conical shell . The shoulder, which is angled at first, is rounded in the later walks, but they can carry a rib. There are few ribs on the early walkways, but they become numerous and smaller on the later walkways. Existing nodes become obsolete early on. The anal notch is flat, the protoconch has few to many threads. The periostracum is smooth, the operculum large and serrated.
The radula teeth , connected to a venom gland , have a barb and a pointed blade that occupies up to half of the front part of the tooth. The teeth lack any serration. The opening at the tip is large, and an outer spike begins next to it, which extends towards the center. There is a fold on the shaft, and a spur sits on the sloping base.
distribution and habitat
The cone snails of the genus Profundiconus are common in the deep sea of the Indo-Pacific , a single species - Profundiconus emersoni - in the deep sea of the Eastern Pacific Ocean .
nutrition
The feeding behavior and prey of deep-sea cone snails are still unknown. Due to the shape of fangs at the radula compared to other cone snails or Pfeilzünglern in which these teeth serve the sticking and poisoning of the prey, it is believed that the snails of the genus Profundiconus polychaete (Polychaeta) eat. The only stomach contents known so far, however, are the beak of a small cephalopod that was eaten by a Profundiconus smirnoides (in Marshall's Profundiconus smirna ) in the deep sea near New Zealand .
