Nautiluses are cephalopod mollusks characterized by their shells that are coiled forward in a spiral shape. They are a panchronic species: this current species is similar to extinct species found in fossil form.

Summary

[edit]
Description
Français :

Les nautiles sont des mollusques céphalopodes caractérisés par leur coquille enroulée vers l'avant, en forme de spirale. Il s'agit d'une espèce panchronique : cette espèce actuelle est similaire à des espèces éteintes retrouvées sous formes de fossiles. Le nautile ombiliqué identifié ici est une espèce endémique de Nouvelle Calédonie.

Ces photographies ont été réalisées grâce au submersible Cyana.

La campagne CALSUB avait pour objectif l'exploration et l'échantillonnage de la faune des fonds durs ou mixtes des pentes récifales à l'aide d'un submersible, l'étude de la microdistribution de la macrofaune, de la répartition bathymétrique des principales espèces ainsi que des relations faune-sédiment. Cette campagne multidisciplinaire s'est tenue en Nouvelle Calédonie en 1989.

English:

Nautiluses are cephalopod mollusks characterized by their shells that are coiled forward in a spiral shape. They are a panchronic species: this current species is similar to extinct species found in fossil form. The umbilicated nautilus identified here is a species endemic to New Caledonia.

These photographs were taken using the Cyana submersible.

The CALSUB campaign aimed to explore and sample the fauna of hard or mixed bottoms of reef slopes using a submersible, to study the microdistribution of macrofauna, the bathymetric distribution of the main species and the fauna-sediment relationships. This multidisciplinary campaign was held in New Caledonia in 1989.
