Nautilus
 The
Nautilus of Osprey Reef, Nautilus pompilius spend their
whole life cycle there, as they are "imprisoned' by
the 1500 metre deep surrounding waters and their lack of
a larval dispersal phase. For this reason, Osprey Reef is
the ideal location for a research project into these amazing
deep sea creatures.
During
each expedition our researchers conduct deep water trapping
at a variety of sites and depths to seek new deep sea animals
and to search for the undiscovered juvenile nautilus habitat.
With the expertise of the nautilus biologists the average
capture rate of 14 nautilus per trapping sessions is consistent!
Tagging
and releasing the animals at night after a day of relaxation
in cooled tanks onboard Undersea Explorer ensures their
wellbeing. High recapture rates of animals up to 2 ½
years later shows the success of this method. Recapture
data estimates a population of approximately 7,500 in the
immediate area, and is producing excellent growth rate information.
This is the most comprehensive live nautilus study ever
conducted. As guest on board you can help identify these
creatures and even sponsor the programme by naming them.
