Chambered Nautilus

The Chambered Nautilus is the most well known nautilus, and unlike most cephalopods, its ~90 tentacles have no ‘suckers’. It’s shell, which exhibits countershading to protect from predators, displays a nearly perfect logarithmic spiral on its interior, and is lined with mother of pearl (nacre). They have a pair of rhinophores which use olfaction and chemotaxis in order to find their food.
To swim, the nautilus draws water into and out of the living chamber with its hyponome (siphon), which uses jet prepulsion. While water is inside the chamber, the siphuncle extracts salt from it and diffuses it into the blood. The animal adjusts its buoyancy by osmotically pumping gas and fluid into or out of the camerae along the siphuncles. This limits them; they cannot operate under the extreme hydrostatic pressures found at depths greater than approximately 800 metres (2,600 ft). In the wild, nautiluses usually inhabit depths of about 300 metres (980 ft), rising to around 100 metres (330 ft) at night to feed, mate and to lay eggs.

SCALY FOOD GASTROPOD

The first scaly-foot gastropod, Crysomallon squamiferum, was found in 2000 at the bases of black smokers at the Kairei hydrothermal vent field, on the Central Indian Ridge. In contrast to the approximately 2 °C/32 °F ambient water temperature at these depths, water emerges from these vents at temperatures ranging from 60 °C/140 °F up to as high as 464 °C/867 °F.

The snail thriving in these extreme conditions continues to attract deep-sea fan especially with its black, iron-fortified shell and operculum. The snail’s foot is armored with iron-mineral scales. It is protected by scale-shaped sclerites composed of the iron sulfides greigite and pyrite. No other animal is known to use iron sulfides in this way.

Last December a team from JAMSTEC (Japan Agency for Marine-Earth Science and Technology) reported the discovery of a similar white scaly-foot gastropod also in the Indian Ocean.

They found white scaly-foot gastropod during an investigation of habitats at newly found hydrothermal vents in November 2010. Several aggregations of white scaly-foot gastropods were found at the sites. However the white scaly-foot gastropod does not assimilate iron sulfide. The physiological details have not yet been revealed so the questions remain: Are they same species? How did they evolved? Why do black scaly-foots need iron scales? Source and Source

I got this sand dollar done by Johnny at Orlando Tattoo Company- him and all the guys there are phenomenal! It is in honor of my Granny who passed away in 2007. She would spend hours after storms walking along the beach picking up shells for my sister and I, which is why it is tattooed on my foot, as a reminder that I am always walking in faith with her <3

In the first expedition to explore and take samples from a deep-sea vent in the south-west Indian Ocean, remotely operated submarines spotted a range of extraordinary creatures living in the superheated water, some of them new to science
