What brings the nautilus up from the depths?
A small tube near the animal’s tentacles, known as a siphon, expels water under pressure. This propels the nautilus in the opposite direction at high speeds. The life and habits of the nautilus are still largely a mystery, since it spends most of its time in deep water. This provides the animal with buoyancy.
Is nautilus nocturnal?
They steer mostly by sensing obstacles with their tentacles or lightly bumping into them before changing course. When not swimming, it uses tentacles to pull itself along rocks. This species is nocturnal.
How does a nautilus poop?
A duct called the siphuncle connects the chambers so that, when necessary, the nautilus can flood the chambers with water to make itself sink again. This water enters the mantle cavity and is expelled through a siphon.
What makes nautilus unique?
The chambered nautilus lives in deep waters of the open ocean and is one of very few species of shelled invertebrates that live in the water column instead of in contact with the seafloor or reef surface. This species has as many as 90 appendages, unlike the octopuses and squids, which have eight or ten.
How many hearts does a nautilus have?
The cephalopod nautilus, the mesmerizing spiral-shelled marine animal, only has a single heart that pumps blood, unlike its three-hearted relatives. It probably doesn’t need the two extra hearts because of their relatively smaller size and the creature’s very sedentary lifestyle.
Can you eat a nautilus?
They are edible. They can be fried or grilled and taste a bit fishier conpared to othe cephalopods.
Is nautilus a Bilgewater?
A lonely legend as old as the first piers sunk in Bilgewater, the armored goliath known as Nautilus roams the dark waters off the coast of the Blue Flame Isles. Driven by a forgotten betrayal, he strikes without warning, swinging his enormous anchor to save the wretched, and drag the greedy to their doom.
What lives inside a nautilus shell?
Unlike its color-changing cousins, though, the soft-bodied nautilus lives inside its hard external shell. The shell itself has many closed interior chambers or “compartments.” The animal resides in the shell’s largest chamber, while the other chambers function like the ballast tanks of a submarine.
How many Irish died on the Titanic?

Could the Titanic sinking have been prevented?
LONDON: Nearly a century after the sinking of the Titanic, a new study claims that an officer in charge on the bridge could have prevented the tragedy had he acted timely on a warning seconds before the ship struck an iceberg.
Could anything have saved Titanic?
The ship’s watertight bulkheads could have been extended and fully sealed to reduce the risk of flooding. Titanic was constructed with transverse bulkheads (i.e. walls) to divide the ship into 16 watertight compartments, which could be sealed off with doors operated either manually or remotely from the bridge.
Where are most Titanic victims buried?
Fairview Lawn Cemetery
Could the Titanic have been saved by counter flooding?
Counter flooding would delay the sinking, but it would not have saved the Titanic. Once she sank low enough, the sea could still spill over from one bulkhead into another, so she would still sink. The Carpathia arrived at the scene by 4:00 – just 1 hour and 40 minutes after the Titanic sank.
What if Titanic missed the iceberg?
So the Titanic missed the iceberg in 1912, its maiden voyage a success. The ship would not carry the title of world’s largest ship for more than a year, and would soon lose any noteworthiness that came with that title.
