Natiloissa

Natiloissa, also known as the "Nautilus" or "paper nautilus," is a genus of marine mollusks belonging to the family Nautilidae. These creatures are characterized by their distinctive spiral shell, which is a characteristic of the class Cephalopoda, to which they belong. The shell of a natiloissa is composed of several chambers, with each new chamber being added to the apex of the spiral as the animal grows. This process is known as coiling.

Natiloissa are known for their unique behavior of rolling their shell to move, a behavior that is not seen in other cephalopods. They are also known for their ability to change color and texture to camouflage themselves. This is achieved through a process called chromatophores, which are cells that contain pigments that can be expanded or contracted to change the animal's appearance.

Natiloissa are found in the tropical and temperate waters of the Atlantic, Pacific, and Indian Oceans. They are typically found at depths of up to 2,000 meters, but some species can be found at depths of up to 5,000 meters. They are known to feed on small crustaceans and other small invertebrates.

Natiloissa are of significant interest to scientists due to their unique anatomy and behavior. They are also of interest to collectors and aquarium enthusiasts due to their distinctive appearance. However, their populations are threatened by overfishing and habitat destruction, and they are listed as vulnerable on the IUCN Red List. Conservation efforts are underway to protect these fascinating creatures.
