The correct spelling of the plural form of Nautilus is "Nautili." This word is pronounced as /ˈnɔː.tɪ.laɪ/ in IPA phonetic transcription. The final "s" indicates that it is a plural form, while the preceding "i" indicates that it follows the Latin declension pattern for neuter nouns. The word "Nautilus" comes from the Greek word "nautilos," which means "sailor." Nautili are marine animals with spiral shells and tentacles, similar to octopuses and squids.
Nautili (singular: nautilus) refers to a group of marine mollusks belonging to the family Nautilidae, which are commonly identifiable due to their spiral-shaped shells. These unique creatures have a rich evolutionary history and are known to have existed for over 500 million years, which makes them living fossils. Nautili are considered cephalopods, but they differ from their cousins, such as squids and octopuses, in various ways.
The shell of a nautilus is composed of a series of interconnected chambers, with the innermost chamber housing the animal itself. As the nautilus grows, it continuously adds new chambers to its shell, expanding it over time. The outer surface of the shell is typically pearly and smooth, while the inside is partitioned by a series of complex walls known as septa. These septa form a series of internal chambers, which the nautilus uses to control buoyancy by altering the amount of water or gas inside them.
Nautili are generally found in the deep waters of the Indo-Pacific region, residing at depths ranging from a few hundred to over a thousand meters. They are predominantly nocturnal creatures, emerging from their resting places at night to search for food. Their diet primarily consists of small fish, crustaceans, and other marine organisms.
Despite being relatively elusive due to their deep-water habitat, nautili are highly prized by collectors and researchers alike due to their distinctiveness and ancient lineage. They play a crucial role in understanding the evolutionary history of cephalopods and provide insights into the marine ecosystem's dynamics.
A shell-fish having a spiral univalve shell with smooth sides; a popular name for a shellfish having a boat-like shell in which it sails on the surface of the sea.

The word "Nautili" is the plural form of the noun "Nautilus". The etymology of "Nautilus" can be traced back to the Latin word "nautilus", which ultimately comes from the Greek word "nautilos" (ναυτίλος). "Nautilos" is derived from the combination of "naus" (ναῦς), meaning "ship" or "boat", and the suffix "-tilos", which indicates something that is twisted or spiral-shaped. Therefore, "Nautili" refers to more than one nautilus, a type of marine mollusk known for its distinctive spiral-shaped shell.
