Palau Nautilus

Nautilus belauensis

Palau Nautilus (Nautilus belauensis) is a species of nautilus that is native to the waters around Palau, an island nation in the western Pacific Ocean. 

These creatures are a type of cephalopod, a group of animals that also includes squids and octopuses. Nautiluses are characterized by their distinctive shells, which are comprised of a series of chambers that are filled with gas to help the animal maintain buoyancy.

In terms of size, Palau Nautiluses typically reach lengths of up to 20 cm (7.9 in), and can have a shell diameter of up to 30 cm (11.8 in).

Palau Nautiluses are found in the shallow waters around Palau, typically at depths ranging from 20 to 100 meters (66 to 328 feet). They prefer habitats with rocky or coral formations, as these provide plenty of hiding places and opportunities for foraging.

Palau Nautiluses feed on a variety of small organisms, including crustaceans, mollusks, and small fish. They use their well-developed tentacles to capture prey and bring it to their beak-like mouths for consumption.

Nautiluses are generally solitary creatures that spend most of their time hiding in crevices or under rocks. They are nocturnal and become active at night, when they venture out to hunt for food. 

Despite their slow movements, they are capable of quick bursts of speed when they need to escape from predators.

Palau Nautilus (Nautilus belauensis) is a species of nautilus that is found only in the waters around Palau. It is part of the Nautilidae family, which includes all species of nautiluses. 

Nautiluses are considered to be a “living fossil” because they have remained largely unchanged for millions of years, and are thought to be one of the most primitive forms of cephalopods.
