What is nudi?

Nudis or nudibranchs (scientific name: Nudibranchia) are a group of soft-bodied, sea slugs that are known for their amazing colors and forms. They are found in diverse environments, from shallow reefs to deep-sea hydrothermal vents, and they come in different sizes and shapes, ranging from a few millimeters to over 30 centimeters in length.

Nudis are known for their striking visual appearance, which they have developed as a form of defense mechanism. Many nudis have bright colors, complex patterns, and sometimes even appendages that can mimic other animals or blend in with their surroundings. This helps them avoid predators and makes them difficult to detect.

There are over 3,000 species of nudis known to science, and new species are still being discovered. They are found in almost all parts of the world's oceans, except the polar regions. Nudibranchs are carnivorous and feed on a variety of prey, such as sponges, bryozoans, hydroids, and other invertebrates.

Nudis reproduce sexually, and some species also have a unique form of asexual reproduction called "autotomy," which allows them to break off and regenerate parts of their bodies. Some nudis have a lifespan of only a few months, while others can live up to a year or more.

Nudis have become increasingly popular among divers and underwater photographers, who admire their beauty and strange forms. Nevertheless, many nudis are threatened by water pollution, overfishing, and other human activities that have degraded their habitat.
