Nudibranchs are colorful marine gastropod mollusks known for their vibrant patterns and lack of a protective shell. They inhabit ocean floors worldwide, favoring coral reefs and rocky substrates. These fascinating creatures exhibit remarkable defense mechanisms, including the ability to absorb toxins from their prey for protection.

Nudibranchia, commonly known as nudibranchs, are found in oceans worldwide. They are particularly abundant in the Indo-Pacific region, including the waters of Australia, Indonesia, and the Philippines. They are also present in the Atlantic Ocean, especially along the coasts of Europe and the Americas.

Nudibranchs inhabit a variety of marine environments, from shallow tidal pools to deep ocean floors. They are often found on coral reefs, rocky substrates, seagrass beds, and undersea caves. They thrive in both tropical and temperate waters, with some species adapted to cold, polar regions.

Nudibranchs occupy a specialized ecological niche as both predators and prey within the marine ecosystem. They primarily feed on sponges, hydroids, anemones, and other invertebrates. Their vibrant colors and patterns often serve as a warning to potential predators about their toxicity or unpalatability, a defense mechanism known as aposematism.
