Platydoris

Platydoris is a genus of sea slugs, specifically nudibranchs, belonging to the family Discodorididae. These colorful and fascinating creatures are found in the Indo-Pacific region and are known for their distinct flattened body shape and striking coloration patterns. They are carnivorous and primarily feed on sponges.

Common Names

Platydoris species are commonly referred to as "flat dorids" or "flattened dorids" due to their flattened body form. Some species have specific common names, such as the "painted dorid" (Platydoris argo) and the "orange-spotted dorid" (Platydoris ocellata).

Characteristics

Platydoris nudibranchs are characterized by their:

  • Flattened body: They have a broad, flattened body that is wider than it is high.
  • Bright coloration: They exhibit a variety of vibrant colors, often featuring spots, stripes, or intricate patterns.
  • Rhinophores: They possess two club-shaped sensory organs called rhinophores on their head, which are used to detect food and other stimuli.
  • Cerata: They lack cerata, the finger-like projections found in some other nudibranchs.
  • Gill opening: They have a prominent gill opening on the dorsal (upper) surface of their body, which houses the gills used for respiration.
  • Size: Platydoris species can vary in size, with some reaching lengths of up to 10 cm (4 inches).

Environments

Platydoris nudibranchs are found in shallow water habitats in the Indo-Pacific region, typically on coral reefs, rocky shores, and seagrass beds. They are often encountered among their preferred prey, sponges. These sea slugs prefer tropical and subtropical waters with moderate water temperatures.
