Spotted Dorid

Fascinating facts about the Spotted Dorid

• Triopha maculata can, on rare occasions, grow as large as 180 mm, a little more than 7 inches, though such individuals are rarely seen. Most members of the species stop growing once they reach about 50 mm, roughly 2 inches, so the larger forms are striking outliers.
• The spotted triopha inhabits the eastern Pacific Ocean, with its range extending from the cool waters of Vancouver, British Columbia, down the coastline to Baja California in Mexico. In addition to this extensive Pacific stretch, the same species has also been recorded in Japanese seas, linking two distant marine regions. Its presence across such a broad latitudinal span demonstrates a tolerance for varied temperate environments.
• Every individual of Triopha maculata bears raised whitish spots covering its dorsal surface, a feature that never varies regardless of the animal's overall colour. These conspicuous markings give the species its specific epithet, maculata, which translates directly to "spotted". The constant presence of the spots makes them a reliable field identifier for this colourful nudibranch.
• The spotted triopha displays a remarkable palette, ranging from a very pale translucent yellow to deeper shades of yellow, orange, red and even dark brown. Regardless of the hue, the dorsal surface is always dotted with raised whitish spots, a feature that gives the species its name maculata. This consistent spotting makes it easy to recognise even when the overall colour shifts dramatically across individuals.
