Spotted Dorid

Triopha maculata

Also known as Spotted Triopha, Speckled Triopha, Maculated Triopha

Spotted dorids glide across kelp holdfasts and rocky reefs along the eastern Pacific coast, displaying vibrant body colors ranging from translucent yellow-white to deep reddish-brown adorned with bright orange or bluish spots. They graze primarily on arborescent bryozoans, using a rasping radula to strip colonial animals from hard substrates. When threatened, they rely on chemical defenses absorbed directly from their prey rather than active flight.
