About
A sea slug (nudibranch) spotted on a rocky seabed at Mesimvria. A sign of spotlessly clean water, and one of the most photogenic finds for snorkelling in Evros.
What it is
Felimare picta, common name Regal Sea Goddess. A dorid nudibranch, a shell-less gastropod mollusc, family Chromodorididae. Grows up to 13cm. Feeds on sponges of the genus Dysidea.
Dark blue to violet colour with yellow spots and a yellow outline along the mantle. Two dark-blue rhinophores at the front and a feather-like gill tuft at the back. Moves slowly over the rocks.
Where it lives
Rocky seabeds across the Mediterranean, including Greece, Spain, Portugal, the Azores, the Canary Islands and the Gulf of Mexico. Depth 0-55 metres.
Why it matters
Nudibranchs only live in clean, well-oxygenated water. Its presence at Mesimvria confirms what we say about the seabed here: a mixed bottom of sand and rock, crystal-clear water, ideal for snorkelling. It's not toxic like the pufferfish, but it has chemical defences drawn from the sponges it eats.
Seabed & Snorkelling
- Shore: Sand with fine pebble
- Seabed: Flat stones and rocks at 3-5 metres - that's where it lives
- Water: Spotlessly clear, good visibility for a mask
- Snorkelling: Yes, one of the best spots in Evros to find one
Practical Info
Don't touch it. It's extremely sensitive - sunscreen, oils and touch can kill it. Photos only. If you spot one, keep a distance of 30cm.
