Chromodoris spp.

Sighting evidence at Looc Bay, Romblon

Looc Bay hosts an exceptional diversity of Chromodoris nudibranchs including C. annae, C. magnifica, and C. willani, each species displaying vivid blue, white, and orange patterns that advertise their chemical defenses. These opisthobranch molluscs feed selectively on specific sponge species and are reliable indicators of healthy reef chemistry. The bay's calm conditions and shallow profile make it ideal for the extended bottom times required for thorough nudibranch surveys.
