In total, 74 nominal species and 7 possible new species of sea slugs
were recorded at a site off the coast of Wai-an in Penghu (the
Pescadores) in the Taiwan Strait from 20 survey dives (including 17
monthly surveys). The Chromodorididae and Phyllidiidae were the 2
most-speciose families. The mean number of species sighted per
monthly survey was 12. The increase in new species recorded
reached a plateau at the 18th survey. The number of families
recorded per survey ranged 2-9. High nudibranch species diversity
is a site-specific attribute of Wai-an. Except for 1 survey, no
species at this site were considered dominant in terms of the abundance
of individuals. Similarities in species composition for pair-wise
monthly samples were low. No obvious trends in temporal changes
in the number of species or species composition were noted.
Key words: Nudibranch, Biodiversity, Penghu.
