On two separate occasions during fieldwork in
Semporna (eastern Sabah, Malaysia), sea anemones of
the family Edwardsiidae were observed attempting to
feed on the nudibranch species Nembrotha lineolata and
Phyllidia ocellata. These are the first in situ observations
of nudibranch predation by sea anemones. This new
record is compared with known information on sea slug
predators.
