Abstract

Nudibranches are the largest group of Hetrerobranches, (a sub-branch of Opisthobranchia)
and are widespread and cosmopolitan species. They vary in shape and colors and occur in all
waters from intertidal to deep sea zones and from polar to the tropics regions. Nudibranches
are subdivided in two main groups including Anthobranchia and Cladobranchia. In the present
study, based on morphology the svudied species was identified as Goniobranchus annulatus
that belong to Anthrobranchia group. In molecular analysis the sequences of the partial
mitochondrial COI gene of Goniobranchus annulatus species from Iran with 15 similar
sequence of nudibrnaches from genbank were compared. Phylogenetic based on
Neighbor_joining analyze showed a monophyly relationships between families of
nudibranches and also revealed that Goniobranchus vibratus is a sister taxa to the
Gonidbranchus annulatus from Iran Goniobranchus annulatus with 100% bootstrap support.
