چکیده
The Eastern Mediterranean basin is facing a high invasion rate of mainly Indo-Pacific species entering through the Suez Canal. The needlespined urchin, Diadema setosum, was first documented in the Mediterranean in 2006 off southern Turkey. The new record of D. setosum in September 2009 represents the first evidence of its presence in Lebanese coastal waters.

DNA barcoding and morphological analyses revealed validity of Diadema clarki Ikeda, 1939 (Echinodermata, Echinoidea, Diadematidae)
A long-spined sea urchin Diadema-sp reported from Japanese waters was genetically distinct from all known Diadema species, but it remained undescribed. Extensive field surveys in Japan with molecular identification performed in the present study determined five phenotypes (I to V) in Diadema-sp according to the presence and/or shape of a white streak and blue iridophore lines in the naked space...
