| Abstract |
The live shells of mytilid mussel, Septifer excisus (Wiegmann, 1837) were collected from the rocks and oyster shells from Jiwani, Balochistan, Pakistan at neap tide from the intertidal zone. The observed specimens were straw to dark purple colour, attached to rocks and oyster shells by its’ byssus threads; closely resemble Brachidontes species but a septum was found, below the beak inside the shell confirming the identification towards the byssally attached mytilid genus Septifer. Septifer excisus has significant difference with other members of the same genus by three characters: septum, beading ribs and posterior adductor scar. This species exists from Triassic to Holocene and has been recorded from many parts of the world. This is the first record from Jiwani, Balochistan, Pakistan. |
