Notes on the first record of Tridacna noae (Röding, 1798) (Cardiidae: Tridacninae) in Palawan, Philippines.
The first record of Tridacna noae in the province of Palawan, Philippines was documented on June 21, 2018, at Paraiso Resort, Albaguen Island, Port Barton in the municipality of San Vicente. The single specimen measured 4.5 cm in shell length and was partly buried in a massive coral rock. The mantle edge of the species is lined with teardrop-like patches with white margins. This recent finding is an addition to the seven previously reported giant clam species in Palawan and confirms new sighting location in the existing geographic range. The habitat of the species is a semi-protected cove, about 1 m deep at high tide, with massive coral rocks generally covered with the seaweed Sargassum spp. Potential threats include the shading effects of macro algae and the constant presence of tourists visiting the resort who might accidentally step on the clams. Buoy demarcation to exclude the area from disturbance may help protect the species and other boring giant clam species. Continued assessment may provide information on the status of T. noae in Palawan and in other parts of the country.
