Blood cockle or Anadara granosa (also known as Tegillarca granosa) is a species of ark known as the blood cockle or blood due to the red haemoglobin liquid inside. It is found throughout the Indo-Pacific region from the eastern coast of South Africa northwards and eastwards to Southeast Asia, Australia, Polynesia, and up to northern Japan. It lives mainly in the intertidal zone at one to two metres water depth, burrowed down into sand or mud. Adult size is about 5 to 6 cm long and 4 to 5 cm wide. A cockle is a small, edible, saltwater clam, a mollusc in the family Cardiidae. Various species of cockles live in sandy, sheltered beaches throughout the world. The distinctive rounded shells of cockles are bilaterally symmetrical, and are heart-shaped when viewed from the end. Numerous radial evenly-spaced ribs occur in most but not all genera.
