Caption
This channeled tun (Tonna cepa) is about two inches in shell length, with its long siphon (for respiration) and tentacles (with eyes at their base) clearly visible. Tuns are known for their thin shells. They are night predators and are usually seen in sandy areas, feeding on bivalve molluscs (clams, oysters, mussels and scallops) and sea cucumbers.
