Green turtle fibropapillomatosis is a disease characterized by
very prominent, externally visible tumors. The tumors may arise
anywhere on the skin, but they are most commonly found at the base
of the flippers. The proliferation of tumors can interfere with
normal swimming and feeding, and growth of tumors on the skin
around the eyes may eventually obscure vision. Occasionally, tumors
associated with this disease are found in internal organs.
