Etymology
Yongeichthys: in honnor of Sir Charles Maurice Yonge (1899-1986) who was an English marine zoologist + from Greek, ichthys = fish.
nebulosus: from Latin, nebula = cloud + from Latin suffix, -osus = misty, foggy, clouded, obscure.
Original description: Gobius nebulosus Forsskål, 1775 - Type locality: Jeddah, Saudi Arabia, Red Sea.
Distribution
Red Sea, Indo-West Pacific: East Africa east to Society Islands, south to Western Australia and Queensland (Australia) and New Caledonia.
Biology
Solitary. Found over silty and muddy bottoms around inner reefs. Common in mangroves and enter estuaries and rivers. Toxin concentrated in the skin. Contains 28.7 µg/g tetrodotoxin in the internal organs while the flesh holds 1.7 µg/g. Poisonous to eat.
