n.南美食用淡水鱼的一种
A large South American freshwater food fish(Arapaima gigas) that typically attains a length of3 meters(10 feet). 巨体舌鱼属一种大型南美淡水食用鱼（巨骨舌鱼）一般长达3米（10英尺）
A diver shares a tank with an adult arapaima fish at an aquarium in Manaus, Brazil. 在巴西的马瑙斯[巴西西北部城市]，一名潜水夫和一头成年巨滑舌鱼同处一池。
The Arapaima uses its bony tongue to crush prey against the roof of its mouth before swallowing. 在咽下去之前，巨骨舌鱼使用其带骨头的舌头将猎物与自己的上颚仿佛撞击。
This behavior makes it plausible to imagine a fisherman being struck and knocked unconscious by a frantic arapaima. 这种行为很有可能就让钓鱼者被一只绝望挣扎的巨骨舌鱼打昏。
The arapaima is the focus of several conservation projects in South America, including no-fishing reserves and fishing quotas. 因此这种巨滑舌鱼的保护项目在南美逐渐成为焦点，包括休渔期和限定配额的捕捞。
