an Australian lizard (= a type of reptile) that has a large pocket of skin covered in spines (= sharp parts) on its throat that can swell and change colour when the creature is threatened or about to attack

Like other species of Bearded Dragon, this lizard relies on trying to appear larger and spikier than it really is to any potential predator. 和其他种类的鬃狮蜥一样，这种蜥蜴也试图在潜在的天敌面前显得比实际更大更尖。
