通称：蝠鲼
物种：蝠鲼种
时代：渐新世早期-全新世
食性：食肉
性情：好战
野生
这又是一个生物进化超越了其历史特性的例子。所有的事实都指向这种生物是咸水蝠鲼，但这种蝠鲼进化出了在岛上的河流和浅滩里游动的能力，就像它们在开阔海洋中游动一样。也许一开始岛上有两种蝠鲼，但多年的杂交使它们的血统融合了。 蝠鲼一般来说是温顺的，它仅因为以浮游生物为食而被当做食肉动物。 幸运的是，蝠鲼通常不好战，除非它被激怒了。 它的尾巴难以置信的尖锐，并可以轻易的刺穿兽皮和盔甲。
家养
虽然蝠鲼不是岛周围最快的游泳健将，但它却是小型海洋坐骑里最为致命的。相比速度更重视打击力的部落通常会驯养一大群骑乘用蝠鲼。它短暂跳出水面的能力也使它具有避免战斗的炫耀技巧。 它可以迅速刺穿没有防备的生存者的胸膛来突袭致胜！因此，许多部落用它作为他们缓慢水生驼货生物的护卫。
Common name: Manta
Species: Manta mobula
Time: Early Oligocene-Holocene
Diet: Carnivore
Temperament: Aggressive
Wild
Here is another example of a creature that seems to have evolved beyond its historical traits. Everything points to this being a saltwater ray, but Manta mobula has developed the ability to swim into the island's rivers and shallows, as well as through the open ocean. Perhaps there were originally two types of ray on the island before, but years of interbreeding combined their lineage. Normally docile, Manta mobula is a carnivore only in that it naturally consumes plankton. Fortunately, Manta mobula is usually not aggressive, unless encroached. Its tail is incredibly sharp, and can pierce through thick hide and armor with ease.
Domesticated
While not the fastest swimmer around the island, Manta mobula is among the deadliest of small ocean mounts. Tribes who value striking power over speed often keep large schools of Manta to ride. Its capability to briefly leap out of water provides it a showy tactic for avoiding combat as well. A quick jab through the heart of an unsuspecting survivor can easily take them by surprise! Thusly, many tribes use it as an escort for their slower cargo-carrying swimmers.
