According to wikipedia.org, The arapaima, pirarucu, or paiche are any large species of bonytongue in the genus Arapaima native to the Amazon and Essequibo basins of South America. Genus Arapaima is the type genus of the family Arapaimidae. They are among the world’s largest freshwater fish, reaching as much as 3 m (9.8 ft). They are an important food fish. They have declined in the native range due to overfishing and habitat loss. In contrast, arapaima have been introduced to several tropical regions outside the native range (within South America and elsewhere) where they are sometimes considered invasive species. Its local name, pirarucu, derives from the indigenous words for “pira” meaning “fish” and “urucum” meaning “red”.

Whale Sharks in Oslob, Cebu vs. Arapaima in Amazon
Now that you’ve seen the video, imagine how awesome it is to watch or even swim with it if it was swimming with the whale sharks in Oslob, Cebu too… Just even probably 10 – 20 of it, though it is really impossible since it is only found in Amazon and only lives in fresh water.
