Amazon Quiz (November 01): Name this fish that is known to launch itself out of the water like a torpedo, and knock fishermen off their boats.
Paraiba
Arapaima
Red-tailed Catfish
Pink Dolphin
Answer: Arapaima
These fish have a modified swim bladder that functions as a kind of lung and dwells in the murky waters of the Amazon. This indicates that they take in air from the surface and use it to take in oxygen. Though not very much, they may use their gills.
The arapaima can reach a length of 15 feet and a weight of 440 pounds. Consequently, along with the beluga sturgeon, mekong huge catfish, gigantic freshwater stingray, and alligator gar, is regarded by the majority of people as one of the largest fish. These are some of the biggest in the globe, albeit it varies on how you define “largest” in certain aspects.
Many other fish are mouth brooders, which means they take in the young and care for them in their mouths until the fish are a little older.
The majority of fish have gastrointestinal tracts that exit to the left of the stomach, which is an odd scientific fact. That’s kind of strange because all other fish—those that aren’t osteoglossiform fish—have intestines that extend to the right of the stomach.
It is quite unfortunate, but the arapaima is vanishing. They have already gone extinct in 19 percent of their area, and until people stop fishing for these enormous fish, their survival is in doubt.
