You’ve likely seen the photos—an arapaima, mouth agape in what appears to be a toothy grin. This image inspires both wonder and perhaps a touch of fear. But before we imagine this fish plotting global domination, let’s uncover the real story behind that “smile.”
The arapaima’s impressive grin isn’t about happiness; it’s about survival in the murky depths of the Amazon River. Unlike most fish, the arapaima’s lower jaw protrudes, creating a permanent “smile.” Add a bony tongue, and you have a recipe for a powerful bite.
This unique anatomy suits the arapaima’s predatory lifestyle. As ambush predators, they rely on stealth and lightning-fast attacks. That protruding jaw allows them to open their mouths incredibly wide, generating a vacuum that sucks in unsuspecting prey.
And those glowing eyes in photos? Simply a trick of the light. The arapaima’s eyes are adapted for the low-light conditions of the Amazon. A special reflective layer helps them see, and when light hits just right, it creates a spooky glow.
But the arapaima is much more than a toothy grin and glowing eyes. As one of the planet’s largest freshwater fish, it plays a crucial role in the Amazonian ecosystem, helping control other fish populations. They are also a food source for indigenous communities who have lived alongside these giants for centuries.
Sadly, the arapaima faces serious challenges. Overfishing and habitat loss threaten these incredible creatures. Understanding the truth about the arapaima—beyond viral photos—is the first step toward protecting them.
Can Humans Eat Arapaima?
Yes, Arapaima is edible and considered a delicacy in the Amazon River basin. Despite its predatory nature, it poses no threat to humans as food and is often compared to cod or halibut. Local communities typically prepare Arapaima by grilling, baking, or frying it.
While the exact nutritional content needs further research, Arapaima is likely a good source of protein and omega-3 fatty acids, much like other fish species.
However, Arapaima’s conservation status requires responsible consumption. Choosing sustainably sourced Arapaima from aquaculture farms can help protect wild populations.

Is It Legal to Own an Arapaima in Indonesia?
The answer is a resounding no. The Indonesian government, through the Ministry of Marine Affairs and Fisheries (Permen KP), issued Regulation Number 19 of 2020, strictly prohibiting the ownership of Arapaima throughout Indonesia.
This ban stems from the Arapaima’s invasive potential. As a large, predatory fish, its introduction to Indonesian waterways could be disastrous for native species.
“So there were residents who kept them. I don’t know the exact number, but it was more than 10. Then, during a flood, their pond broke and all the fish escaped,” stated Asep Ridwan, Lurah Paminggir, regarding an Arapaima escape incident.
While Arapaima ownership is out of the question, Indonesia boasts a wealth of beautiful and unique fish species perfect for aquariums. It’s our responsibility as fish enthusiasts to safeguard Indonesia’s aquatic ecosystems, and that includes preventing the introduction of invasive species like the Arapaima.
Is the Arapaima Aggressive?
The Arapaima has a somewhat fearsome reputation due to its size and aggressive nature. Growing up to 3 meters long—longer than a car—and possessing formidable biting power, it’s no wonder the Arapaima reigns supreme in the Amazon River.
While generally peaceful in captivity, its predatory instincts remain strong. Their large size and rapid reproductive rate make them a danger to native ecosystems, as they could outcompete local fish for resources and disrupt the natural balance.
The presence of Arapaima in Indonesian waters, despite the ban, raises concerns about the effectiveness of current regulations and public awareness campaigns. This highlights the need for stricter enforcement and ongoing education to prevent the further spread of this potentially invasive species.
