The Arapaima: The Prehistoric Fish That Inhabits the Amazon

The arapaima, or pirarucu as it is known in Brazil, is one of the oldest fish living on Earth. This impressive fish has managed to survive for millions of years, enduring extinctions and significant environmental changes. We will dive into fascinating facts about its ancient history, adaptations, and the ecological importance it holds for the Amazon basin.

A Living Fossil

The arapaima has an evolutionary history dating back over 23 million years, making it a true living fossil. Over this long period of time, its biology has changed very little, suggesting that its original evolutionary traits were so successful that they hardly needed modifications to survive to the present day.

Adaptation to a Challenging Environment

One of the reasons the arapaima has survived for so long is its remarkable ability to adapt. Unlike many fish, this freshwater giant can breathe air. This allows it to live in stagnant or low-oxygen waters where other fish cannot thrive. During the dry season, when water levels are low, the arapaima can survive in small, muddy ponds as long as it can surface to breathe.

Reproduction: Synchronized with Nature

The arapaima’s reproductive cycle is synchronized with the Amazon’s rainy season. During the wet season, rivers overflow and create lagoons and pools in the forest. It is in these spaces that the arapaima lays its eggs, ensuring that the young have enough room and food. Interestingly, unlike other fish, both parents protect the young for several months.

Cultural and Economic Importance

Threats and Conservation

Despite its resilience throughout history, the arapaima faces current threats due to over-exploitation and habitat loss. Many conservation initiatives are working with local communities to ensure that this prehistoric fish does not disappear from the face of the Earth.

The arapaima is much more than just a fish; it is a survivor of Earth’s history. Its ability to adapt, its cultural significance, and its evolutionary history make it one of the most extraordinary fish in the world. Conserving this fish is crucial to maintaining the biodiversity and ecological balance of the Amazon.
