Pink dolphins, also known as Amazon River dolphins or Inia geoffrensis, are fascinating freshwater mammals found primarily in the Amazon and Orinoco river basins. Known for their rosy hue and high intelligence, these creatures have adapted impressively to their environment, especially in their dietary habits.
So, what do pink dolphin eat? Let’s explore their feeding patterns, prey types, and how their behavior differs from marine dolphins.

The Unique Diet of Pink Dolphins
Carnivorous Appetite in the Amazon Basin
Pink dolphins are opportunistic carnivores, feeding on a wide variety of aquatic animals. Their primary food sources include:
- Fish (like catfish, piranhas, and tetras)
- Crustaceans
- Small turtles
They have been observed consuming more than 40 species of fish, showcasing their dietary diversity. Unlike marine dolphins, Amazon River dolphins often forage near the riverbed, using echolocation to locate prey in murky waters.
Seasonal Changes in the Dolphin Diet
During the flood season, when rivers overflow into forested areas, pink dolphins swim among submerged trees to find prey. Their diet becomes richer and more varied during this time. In the dry season, however, their food choices are limited to river fish.
This seasonal shift in the dolphin diet demonstrates their incredible adaptability to environmental changes.
How Do Pink Dolphins Hunt?
Pink dolphins rely on echolocation – a biological sonar – to detect the location, shape, and movement of prey in turbid waters. Their flexible necks give them an edge over other dolphin species, allowing them to maneuver around obstacles like tree roots and fallen branches.
They use different techniques for hunting:
- Bottom feeding to find fish hiding in the riverbed
- Chasing small fish in shallow waters
- Cooperative feeding with other dolphins during flood seasons
Do Pink Dolphins Eat Fish and Crustaceans Only?
Primarily, yes. When people ask what does a dolphin eat, the typical answer is fish. For pink dolphins, fish remain the dominant food source, but they don’t limit themselves. Their dolphin diet also includes:
- Crabs and shrimp in shallow regions
- Small freshwater turtles (swallowed whole or bitten apart)
- Occasionally aquatic snails or mollusks
This versatility makes them highly effective predators in river systems with fluctuating biodiversity.
How Much Does a Dolphin Eat Per Day?
On average, an adult pink dolphin eats about 2.5% to 5% of its body weight daily. For example, a 100 kg dolphin may consume up to 5 kilograms of food per day.
This high intake is necessary to fuel their metabolism and maintain their energy levels in dynamic aquatic environments. It’s important to note that pink dolphins do not eat ice or anything non-biological – contrary to some online myths.
Are Pink Dolphins Dangerous? Do They Eat Humans?
No, pink dolphins do not eat humans. They are non-aggressive towards humans and typically avoid contact. While they are carnivores, their prey is limited to small aquatic animals they can capture and swallow.
The misconception that a dolphin eat human likely arises from misunderstandings or fictional portrayals. In reality, these dolphins are curious but not dangerous.
Where Are Pink Dolphins Found?
Pink dolphins inhabit freshwater ecosystems across:
- Amazon River (Brazil, Peru, Colombia)
- Orinoco River (Venezuela)
- Madeira River basin
They prefer shallow tributaries, lakes, and floodplain regions rich in fish populations.
Conclusion: A Specialist Predator of the Amazon
Understanding what do pink dolphin eat sheds light on how these incredible creatures have adapted to the complex and ever-changing Amazon River system. Their diet is rich, versatile, and crucial to maintaining balance in their aquatic ecosystems.
Whether you’re a wildlife enthusiast or a student of marine biology, learning about their feeding behaviors offers a glimpse into the survival strategies of freshwater dolphins. Unlike marine dolphins, pink dolphins show remarkable hunting strategies that help them thrive in dynamic, often murky habitats.
