When people think of dolphins, they often imagine friendly, intelligent marine creatures gliding gracefully through the ocean. But beneath their playful image lies a well-adapted predator. So, what animals do dolphins eat? The answer depends on the species, habitat, and even age of the dolphin. From fish and squid to crustaceans and octopuses, dolphins have a diverse diet that supports their high intelligence and energy demands.
In this article, we dive deep into the facts about dolphins, their feeding behavior, preferred prey, and how their diet varies across species and developmental stages.

Understanding Dolphin Diets: General Feeding Patterns
Dolphins are carnivorous marine mammals that primarily consume meat-based prey. They rely heavily on echolocation to hunt, especially in murky or deep waters. While some species are generalists, eating a wide variety of sea life, others are more specialized.
Key Facts About Dolphin Diets:
- Dolphins consume 3% to 10% of their body weight in food daily.
- Most dolphins feed several times a day.
- Prey selection is based on availability, habitat, and season.
Primary Prey: What Do Dolphins Eat in the Wild?
1. Fish
This is the most common food source for dolphins. Species like herring, mackerel, cod, and sardines are rich in proteins and easily catchable by groups of dolphins using cooperative hunting.
2. Squid
Squid is particularly favored by deep-diving dolphin species. For example, Risso’s dolphins feed predominantly on squid.
3. Crustaceans & Octopuses
Some dolphins eat crustaceans such as shrimp, especially those in shallow estuaries and bays. Pink dolphins, also known as Amazon River dolphins, consume a wider range of animals including freshwater crabs.
4. Cephalopods & Small Marine Mammals
In rare cases, dolphins may prey on small cephalopods or even other smaller marine animals like cuttlefish or juvenile seals, although this is more observed in orcas (killer whales, which are technically dolphins).
Diet by Species: What Animals Do Different Dolphins Eat?
Bottlenose Dolphins
One of the most studied dolphin species, bottlenose dolphins mostly eat fish and squid. Their flexible diet includes over 50 fish species and they often use tools, like sea sponges, to uncover hidden prey on the seafloor.
Pink Dolphins (Amazon River Dolphins)
Pink dolphins inhabit freshwater ecosystems and have a more varied diet. They eat over 40 different types of fish, along with turtles and freshwater crustaceans.
Orcas (Killer Whales)
Although technically part of the dolphin family, orcas have a top-predator diet including seals, seabirds, and even large whales depending on their sub-group.
What Do Baby Dolphins Eat?
Baby dolphins, also known as calves, consume only their mother’s rich, fatty milk during the initial months after birth. Dolphin milk is specially designed to promote rapid growth and development. The weaning process may take up to 18–24 months, during which time the young dolphin gradually starts consuming solid prey like small fish.
Dolphin Fun Facts About Their Feeding Habits
- Dolphins don’t chew their food. They swallow fish whole, headfirst to avoid scales or fins getting stuck.
- They sometimes use bubble nets or herding techniques to trap schools of fish.
- Dolphins can coordinate in teams to corner prey, demonstrating advanced social intelligence.
- Certain dolphins are known to beach themselves temporarily to catch stranded fish, a risky but effective feeding behavior.
Conclusion: The Science Behind Dolphin Diets
Understanding what animals dolphins eat gives us deeper insights into their ecological role as apex predators in the ocean. Their diet not only reflects their physical adaptations but also their behavioral complexity. From cooperative hunting to tool use, dolphin facts related to feeding highlight their intelligence and versatility. Whether it’s the dolphin fun facts of bubble net feeding or the detailed dietary preferences of different species, dolphins continue to amaze marine biologists and ocean enthusiasts alike.
Frequently Asked Questions (FAQs)
1. What do baby dolphins eat?
Baby dolphins rely on their mother’s milk for nutrition. As they grow older, they are gradually introduced to fish and other small prey during the weaning process.
2. What do dolphins eat?
Dolphins eat a variety of prey including fish, squid, crustaceans, and sometimes small marine animals. Their diet depends on their species and environment.
3. What do bottlenose dolphins eat?
Bottlenose dolphins typically consume fish, squid, and sometimes shrimp. They are known for their smart hunting techniques and adaptable diet.
4. What do pink dolphins eat?
Pink dolphins eat freshwater fish, crabs, turtles, and occasionally small river mammals. Their diet is more diverse due to their Amazonian habitat.
5. What type of fish do dolphins eat?
Dolphins eat fish such as mackerel, herring, cod, and sardines. Species preference depends on what’s available in their natural environment.
