WEB DESK: Dolphins, often romanticised as friendly and intelligent marine mammals, possess a surprising and darker side that challenges this popular perception. Beyond their playful antics and apparent affability, dolphins exhibit behaviors ranging from aggressive tendencies to complex social dynamics that may shock those unfamiliar with their full spectrum of behaviors.
Since the iconic TV show “Flipper” first aired in 1964, dolphins have been ingrained in popular culture as symbols of intelligence and grace. However, their interactions with humans and other species reveal a more complex reality. Here are ten intriguing aspects of dolphin behavior that defy their benign image:
Aggression towards humans
Despite their portrayal in captivity as gentle creatures, dolphins can bite and injure humans. Instances include a captive dolphin at Sea World in Orlando biting an eight-year-old girl in 2012, and wild dolphins biting swimmers who enter their territory, sometimes pulling them underwater.
Fatal attacks
Dolphins have been known to attack humans aggressively, sometimes with fatal consequences. In San Paulo, Brazil, in 1994, a dolphin attacked two men who approached it in the water, resulting in one man’s death from internal injuries.
Coordinated hunting techniques
Dolphins exhibit sophisticated hunting behaviors, such as herding fish into tight groups called “bait balls” and using strategic teamwork to maximize their hunting efficiency. In some cases, they even beach themselves to catch prey.

Large-scale hunting packs
While dolphin pods typically consist of 10-15 members, super pods with over 1,000 dolphins have been observed during hunting expeditions, highlighting their formidable collective hunting capability.
Violent feeding habits
Dolphins engage in violent feeding practices, including “fish-kicking” where they use their tails to stun fish, and violent techniques to subdue octopuses, ensuring the safety of their meal.
Murderous tendencies
Unlike most animals that kill for survival, dolphins have been observed killing porpoises and other animals seemingly for reasons unrelated to food, exhibiting behaviors akin to murder.
Infanticide
There are documented cases of male dolphins attacking and killing newborn calves, a behavior that contradicts their image as gentle and nurturing animals.
Aggressive mating rituals
During mating season, male dolphins can exhibit aggressive behavior towards female dolphins, including physical assaults and coercive mating tactics involving multiple males ganging up on a single female.
Learning & innovation in hunting
Dolphins are capable of learning and sharing new hunting techniques, such as the practice of “shelling” to catch fish, demonstrating their ability to adapt and innovate within their social groups.
Playful aggression
Dolphins sometimes exhibit aggressive behavior seemingly for amusement, as seen when a group of dolphins surfed towards a paddleboarder in Australia, causing him distress but not harm.
These behaviors challenge the conventional narrative of dolphins as purely benign creatures and underscore their complex social and ecological roles. While they are celebrated for their intelligence and adaptability—traits that have endeared them to researchers and the public alike—dolphins’ darker behaviors reveal a more nuanced understanding of their interactions with their environment and other species.
Understanding these aspects of dolphin behavior is crucial for conservation efforts and for ensuring the safety of both humans and dolphins in shared aquatic environments. By recognizing their complex behaviors, scientists and conservationists can better protect dolphins while promoting responsible interactions between humans and these fascinating marine mammals.
In conclusion, while dolphins continue to fascinate and inspire awe, their darker behaviors remind us of the complexities of animal behavior and the importance of respectful coexistence in our shared natural world.
