Mirissa’s offshore waters occasionally host Short-Finned Pilot Whales (Globicephala macrorhynchus), one of the most social and intriguing toothed whales in the Indian Ocean. Known for their strong pod cohesion and intelligence, these whales are less frequently seen than Bryde’s whales, but sightings in Mirissa offer unique opportunities for researchers and whale-watchers alike.
Their presence in Mirissa is supported by warm tropical waters, abundant prey species, and deep offshore habitats, which provide ideal conditions for both feeding and social interaction.
The species recorded in Mirissa is the Short-Finned Pilot Whale (Globicephala macrorhynchus), a small-toothed whale in the dolphin family (Delphinidae) that is well-known for:
These whales are distinct from long-finned pilot whales and are the resident species in tropical and subtropical waters around Sri Lanka.
Short-Finned Pilot Whales are attracted to Mirissa because of:
These factors make Mirissa a reliable site for observing their natural social and feeding behaviour.
Short-Finned Pilot Whales are smaller than sperm or Bryde’s whales but are powerful, robust animals with a distinctive bulbous head.
Their size provides:
Their body structure reflects adaptation for social cohesion and hunting efficiency.
Their dark colour contrasts sharply with Mirissa’s turquoise waters, making surface sightings easier.
These physical traits make them distinctive among offshore whales and dolphins in Sri Lankan waters.
Their coordinated pod movements are a key identification feature.
Dive deep for food using echolocation
Mirissa’s offshore waters provide ideal conditions for both solitary hunting and pod coordination.
While sperm whales can be seen throughout the year, certain seasons offer better conditions for observation.
November to April
May to October
Although sightings are less predictable than Bryde’s whales, experienced guides can locate pods offshore.
Short-Finned Pilot Whales prefer coastal and near-offshore habitats, making Mirissa ideal for observation.
Pod cohesion is critical for hunting, navigation, and social bonding.
Their predictable pod behaviour makes responsible whale-watching feasible.
Yes. They are less common than Bryde’s whales, but sightings occur, especially offshore.
By their bulbous head, dark body, sickle-shaped dorsal fin, and tight social pods.
Yes. They are highly social and usually observed in pods of 10–50 individuals.
Yes, provided whale-watching guidelines are followed and safe distances are maintained.
