Even though orcas are often called killer whales, they belong to the dolphin family, making them the largest members.
Orcas range from 5.5 to 9.8 metres in length, with males generally larger than females, and they can weigh up to 5,500 kg.
It is possible through features like their dorsal fins, saddle patches, and any visible scars they may have.
Orcas are formidable predators, known to hunt whale species much larger than themselves.
Their lifespan can extend up to 90 years, with females typically outliving males.
Pregnancy for orcas lasts approximately 17 months, and they usually give birth every 3-5 years, though intervals between successful births can be as long as a decade.
Communication among orcas involves a variety of sounds including clicks, whistles, pulsed calls, squeals, squeaks, and screams.
