What is the Difference Between Orca and Dolphin?

Orcas and dolphins are both marine mammals, but they belong to different species and have distinct physical characteristics and behaviors. Here are some key differences between them:

1. Size: Orcas, also known as killer whales, are the largest members of the dolphin family, growing up to 6-8 meters long and weighing up to 6 tons. Dolphins, on the other hand, range from 2-4 meters in length and weigh between 100-200 kg.
2. Appearance: Orcas have a distinctive black and white coloration, a stocky, muscular build, and a rounded head. Dolphins are more sleek and slender, coming in a variety of colors and patterns.
3. Diet: Orcas are apex predators, feeding on fish, seals, and even other dolphins. Dolphins primarily consume jellyfish, squid, and schools of fish.
4. Dorsal Fin: Orcas have a large, erect dorsal fin, while dolphins have a smaller, more curved dorsal fin.
5. Habitat: Orcas live in both saltwater and freshwater environments, while most dolphin species prefer the shallow parts of tropical and temperate oceans.

Both orcas and dolphins are highly intelligent and known to travel in social groups, exhibit playful and friendly behavior, and utilize hunting techniques like echolocation.
