How long or tall is the dolphin?

Dolphins vary in size depending on the species. For example, the common bottlenose dolphin typically reaches lengths of 8 to 12 feet (2.5 to 3.6 meters) and can weigh between 300 to 1,400 pounds (136 to 635 kg). In contrast, the orca, or killer whale, can grow up to 20 to 26 feet (6 to 8 meters) long and weigh as much as 6 tons (5,443 kg). Overall, dolphins exhibit a wide range of sizes across different species.
