Average size of a 5 yearold dolphin?

The average size of a 5-year-old dolphin can vary depending on the species. For example, bottlenose dolphins typically reach lengths of about 8 to 12 feet and weigh between 300 to 1,400 pounds by this age. In contrast, smaller species like the common dolphin may be slightly smaller, while larger species, such as orcas, can be much bigger. Overall, a 5-year-old dolphin is generally well on its way to reaching its full adult size.
