Dolphin weight varies from species to species. For the smallest dolphin the weight can be 30 Kg. and the largest species like the orca can weight up to 5 t I hope this helps.
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.
Yes, sadly some species of dolphin are on the endangered list, this is because of people hunting them.
The bottlenose dolphin sometimes forms mixed species groups with other species from the dolphin family, particularly larger species such as the Short-finned Pilot Whale, the False Killer Whale and Risso's Dolphin. They also interact with smaller species, such as the Atlantic Spotted Dolphin and the Rough-toothed Dolphin. While interactions with smaller species are sometimes affiliative, they can also be hostile.
