How long do whales grow?
they belong to the same group (Cetacea) but they are not exactly the same thing. Did you know that Killer Whales (Orcas) are a type of dolphin. A difference is their size.The biggest dolphin is the Orca which can grow to 8m long, while the [[blue whale]] can grow to 30m. mOST TRUE Whales are baleen although toothed whales are sometimes classed as dolphins.
Depends on if you measure by weight and length. Blue whaes are heavier than even the biggest dinosaurs, but there might have been dinos that were taller. No. According to Wikipedia, the free encyclopedia, it says that the longest dinosaur is Amphicoelias, which can grow up to 40-60 meters (131-196 ft) long. But blue whales can grow up to only 33 meters (110 feet) long. Even Supersaurus can grow up to 35-40 meters (114-131 ft)…
Adult Male Sperm Whales can be as long as 20 meters. The average size is around 17 meters and they weigh 40 tonnes or more. Adult Female Sperm whales are on an average 11 meters long and weigh around 14 tonnes. They are one of the largest Whale species in the world. Sperm whales can grow up to 60 feet as males, while females can be 40 feet.
Humpback whales grow to be about 52 feet (16 m) long, weighing 30-50 tons (27-45 tonnes). The females are slightly larger than males, as with all baleen whales. The four-chambered heart of the average humpback whale weighs about 430 pounds (195 kg) - about as much as three average adult human beings. http://www.enchantedlearning.com/subjects/whales/species/Humpbackwhale.shtml
A newborn sperm whale is around 4 meters in length and weighs approximately 1000 kilograms or more. They grow very fast and to huge sizes. Adult Male Sperm Whales can be as long as 20 meters. The average size is around 17 meters and they weigh 40 tonnes or more. Adult Female Sperm whales are on an average 11 meters long and weigh around 14 tonnes.
Killer whales are medium sized cetaceans (all whales are cetaceans, but not all cetaceans are whales--Orcas are more closely related to dolphins). The males grow up to an an average size of 30 feet or more and the females grow up to be an average size of 18 feet long. The average weight of a killer whale is about 9 tons. Nine metric tons is 9,000,000 grams. Nine imperial tons is 8,164,662.66 grams.
