The largest whales (blue whales) weigh 100 to 150 tons.
Blue whales can produce over 40 gallons of sperm .
Blue Whales are the largest known species of animal ever known to man. Sperm whales are around 20 meters long while blue whales can be around 30 meters long and weigh twice as much as sperm whales.
A Blue Whales brain can weigh up to 1 ton, but even with that big of a brain they still are not the most intelligent animals. They are still very intelligent just a little slow on the thinking side of things.

Killer Whale - Killer whales usually travel in larger groups and they are a lot faster and more agile. Sperm whales also aren't used to groups of animals attacking them because they are generally deep in the sea where they have no predators and there aren't many animals. Also, killer whales have better eye sight because they use it more while sperm whales are usually in pitch black water where they rely completely on echolocation. Calves and small female groups are at risk, male bull sperm whales are not: The bull sperm whale is much bigger than a killer whale. The bull can grow up-to 65ft and way over 60 tons, have over 40 large 't-rex' style teeth on their bottom jaw, and can become incredibly aggressive when threatened. Their massive head act as the perfect battering rams, and their huge tail flukes can decimate a pod of orcas. Hence orcas rarely engage combat with large bulls sperm whales, as there are plenty of other fish in the sea: ie lower risk, higher reward prey items around
Adult males can get to be 45 to even a giant 59 feet, but females are much smaller(36 feet). Male sperm whales weigh in to 35 or even 45 tons! Again, females are much smaller, and will weigh in to 13 or 14 tons. Calves,(babies)however, have not been studied.
