Is whale sperm any bigger than human sperm? : askscience
Description:If human sperm are microscopic, then are blue whale sperm larger? If so how large are they? Gary McLoud, Wiley City, Washington, USA Blue sperm whales have only become as large as they are in response to long-term exposure to environmental factors - long-term, but really quite short-term compared to how long their kind, including their ancestors, have been around.
