Elephant seals are a sexually dimorphic species of marine mammal that lives off the coast of California. The females, which weigh around 1000 lbs, are much smaller than the males, which may weigh up to 5000 lbs. Suppose that scientists measured the weight of three adult female elephant seals and their female offspring.
