Size Comparison of Whales and Dolphins

There are seven species of whales and dolphins common in the Strait of Gibraltar. Some of them are resident and spend the whole year in this area. Others pass the strait on their journeys and can only be seen at certain times of the year.

At sea it is often difficult to estimate the size of the whales and dolphins swimming by. So our graphic will give you an idea on how big these animals really are.
