How to identify whales
Estimate the whale's size.
You may only see part of the animal, so figuring out its length can be difficult. Try to compare it to the length of a nearby object, such as a boat.
Estimate the whale's general size range, such as 10 to 20 ft (3.0 to 6.1 m). For example, animals under 10 ft (3.0 m) are probably dolphins or porpoises.
