1. What are the types of barnacles that adhere to whales and do they hurt the whale?

The types of barnacles are called Acorn, Goose and Stalked Barnacle. They are not in a symbiotic relationship. The barnacles are actually parasites living on the skin of the whale. The barnacles do not attach to fast-moving things such as dolphins and sharks.

2. Among the whale species, which is the most antique?

The Gray whale is the oldest, estimated at living in oceans for 30 million years. It is 15 meters in length. It weighs 36 tons and can live to be 60 years old.

3. Why isn't there more being done to protect the seals?

The Seal Protection Action Group (SPAG) is dedicated to protecting seals and their environment. This is done through education, campaigning, and supporting non-invasive scientific research. We can help the seals by making donations, and getting involved in SPAG efforts.
