An excerpt from the article 16 facts about Basking shark

Due to its slow growth, long gestation period, low reproductive rate and late sexual maturity, the species is not able to recover quickly, so it was deemed necessary to surround it with protection. The species was added to the Red List of Threatened Species in 2005. It is currently classified as endangered.
