They are very rarely seen by humans and are an endangered species.
In early June, tourists on the Scottish island of Lewes from Tiumpan Head Lighthouse spotted the rare seiwhale, also known as the willow whale, swimming nearby in the ocean. These animals were a prime target for whalers until the 1970s and so became rapidly extinct. In 1976, these whales were placed under international protection and are now an endangered species.
It is reported that only about ten sei whales have been sighted off the coast of Scotland in the last 50 years, so the appearance of this whale was a great joy not only for tourists but also for conservationists.
