Immature Blue Whale washes up dead on coast of Nova Scotia.

A juvenile Blue Whale, Balaenoptera musculus, has been found on the coast of Nova Scotia. The Whale, judged to be a juvenile as it is only 18.8 m in length (compared to around 30 m for adults of the species) was first sighted Sutherland's Cove, about six kilometres north of Port Hawkesbury on Wednesday 18 September 2019. It was originally hoped that a necropsy (animal autopsy) could be performed on the Whale, as there have been concerns about Whales in the area being injured or killed by ship strikes or after becoming entangled in abandoned fishing nets, but Fisheries and Oceans Canada have now ruled this out, due to the remote location of the corpse and its advanced state of decay.

Blue Whales are the largest animals living on Earth today, and are larger than any known animal in the fossil record, with adults reaching around 30 m in length (some Sauropod Dinosaurs are thought to have been slightly longer, but much less bulky). The species was hunted to the brink of extinction during the twentieth century, before a moratorium on hunting the species was introduced in 1966, since when the species has begun to recover. There are currently thought to be somewhere between 10 000 and 25 000 Blue Wales living today, with the species being classified as Endangered under the terms of the International Union for the Conservation of Nature’s Red List of Threatened Species

I got tested at first when i first had the virus and i My doctors prescribed Antiviral medicine for me which really helped me a lot in suppressing the virus. I finally got cured using herbal protocol ordered from Dr Onokun an African herbalist. I used his Products and it completely fought the virus and was tested negative.
