According to scientists, toxic algae led to the deaths of two dozen whales that washed up on the shores of British Colombia and Alaska. Studies also showed that the Pacific Ocean has a warmer than normal patch of water that created the toxic algae bloom.

A University of British Colombia professor, Andres Trites, said that algae hold a neurotoxin that has poisoned small fish, which are the whales' food. Andres said that in case it passed on in huge amounts to mammals or birds, then it can lead to seizures, brain damage, and death. It can be said that the whales suffered food poisoning.

Since May 2015, 30 sea creatures, including 11 fin whales, 1 gray whale, 14 humpbacks, and 4 unidentified cetaceans have been found dead near Alaska's shores. In British Colombia, 4 humpback whales were found dead five months later.

While talking to CTV News, Trites said, "We can rule a few things out by having inspected their bodies to rule out things such as starvation, any signs of disease, any signs of having been hit by ships or caught by fishing gear".

He added that the deaths are a warning that climate change has been playing a part in affecting lives on land and the sea. This year, three times more whale deaths have occurred in comparison to years before, which is an ominous sign.

Despite the theory given by Trites, scientists haven't confirmed that the toxic algae were behind the deaths since the bodies weren't fresh enough to detect noxious substances. According to them, it is going to be an unsolved mystery.
