Cyanobacteria

As of March, about 330 dead elephants were found in Okavango and its surroundings, the initial assumption that the elephants were killed by poachers was disproved since the elephants were not robbed. A second assumption was that the death was caused by the anthrax virus, but it turned out that this was not the cause of death either, other animals were not harmed. The authorities investigated the deaths and apparently found the culprit, Cyanobacteria.
