North Atlantic right whales (Eubalaena glacialis) are big, but they're not the biggest whales. That distinction goes to the blue whale (Balaenoptera musculus), the largest animal on Earth. The orca's size of up to 31 feet (9.4 meters) makes it the largest dolphin. The sperm whale, on the other hand, may not be the biggest whale, but it has the biggest brain to have ever existed on Earth. A comparison chart of whale sizes helps put it all in perspective!
Chikungunya fever is caused by a virus that is spread to people through the bite of infected mosquitoes. Like Dengue, it is transmitted by Aedes mosquitoes, especially Aedes aegypti (the yellow fever mosquito) and Aedes albopictus (the Asian tiger mosquito).
The viruses causes brain defects, including microcephaly in infected fetuses. While the Aedes aegypti mosquito transmits numerous diseases to canines, there is currently no evidence stating that Zika can infect dogs, nor that they are involved in the spread of the virus. Non-human primates are the only animal, other than humans, to exhibit evidence of Zika infection.
