Orcas live and travel in pods, which are groups of ten to twenty animals – this is not new information. However, researchers in Russia recently spotted superpods, groups of up to 100 killer whales. These meetings last anywhere from a few hours to a half day and are characterized by common social behaviors – mating, flipper rubbing, synchronized swimming – but to a higher degree than typically observed. What do these social clubs mean and why do they matter? They may simply be another avenue to socialize. Since their large numbers may actually scare off prey, they don’t seem to be an effective way to hunt. Perhaps most importantly, they may be a chance for whales from different pods to meet up and check out potential mates. With calf mortality rates as high as 50 percent in the first six months, any research into understanding orca reproduction is critical in maintaining healthy populations.
