Two new North Atlantic right whale calves were spotted off the coasts of Georgia and Florida. This is exciting news for the critically endangered species. There are only 366 individuals left and every new whale counts. The population has taken a dive in recent years due to fatal encounters with ships. The mother-calf pairs are more likely to be hit because they float at the surface. The number of new births has also been low. Last season, only 10 calves were born. Experts says the population needs double that to avoid extinction.
