The North Atlantic right whale, nicknamed Chiminea, was seen swimming near Folly Beach, just miles from Charleston.

The right whales, which can also be found off the coasts of Georgia and Florida, seem to be increasing slowly in number. The number of living whales in 2014 was two times the number reported in 1996. On Thursday, the National Oceanic and Atmospheric Administration said biologists spotted three new right whale calves off the coast of Georgia in just two days.

All right whales are identified and cataloged using numbers, according to the organization.
