On Monday, March 5, a group of locals and tourists united to save an estimated 30 dolphins from beaching themselves. The improvised rescue took place on the shores of Arraial do Cabo, Brazil, just north of the city of Rio De Janeiro.

While entire pods of dolphins are known to sometimes beach themselves, the occurrence is still not fully understood by experts. According to MSNBC, common dolphins will sometimes strand themselves in large numbers due to their tight social structure, even if they’re not sick. Luckily, this pod was in good health and managed to swim back out to sea with a little help from friendly beach goers.
