A sea lion weighing about half a ton went for a leisurely stroll about Balneario Camboriu, Santa Catarina on Saturday.
The animal came out of the sea, crossed the sand and landed in the middle of Atlantic Avenue, one of the city's busiest.
The Municipal Guard and firefighters were called and the street closed for 20 minutes.
Some onlookers threw water over the animal to try to help him. According to a biologist from the Department of Environment, the animal probably came out of the sea to rest. One hour and fifty minutes later, he returned alone to the sea.
