A population of highly endangered Southern Right Whales (Eubalaena Australis) uses the clear and protected waters of the Nuevo and San José gulfs to mate and give birth to their calves (baby whales). The estimated weight for an adult Southern Right Whale is 35 to 55 tons, with a length of 39 to 52.5 feet (12 to 16 meters). The weight of a newborn calf is 3 tons and its length is 13 to 14.5 feet (4 to 4.5 meters).

Most of the world's whale species show ventral grooves and a dorsal fin, but the Southern Right Whale lacks both. The top jaw is long and thin, measuring a quarter of its total body length. Callosities on their backs and on the sides of their heads are one of the distinctive characteristic of the Southern Right Whale. Each whale has a unique callosity pattern which does not vary and therefore makes it possible to perfectly identify them, as it is done by scientists. Callosities are to this whale are as fingerprints are to humans.

On the top of their heads they possess two external blowholes instead of one as most whales do. One of the most outstanding characteristics of the Southern Right Whales is the way in which they exhale two columns of air containing water particles that emerge forming a “V” which can be observed from some miles or kilometers away.

The boat that you will navigate in has been equipped with the latest security equipment in order to be able to safely enjoy this unique experience. Moreover, boat captains are trained and qualified to make a close approach and ensure an excellent whale watching experience without disturbing or hurting the whales. For example, engines are turned off when whales approach and captains avoid direct approaches to whales.

One of the most distinctive characteristic between the Southern Right Whale and other Whales species is that it is very friendly and playful, specially the young whales. The Southern Right Whale is known for its tameness, slow movements and especially because of its curiosity. It is definitely a safe animal to approach, even when it comes close enough to touch the boat. Right whales was the name chosen for this whales by the whale hunter, as they thought this whale was the "right whale to hunt", as they are very easy to approach to, the live close to shore, provided large quantities of valuable oil, meat and whale-bone, and conveniently floated when dead.
Their friendly and curious character, as opposite from other whales, surprises travelers who are usually deeply touched with the sociable and curious behavior of these friendly whales.

While you will definitely see a lot of dorsal fin movements and breathing, to see a whale jump is the ultimate goal and not to be missed on camera. The surface activities of the southern right whale include:

• Breaching: leaping clear out of the water, spinning and then landing with a huge splash.
• Lobtailing: raising the tail and then crashing it down on the water.
• Slapping: raising a flipper and slapping it on the water.
• Headstanding: a vertical position with tail held high in the air.

The sailing will last one hour and fifteen minutes. We then return back to port.
