Marine FAUNA


WHALES

Maximum visitors of Marina Patagonia, the Southern Right Whales (Eubalaena australis) never ceases to amaze with their jumps and spins off the coast near San Antonio Bay. Robust and up to 40,000 kg of weight, they move gracefully in an ocean that kindly keeps them and allows us to contemplate and accompany them in their spring visit.
Declared as a “National Natural Monument”, with its 15 meters is certainly a vivid memory of the calm sea power that thrills and whose image will be forever in your memory.
Chance of sighting. HIGH (in winter - spring)



SEA LIONS

Abundant in these Patagonian waters and with several breeding colonies in Río Negro costs, is easy to interact with South American Sea Lions (Otaria flavescens) and South American Fur Seal (Arctocephalus australis). They are often found in small groups swimming, feeding or just frolicking in the water, but also can be seen in a small colony on our tour in the Bay.
Chance of sighting. HIGH



SEA BIRDS

The sea is an abundant food source and so there is a great diversity of birds that have it as their permanent or temporary habitat. During our tours you will be able to contemplate the variety of shapes and styles to which birds have adapted to exploit the virtues of the sea and its strength to withstand the harshest days. Penguins, gulls, grebes, cormorants and albatrosses will definitely be around, either solitary or joining Dolphin herds that found schools of food near the surface.
The dedicated amateur will understand the value of getting a bird guide to deepen the knowledge of the great bird fauna seen in the tour.
Chance of sighting. VARIABLE (depending on the species)



THE HIDDEN FAUNA

The nearby seabed. In San Antonio Bay and San Matías Gulf coasts inhabits a peculiar fauna which is abundant and very close to us, sometimes just inches under the water, and it deserves to be revealed to the curious spirits who know how to admire the diversity life. Among these organizations we highlight the Patagonian Seahorse (Hippocampus patagonicus) and Purple Clam (Amiantis purpurata). Both species, with tropical origins, were able to adapt and live at this point thanks to the thermal benefits of the Bay and surrounding area, which allows them to reproduce and form stable populations.
On this coast we can find abundant populations of Patagonian Octopus (Octopus tehuelchus), a small octopod which together with the purple clam are caught by an artisanal fishery, giving us some of the culinary delights that can be enjoyed in the area.
On the rocky reefs of these shores we can also find a variety of fish (Brazilian Sea Bass, Argentinean Sand-perch, Patagonian Blenny, Silver Porgy, rays and more), which together with the most colorful crabs, sponges, snails, oysters and small mussels complete a magical setting awaiting to be discovered.
Chance of sighting. VARIABLE (depending on the species)


Occasional visitors: The luckiest visitors were able to admire in our tours Long-finned Pilot Whales, Minke Whales, Crabeater Seals, Hammerhead Sharks and Sperm Whales, among others.
Chance of sighting. VERY LOW



DOLPHINS

Bottlenose Dolphins. Locally known as “Toninas”, Bottlenose Dolphins (Tursiops truncatus) are often found in the calm waters of Bahia San Antonio and sometimes on the coast of Las Grutas, swimming freely, jumping and surprising for its considerable size, up to 3 meters.
Given the opportunity to sight them forget about the camera and enjoy the show. They typically show themselves from a distance for a few moments and then swim quickly to other destinations, accompanying the tide.
Chance of sighting. MEDIA

Common and Dusky Dolphins. Out of San Antonio Bay, following the coast line of Villarino and La Conchilla beaches and entering San Matías Gulf, we can see from very close surprising and abundant herds of tens of Common Dolphins (Delphinus delphis) playing with each other and with the wake that the boat leaves behind when moving forward. These dolphins are smaller than the Bottlenose Dolphins, reaching a length of 2 meters and forming flocks of up to 400 individuals.
The keen observer can distinguish between them some individuals of Dusky Dolphins (Lagenorhynchus obscurus) sharing the journey and fun with the others.
Chance of sighting. HIGH

Orcas. The most attractive and large dolphins, their greatly undeserved bloodiness reputation is only compared with the beauty of its majestic black and white design. Despite the number of Orcas (Orcinus orca) in northern San Matías Gulf is about a dozen, some visitors have had the opportunity to watch these highly migratory species in action. Be sure to ask the captain of the boat to tell you his encounters and experiences of years with these magnificent animals.
Chance of sighting. LOW
