The southern minke whale is a species of minke whale within the suborder of baleen whales. It is the third smallest baleen whale. While it was first scientifically described in the mid-19th century, it wasn’t recognized as a distinct species until the 1990s. Given that it was ignored by the whaling industry due to its small size and low oil yield, the southern minke was able to avoid the fate of other baleen whales and maintained a large population into the 21st century, numbering in the hundreds of thousands. It has survived to become the most abundant baleen whale in the world.

The orca is the largest member of the dolphin family, and it is probably the most easily recognized of all cetaceans. The most obvious feature is the enormous dorsal fin, which is the tallest and most pointed of any cetaceans. In adult males, it may stand two metres in height, while in females and immature males it is more curved and smaller. They have a striking black and white pattern from throat to abdomen, some of their flanks, and an oval blaze behind the eye white, with the rest mainly black. The huge conical head is pointed with a very slightly rounded beak. Males can reach 7 to 9 metres in length and weigh 3.8 to 5.5 tonnes. Females are noticeably smaller in overall body size, reaching 5 to 7.7 metres length.

This seal species was not discovered until 1823 when Captain James Weddell captured six specimens during his voyage to the South Pole. They are amongst the largest and fattest seals, with proportionately small flippers and heads, and large dark eyes. Both sexes are similar in size and appearance, but females are generally slightly larger, and males have thicker necks and broader heads. They reach 2.5-3 metres and weigh between 400-600 kg. They have a short, dense coat of a dark bluish-grey colour, which is irregularly streaked. They can become browner prior to moult.

The southern elephant seal is the world’s largest seal. It is a heavy-built, long-body seal with proportionately small flippers and some skin folds just behind the head. The dark eyes are large and round. The adults have short stiff hair, usually dark grey dorsally and paler ventrally. Males have squarer and larger heads, with a conspicuous proboscis, while females have more rounded heads with no proboscis. Breeding males may weigh up to a sixth that of a breeding female. Males can grow to 4.5-6.5 metres and 3,700 kg; females can grow to 2.5-4 metres and between 360-800 kg.

These seals have long slim bodies, with an almost serpentine appearance and comparatively large reptilian heads with a long snout, powerful jaws, broad gape and relatively small dark eyes. Fore flippers are rather large, situated near the centre of the body. They are coloured with dark on the back, almost black or blue-grey on the flanks, and paler ventral colouration; a light area variably spotted with darker grey. They have very long canine teeth, with long pointed cusps on the molar teeth. Females are larger than males (3.8 metres and 500 kg compared to 2.8-3.8 metres and 300 kg).

The cape petrel is an unmistakable medium-sized petrel, with a round head and highly distinctive black and white upperparts and upper wings, smaller than the Antarctic petrel. Its speckled appearance has earned its other common name, pintado, which means ‘painted’ in Spanish. The cape petrel has a circumpolar distribution at sea. It has a wide breeding range from the Antarctic continent to the more southerly Subantarctic islands, where it breeds in November and December in loose colonies on level rocky grounds or gravel, and moderately high cliffs.

There is no clear agreement on how many species of cormorants inhabit the southern islands and the Antarctic Peninsula. There could be as many as seven or as few as two surrounding Antarctica, depending on what taxonomic diversity they have. All are reasonably similar, but the Antarctic shag is unmistakable in range because no other blue-eyed shag overlaps with it. They are rather large and have a black and white shag, with a bright blue-eyed ring, with a long wispy black erectile crest.

Giant-petrels are the largest of the petrel family, which make up the order of tubenose or procellariiform seabirds, along with albatrosses, shearwaters, storm petrels, and diving petrels. The crucial feature used to distinguish the northern giant petrel from the closely related southern giant petrel is the color of the bill tip: reddish-brown in the northern, and greenish in the southern. This characteristic is not always easy to spot at sea. Some southerns are all white, except for the odd dark feathers. This color phase does not occur in northerns, helping with identification. White phase southerns are more common at southerly breeding sites and are absent at the northerly ones.

The polar skua is able to fly the furthest south of all other Antarctic birds. It is light brown in color with a yellow neck. While flying, you can see a lighter band that crosses the lower surface of the wings. It has a dark beak, which is curved at the end. The feet are dark grey and almost black.

A wide bay located on the southwestern point of Wiencke Island, this site was used by whalers almost one century ago. There is an old British scientific base which is now a museum. Nowadays, it is not unusual to see minke and humpback whales cruising along the coast.

Upon arrival, you will find yourself on a small island dominated by a great amount of lichen growth and deep moss on the rocks, the only botanical species that you can find on the surface of Antarctica. As part of the scenery, you will see various birds, such as Wilson petrel, south and brown skuas, as well as one of the largest colonies of gentoo penguins.

This island is endowed with a unique beauty, due to its immense granite walls and the abundant snow that composes the scenery. It also has the largest and southernmost colony of Adelie and gentoo penguins, migratory species typical of Antarctica. On Petermann Island, you will be able to see a colony of Antarctic blue-eyed shag, a species much appreciated for its solemn stance and singular presence. During the summer, elephant seals come out in groups to enjoy the sun, basking on their sides atop the rocks of the island.
