The marine otter (Lontra feline) is a member of the weasel family, and can be found in South America. It prefers a habitat in rocky coastal areas, with a range that includes the entire coastline of Chile and extends to southern Peru and Argentina. It has been found on the Falkland Islands, but individuals here do not represent a constant population. Unlike other species of otter, the marine otter chooses to live near waters with high winds and swells. It may use caves and crevices as dens,...
The crabeater seal (Lobodon carcinophagus) is a true seal that can be found around the whole of Antarctica. Its range also includes small areas in South America, New Zealand, Africa, and Australia. It resides on the pack ice zone for the entire year, even as it shifts seasonally, and prefers to stay in the continental shelf area in water with a depth of less than 1,968 feet. Because the populations are so wide spread and are sufficiently mixed, there have been no subspecies found. Because...
The Mediterranean monk seal (Monachus monachus) is a rare pinniped, or “fin-footed mammal” that can be found in areas of the Mediterranean Sea, as well as in the Atlantic waters of the Tropic of Cancer. Not much is known about the chosen land habitats of this seal, but until the 20th century, it could be seen relaxing or pup rearing on open beaches. It now dwells in underwater caves and caverns in order to escape human actions including tourism and expansion. The Mediterranean monk...
Profilicollis is a genus of acanthocephalan parasites that are found in crustaceans and shorebirds. Profilicollis parasites use decapod crustaceans as intermediate hosts and species of shorebirds as definitive hosts. The parasite first develops in mole crabs of North and South America. After it infects a mole crab, it becomes dormant until the crab is eaten by a suitable bird, such as a Surf scoter or Herring Gull. Once the parasite has passed through the stomach of the bird, it develops...
The Chinese white dolphin, otherwise known as the Indo-Pacific humpback dolphin, is a species of humpback dolphin that can be found in the waters of Southeast Asia. When breeding, they will travel to the waters around South Africa to Australia. There are currently two recognized subspecies of the Chinese white dolphin. The coloring of the Chinese white dolphin can vary due to age and location. When born, calves are actually black, but will change to grey, then pink with white spotting,...
