Ginger, Oakland Zoo's river otter, gave birth to a litter of three baby otters on February 18, 2012. They each weighed approximately 150 grams at birth. Currently, the pups are nursing, starting to open their eyes and are growing each day. In a few weeks, they will begin eating fish and meat. Keepers also say the babies are very vocal, especially the female. The baby otters will not go out on exhibit until May as they first need to learn how to swim (it´s not instinctual) and need to be...

In the dark world of the underwater ocean, whales need to locate their prey accurately and quickly. In low-vision conditions whales use echolocation to find fish swimming nearby, and now it has been discovered that they can focus their acoustical “vision” to accurately located slightly differing objects. For this study, Laura Kloepper from the University of Hawaii and her her PhD supervisor, Paul Nachtigall, utilized the help of Kina the False Killer Whale, a species related to...

False killer whales focus echolocation clicks Hunting in the ocean's murky depths, vision is of little use, so toothed whales and dolphins (odontocetes) rely on echolocation to locate tasty morsels with incredible precision. Laura Kloepper from the University of Hawaii, USA, explains that odontocetes produce their distinctive echolocation clicks in nasal structures in the forehead and broadcast them through a fat-filled acoustic lens, called the melon. 'Studies by other people showed...

Unique Whistles Allow Dolphins To Greet Each Other
2012-03-01 05:45:52

Marine biologists have discovered that bottlenose dolphins use whistles to greet other members of their species. The researchers in Scotland said they made recordings of dolphins swimming in St. Andrews Bay in the summers of 2003 and 2004 by using hydrophones. They said when the group of dolphins met up, they swapped whistles that outwardly sounded the same. "The whistle exchange is more of a greeting ceremony that communicates a friendly intention and is perhaps not needed to...

New Protected Areas For Dolphins Declared
2012-02-17 04:17:55

New hope for threatened freshwater dolphins in Asia The Government of Bangladesh recently declared three new wildlife sanctuaries for endangered freshwater dolphins in the world's largest mangrove ecosystem — the Sundarbans, according to the Wildlife Conservation Society (WCS) whose conservation work helped pinpoint the locations of the protected areas. The sanctuaries, which were officially declared on January 29, will protect the last two remaining species of freshwater dolphins...

Elephant Seals Forced To Dive Deeper Due To Ocean Warming
2012-02-10 04:47:00

Global warming is having an effect on the dive behavior and search for food of southern elephant seals. Researchers from the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association cooperating in a joint study with biologists and oceanographers from the Universities of Pretoria and Cape Town have discovered that the seals dive deeper for food when in warmer water. The scientists attribute this behavior to the migration of prey to greater depths and now wish to...

Ecologists Capture Sounds From The Deep Sea
2012-01-30 13:12:53

Ecologists have captured 12 distinct sounds from deep sea fish at a depth of 2,237 feet below the North Atlantic. The team was exploring the idea that many fish make sounds to communicate with each other, particularly those that live in the deep part of the ocean. The University of Massachusetts scientists used hydrophones deployed by fisherman during normal fishing operations.  They obtained 24-hours of recording in Welkders Canyon south of Georges Bank. Some of the more...

Marine Otter, Lontra feline
2012-12-28 15:09:41

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,...

Crabeater Seal, Lobodon carcinophagus
2012-06-26 14:40:11

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...

Mediterranean Monk Seal, Monachus monachus
2012-06-23 10:50:34

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
2014-01-05 00:00:00

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...

Chinese White Dolphin, Sousa chinensis chinensis (known as rare pink dolphins)
2012-05-25 11:45:30

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,...
