Whales are the earth's largest creatures, yet they are incredibly hard to study in the open ocean. For decades scientists have used boats, aircraft and even high cliffs to conduct visual surveys and gather data on whale and dolphin populations. Today, these live surveys form the basis of our knowledge of these marine mammals"”what species live where in the world, which ones tend to live together and how abundantly they are represented. Now, recent work by paleobiologist Nick Pyenson of...

Dolphins and porpoises use echolocation for hunting and orientation. By sending out high-frequency sound, known as ultrasound, dolphins can use the echoes to determine what type of object the sound beam has hit. Researchers from Sweden and the US have now discovered that dolphins can generate two sound beam projections simultaneously. "The beam projections have different frequencies and can be sent in different directions. The advantage is probably that the dolphin can locate the object more...

Bottlenose dolphins* and beluga whales**, two marine species at or near the top of their respective food webs, accumulate more chemical pollutants in their bodies when they live and feed in waters near urbanized areas, according to scientists working at the Hollings Marine Laboratory (HML), a government-university collaboration in Charleston, S.C. In papers recently published online by the journal Environmental Science & Technology, one research team looked at the levels of persistent...

A study published in the Journal of Experimental Biology shows that seals can detect the size and shape of objects by sensing differences in the trail of disturbance they make in the water and use this ability to identify the best fish, BBC News is reporting. Dr. Wolf Hanke and scientists from the Marine Science Center at the University of Rostock, Germany, first showed how sensitive seals' whiskers were last year when they reported that a trained seal named Henry was able to sense an...

In a recent study to be published on April 27, 2011, in the peer-reviewed open-access journal PLoS ONE, Dr. Elliott Hazen and colleagues found that oceanographic and prey measurements can be used to identify beaked whale foraging habitat. The research team from Duke University, Woods Hole, and the Naval Undersea Warfare Center listened for foraging beaked whales and measured ocean features and distributions of prey off the east coast of Andross Island in the Bahamas. Their manuscript provides...

Scientists are baffled by the continuing numbers of dead baby bottlenose dolphins washing up on the shore of the Gulf of Mexico. 406 dolphins were found either stranded or dead between February 2010 and April 2011, prompting the National Oceanic and Atmospheric Administration (NOAA) to designate the deaths as an "unusual mortality event" (UME). The agency defines such events as a stranding incident that is unexpected or involves great losses of any marine mammal population. Blair Mase, the...

Study by Wildlife Conservation Society, AMNH, on dolphins finds invisible oceanographic factors that keep populations separateConservationists from the Wildlife Conservation Society, the American Museum of Natural History, and other conservation and research groups have discovered that groups of dolphins in the western Indian Ocean do not mix freely with one another. In fact, dolphin populations are kept separate by currents and other unseen factors.Specifically, the researchers have found...

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,...
