I really love fishing! I can't think of a more relaxing time than sitting by the lake, or a more exciting time than going deep sea fishing. Therefore, I find animals that have come up with unique ways of catching fish pretty interesting. Take for example the humpback whales that we talked about in…
Researchers have discovered that dolphins might be able to learn a new language! Four captive bottlenose dolphins in Port-Saint-Pere, France have repeatedly heard recorded whale sounds during their various performances at the aquatic park. When researchers recorded the dolphins talking in their…
A reader asked if there was an herb equivalent to catnip for dogs. In my search for the answer to that question, I came across many articles claiming that although some dogs will actually respond to catnip, aniseed is to dogs what catnip is to cats. Foxhounds will reportedly follow the scent of…
Just in case you have not yet had a chance to see this video of a murmuration (a flock of starlings) showing thousands of the birds and their impressive ability to coordinate flight, here it is. I can see why it went viral, it really is a must-see:

If you are a blue-footed booby, the answer is yes. Female blue-footed boobies find males with bright-blue feet pretty sexy. The problem is repeated mating comes with diminished foot color and attractiveness as the males get older. What is a male with dull feet to do? Apparently the solution is easy…
I just finished reading an interesting article from The Scientist on what makes catnip so addicting to our feline friends. In our house, we refer to it as "kitty pot" because our cat just can't seem to get enough of the stuff. One sniff and he is rubbing all over the plant and then does a few laps…
Scientists exploring newly discovered deep-sea vents in the Antarctic have also discovered new species of hairy-chested yeti crabs (the "hair" being from bacteria), anemones, and predatory seven-armed sea stars. Many of these animals have never been seen before at hydrothermal vents explored in…
There is a new suspect thought to contribute to the demise of honeybee (Apis mellifera) colonies worldwide, termed colony collapse disorder (CCD).
Until now, scientists have identified a host of potential culprits including pesticides that might weaken their immune systems, pathogens, parasites,…
Dr. Nicholas Grahame and colleagues at Indiana University-Purdue University in Indianapolis have selectively bred mice that prefer drinking alcohol and apparently binge drink. Until now, other mice would choose water over alcohol. These inebriated mice are the first model of severe human…
This is an exciting day for a comparative physiologist! I just received word from a reader that the top 10 newly discovered species of 2011 have been chosen. This is an annual "contest" put on by the International Institute for Species Exploration at Arizona State University along with an…
See the amazing symbiotic relationship that has evolved between jellyfish and algae. This relationship began 12,000 years ago when ocean levels were higher as a result of melting glaciers. With the higher ocean levels, creatures like the golden jellyfish trickled into an island lake. As the ocean…
In the search for energy efficient animals, I came across this neat little bug, the Oriental hornet (Vespa orientalis) that can apparently derive energy from the sun. These bugs will actually work their hardest when the sun is at its peak, which is in contrast to similar species that work hardest…
More than 200 new species have been discovered since last year in Greater Mekong region. My new favorite is the snub-nosed monkey that looks like Elvis.
A researcher studying the evolution of laughter has observed that things that make us laugh, like tickling our feet, also make our ape relatives giggle like children:
To hear the gorilla better, watch this more recent video:

Researchers have discovered that the reason chimpanzees eat certain foods may have nothing to do with having a sophisticated palate, but rather, the animals appear to be self-medicating. I suppose if you were a chimpanzee it would be difficult to find a doctor to treat…
The Smithsonian National Zoo needs your help naming this young giant Pacific octopus:

The deadline for submitting entries is December 12th at 5pm. The caveat: to suggest a name, you must be a child between the ages of 5 and 15 years. If you (…
Was anyone able to see the special on Nova "The Incredible Journey of the Butterflies" that aired yesterday? Talk about long-distance migration! Every year, over 100 million newly hatched monarch butterflies travel from southern Canada and the northeastern United States ~2000 miles on a 2 month…
In a global effort to understand whale communication, researchers have created a website asking people from around the world to match songs recorded from pilot and killer whales. The songs were recorded using suction-cup sensors that not only record the tagged animal's songs, but also those of…
Good news for those interested in discovering new species. Researchers have used taxonomic data to estimate the total number of species in a taxonomic group. Using this information, they have determined that there are approximately 8.7 million species of eukaryotes around the world. Of those, about…
In our continuing coverage of just how neat these animals are, check out this video showing an octopus taking a stroll on the beach at the Fitzgerald Marine Reserve in Moss Beach, California.

For those unable to view the previous video explaining the evolution of turkeys from dinosaurs, or would rather see a synopsis, here is a short YouTube clip:
Happy Thanksgiving!
Here is a neat special from National Geographic showing the evolution of turkeys from dinosaurs:
Happy Thanksgiving everyone!

A new species of walking epaulette sharks (Hemiscyillum freycineti) has been discovered off the coast of Indonesia. These sharks actually walk using their pectoral fins. Take time out for a dive alongside this shark and see some other amazing ocean wildlife in this diver's video:

Hans Jusseit, a tuna fisherman, has designed a shield to protect the bait on fish hooks (image above). These are not just any fish hooks. These hooks are for catching large fish, like tuna, using longlines like the one shown in the picture below.

The tammar wallaby is the first Australian marsupial to have its genome sequenced. Researchers were surprised to find out that many of the wallaby genes are similar to those found in humans. Because baby wallabies (aka: joey) develop in a…
The last stop on our trail of physiology this Fall is Arizona. The Arizona Physiological Society held their annual meeting on the Medical Campus of the University of Arizona in Tucson on November 11-12.
The meeting opened with a special session for future (and current) physiologists interested…
These are just a few of my favorite recent discoveries.
A new species of "albino" trapdoor spiders has been discovered in Australia. The aptly named spiders build trapdoors hinged with silk leading into their burrows. When prey walk by, the spiders sense the vibrations and spring out for the…

Well, the paternity tests are in and the results are not looking very good. It turns out that arctic foxes are not monogamous after all. When resources are abundant, populations of breeding pairs expand and the female arctic foxes mate with other males, cheating on…

Until now, scientists thought that the spotted horses depicted in ancient cave paintings, like the image above, were works of imagination and that this leopard…
Dr. Jon Costanzo, Senior Research Scholar and Adjunct Professor in the Department of Zoology at Miami University in Oxford, OH was invited to tell us about his amazing research on wood frogs; animals that can actually survive freezing! Here is his post:
