    When you think about the illegal trade in wildlife, large, charismatic species usually come to mind, like elephants or tigers, or perhaps the weirdly armored pangolin, the world’s most trafficked animal, valued for its meat and scales.

    Putting up a live Christmas tree can be a lot of work. You have to make sure that the tree has plenty of water, sometimes having to crawl beneath the branches while trying not to dislodge any of the breakable ornaments.

    Since its discovery in the 1990s, a contagious cancer called devil facial tumor disease has wiped out 85 percent of the Tasmanian devils on the Australian island of Tasmania. The animals have yet to completely disappear from any one area of the island, but in some places, as many as 95 percent of the devils are now gone.

    As much as I love my own kitty, I have to admit that the domestic cat (Felis sylvestris catus) has become quite the menace around the world. The cat’s power to be a bird-killing machine often gets the most attention, but its ability to breed with wild members of its species also poses a big threat. In some places, such as Scotland, the local wildcat population has been largely replaced by genetically distinct hybrids.

    It may not be polite to eavesdrop, but sometimes, listening in on others’ conversations can provide valuable information. And in this way, humans are like most other species in the animal world, where eavesdropping is a common way of gathering information about potential dangers.

    Last weekend I watched Jurassic Park for the first time in years. Still awed by the seemingly realistic, long-extinct animals, I started wondering: What would happen if they escaped the remote Pacific island where they had been created and made it to land? The only dino in the movie series to make it to a continent was a Tyrannosaurus rex in The Lost World: Jurassic Park. And it had been shipped to San Diego by stupid humans.

    Other than the tiny population of panthers in Florida, cougars haven’t lived in the eastern United States for at least 70 years. There are occasional visitors from the west or south, but the eastern cougar (Felis concolor couguar) is probably extinct. For that reason, the U.S. Fish and Wildlife Service proposed removing it from the endangered species list earlier this summer.

    The prospect of resurrecting mammoths is back in the news after Harvard geneticist George Church announced last month that he may be only two years away from creating a mammoth-elephant hybrid fetus. That’s still a long way from a living mammoth — let alone herds of the animals — and scientists are skeptical that Church will be successful with even a hybrid fetus. The scientific hurdles that will have to be overcome are huge.

    There’s a good reason why so many people want to go on an African safari - savannas in Kenya and other countries are home to plenty of large, photogenic animals, including elephants, giraffes and lions. Who wouldn’t want to see those creatures up close?

    As carbon dioxide levels in the atmosphere rise, the world’s oceans are absorbing some of the gas and slowly becoming more acidic. That acidification impedes the chemical reaction that many marine species use to make calcium carbonate shells and skeletons. Fish were once thought to be immune to the drop in pH, but a growing amount of evidence show that these species, too, are affected. Now comes evidence that acidification might be a problem for freshwater fish as well.

    f you spot an ocean sunfish (Mola mola) near the surface of the water, you might be amazed by its size. These are, after all, the biggest of all the teleost fish (the group of ray-finned fishes that includes many of the species we like to eat), and they can grow as large as 1,000 kilograms. You may also think the fish are nothing but lazy sunbathers.

    There’s a fabulously named drunken monkey hypothesis that posits that humans’ love of alcohol comes from our primate ancestors. Those primates, the theory goes, got an evolutionary advantage from being able to eat lots of fermenting fruit and the ethanol that forms in the process.

    For millions of Americans, Thanksgiving is an excuse to gorge on turkey, stuffing and pumpkin pie, despite the warnings that overeating, even for a day, can be incredibly unhealthy. But for a Burmese python, enormous meals are the norm. These huge snakes - they can reach up to 6.7 meters in length - may go weeks or months without eating, so they have to make their meals count. And they have many adaptations that let them consume quantities of food that would be impossible for a human to take in.

    The neck of a giraffe isn’t all that different from any other mammal’s. There are seven neck vertebrae, like those of humans, but they are much bigger.
