Scale-crested Pygmy-tyrant in Costa Rica.
Animals are a group of organisms that belong to the Animalia Kingdom. Animals first appeared during the Cambrian explosion some 542 million years ago.
The word "animal" is derived from the Latin word animalis, meaning "having breath".
Animals are heterotrophs, meaning they must consume other organisms as food. Most animals are also capable of moving spontaneously and independently. Animals are eukaryotic — meaning their cells have a nucleus in which genetic material is carried. Most animals are multicellular.
The best-known animals are vertebrates in the Chordata phylum (fish, amphibians, reptiles, birds, and mammals), but the vast majority of organisms in the Animal Kingdom are arthropods, which include insects, arachnids, crustaceans, and some other creatures. Vertebrates are the third largest group after arthropods and mollusks (like snails, squid, and clams).
Here are some pictures of animals. After the photos are recent news articles about animals.
Environmental news about animals
Gabon steps in to help protect elephants from ivory poaching at Central African Republic site
(05/18/2013) Gabon has agreed to help battle poaching in protected areas in the Central African Republic following an elephant massacre at a renowned World Heritage site, reports the Wildlife Conservation Society (WCS).
Crazy cat numbers: unusually high jaguar densities discovered in the Amazon rainforest
(05/16/2013) Jaguars (Panthera onca) are the biggest cat in the Americas and the only member of the Panthera genus in the New World; an animal most people recognize, the jaguar is also the third largest cat in the world with an intoxicatingly dangerous beauty. The feline ranges from the harsh deserts of southern Arizona to the lush rainforests of Central America, and from the Pantanal wetlands all the way down to northern Argentina. These mega-predators stalk prey quietly through the grasses of Venezuelan savannas, prowl the Atlantic forests of eastern Brazil, hunt along the river of the Amazon, and even venture into lower parts of the Andes.
Rhino populations in Sumatra, Borneo should be combined to save Sumatran rhino from extinction
(05/15/2013) A new study argues for treating endangered Sumatran populations in Borneo and Sumatra as 'a single conservation unit', lending academic support to a controversial proposal to move wild rhinos from Malaysia to Indonesia.
Photo: Stunning new pit-viper discovered in Honduras
(05/15/2013) A stunning new species of pit-viper has been discovered in the cloud forest of Honduras. The venomous snake is described in the journal ZooKeys.
Industrialized fishing has forced seabirds to change what they eat
(05/14/2013) The bleached bones of seabirds are telling us a new story about the far-reaching impacts of industrial fisheries on today's oceans. Looking at the isotopes of 250 bones from Hawaiian petrels (Pterodroma sandwichensis), scientists have been able to reconstruct the birds' diets over the last 3,000 years. They found an unmistakable shift from big prey to small prey around 100 years ago, just when large, modern fisheries started scooping up fish at never before seen rates. The dietary shift shows that modern fisheries upended predator and prey relationships even in the ocean ocean and have possibly played a role in the decline of some seabirds.
Five percent of ploughshare tortoise population perishes after botched smuggling attempt
(05/14/2013) In March, two people were caught attempting to smuggle 54 ploughshare tortoises (Astrochelys yniphora) into Thailand. Listed as Critically Endangered, the tortoises' wild population is down to approximately 400-500 animals in its native Madagascar, meaning the smugglers were attempting to move over 10 percent of the total population. Now, the Scientific American blog Extinction Countdown reports that nearly half of the smuggled tortoises have died of unknown causes.
Climate change to halve habitat for over 10,000 common species
(05/13/2013) Even as concentrations of carbon dioxide in the atmosphere hit 400 parts per million (ppm) for the first time in human history last week, a new study in Nature Climate Change warns that thousands of the world's common species will suffer grave habitat loss under climate change.
Why responsible tourism is the key to saving the mountain gorilla
(05/13/2013) The sunlight poured through the canopy, casting dappled shade over Makara, a large silverback mountain gorilla, as he cast his eyes around the forest clearing, checking on the members of his harem. A female gorilla reclined on a bank of dense vegetation of the most brilliant green, clutching her three day old infant close to her chest, and elsewhere, two juvenile gorillas played around a small tree, running rings around it until one crashed into the other and they rolled themselves into a roly-poly ball of jet black fluff that came to a halt a few meters in front of our delighted group.
For Mother's Day, pictures of mama animals with babies
(05/12/2013) One of the highlights of traveling to exotic planes is seeing mother animals with their babies so here is a collection of a some pictures I've taken over the years. They range from amphibians in Panama to orangutans in Borneo. I hope you enjoy. Happy Mother's Day!
Scientists discover that marine animals disperse seagrass
(05/09/2013) Lesser known than coral reefs, marine seagrass ecosystems are rich in biodiversity and are powerhouses when it comes to sequestering carbon dioxide. Yet, much remains unknown about the ecology of seagrass beds, including detailed information on how seagrass spread their seeds and colonize new area. Now a recent study in Marine Ecology Progress Series documents that several species of marine animal are key to dispersing seagrass, overturning the assumption that seagrass was largely dispersed by abiotic methods (such as wind and waves).
