In a nice change of pace from news of species and habitat loss worldwide, meet the ten newly identified species scientists have selected as the best and most interesting of last year -- including a new snake and a new frog.

From Science Daily:

An amazing glow-in-the-dark cockroach, a harp-shaped carnivorous sponge and the smallest vertebrate on Earth are just three of the newly discovered top 10 species selected by the International Institute for Species Exploration at Arizona State University. A global committee of taxonomists -- scientists responsible for species exploration and classification -- announced its list of top 10 species from 2012 today, May 23.

No to the Mine! Snake
Sibon noalamina
Country: Panama

Snail-eating snake: A beautiful new species of snail-eating snake has been discovered in the highland rainforests of western Panama. The snake is nocturnal and hunts soft-bodied prey including earthworms and amphibian eggs, in addition to snails and slugs. This harmless snake defends itself by mimicking the alternating dark and light rings of venomous coral snakes. The species is found in the Serranía de Tabasará mountain range where ore mining is degrading and diminishing its habitat. The species name is derived from the Spanish phrase "No a la mina" or "No to the mine."

World's Smallest Vertebrate
Paedophryne amanuensis
Country: New Guinea

Tiny frog: Living vertebrates -- animals that have a backbone or spinal column -- range in size from this tiny new species of frog, as small as 7 millimeters, to the blue whale, measuring 25.8 meters. The new frog was discovered near Amau village in Papua, New Guinea. It captures the title of 'smallest living vertebrate' from a tiny Southeast Asian cyprinid fish that claimed the record in 2006. The adult frog size, determined by averaging the lengths of both males and females, is only 7.7 millimeters. With few exceptions, this and other ultra-small frogs are associated with moist leaf litter in tropical wet forests -- suggesting a unique ecological guild that could not exist under drier circumstances.

A just-published map of the world's most endangered species of mammals and amphibians shows that very little of the habitat critical to these species' survival is being protected.

From the BBC:

Amphibians are suffering a "terrifying" rate of extinction say the researchers, making them the most threatened vertebrates in the world. The Mexican salamander or axolotl is being threatened by expanding cities, pollution and invasive fish species which eat their young.

While many of the survival issues facing species highlighted on the map are extremely challenging, sometimes small changes can make a big difference.

(Zoological Society of London Director of Conservation Jonathan) Baillie highlights the example of a small worm like amphibian from Kenya called the Sagalla caecilian.

"It was just losing its habitat because the native trees were taken, so we've started a programme of replanting the native trees and 6,000 have been replanted and the areas where they have their strongholds are now being protected."

"That kind of simple action can ensure that those species can be there hopefully for hundred of years to come."
