The emblem of the Tasmanian state, the Tasmanian devil (Sarcophilus harrisii), is the largest carnivorous marsupial in the world. It is found on the island of Tasmania, Australia. Fossil evidence suggests that it once occupied the entire Australian mainland some 3,000 years ago. “Devil” was attributed to these animals for their appearance and otherworldly/unearthly screeches at night. These sounds are reflective of fear rather than aggression, however.
About the size of the dog, these red-eared devilish creatures can devour medium to large-sized mammals as well as invertebrates with their wide jaws and sharp teeth. However, they serve their ecological role more like scavengers than predators. They feed on carcasses. The nocturnal animal lives in solitary, changing dens every third day of the week, and can travel about 6 miles at night.
Axolotls could help in regeneration!
You might be reading this headline for the first time, but it is true. When it comes to regeneration, Urodele Amphibian, better known as Axolotls (Ambystoma mexicanum) are the champions. They don’t form scars on wounds, instead they regrow their lost parts. Scientists are hopeful for human limb regeneration based on this knowledge.
Like their striking regeneration ability, they possess distinguished larval features as well. These include a flat body, dorsal fins, three pairs of protruding feathery gills, and a slight grin. They can grow up to one foot. These long-living Mexican salamanders live up to 15 years.
Unlike other salamanders that metamorphose into terrestrial amphibians, the fleshy-pink Axolotls defy the biological laws of metamorphosis. They hold onto their juvenile features throughout their adulthood, so they are known as neonates.
