Common Name: Northern Spectacled Salamander
Scientific Name: Salamandrina perspicillata
Family: Salamandridae
Location: Italy
Size: 1.3 inches for Snout to Vent, 3.3 inches for Total Length

The Northern and Southern Spectacled Salamander used to be only one species until they were split in 2005 due to genetics. The Northern Spectacled Salamander lives in the northern and central parts of Italy while the Southern Spectacled Salamander lives in the southern part of Italy.

The Northern Spectacled Salamander is a terrestrial species of salamander that is active during the night. They can live up to 15 years. When a predator approaches the salamander, they curl into a ring to show off their red bellies. This shows off that they are not good to eat.

Harlequin Toads (Atelopus)

 

 

Family: Bufonidae
Number of Species: 97
Location: Central and South America

The members of the genus Atelopus are commonly referred to as the Harlequin Toads or Stubfoot Toads. There are many members of the genus but the majority of them are endangered of becoming extinct. Many species in the genus haven’t been seen in decades. The main culprit of their status is Chytrid Fungus, a deadly fungal pathogen that affects amphibians. Also habitat lose, pollution, and invasive species are also not helping these toads. These toads are often brightly colored and beautiful so it would be shame if they went extinct.

Frog of the Week

Emerald Glass Frog (Espadarana prosoblepon)

leastconcern
Common Name: Emerald Glass Frog, Nicaragua Giant Glassfrog
Scientific Name: Espadarana prosoblepon
Family: Glass Frog Family – Centrolenidae
Location: Colombia, Costa Rica, Ecuador, Nicaragua, and Panama
Size: 1.2 inches or 31 mm for females, 1.1 inches or 28 mm for males

The Emerald Glass Frog is a beautiful frog from Central and South America. Like other glass frogs, the Emerald Glass Frogs skin is see through, hence the name and they live their lives in the trees. The Emerald Glass Frog even mates in the trees.

Male Emerald Glass Frogs claim territory over hanging trees during the mating season which is from May to November (during the rainy season).  If another male enters the territory, a fight may break out. These fights can take over 30 minutes long and last until one frog falls from the tree or gives up.

When the female enters the territory, the male jumps on her back and they start to reproduce. They lay their eggs on leaves or rocks overhanging streams and then they leave. The eggs hatch a week or so later and the tadpoles then fall into the stream.

Rough Skinned Newt (Taricha granulosa)

leastconcern
Common Name: Rough Skinned Newt
Scientific Name: Taricha granulosa
Family: Salamandridae
Location: Canada and the United States
US Location: Alaska, California, Idaho, Montana, Oregon, Washington
Max Size: 8.6 inches / 22 cm entire length. 3.4 inches / 8.7 inches for Snout to Vent

The Rough Skinned Newt is the most poisonous newt in North America. Its poison is used to scare off predators and is even harmful to humans. When attacked, the Rough Skinned Newt moves into the unken reflex position, where the newt raises its head and tail up so the predator can see the bright coloration that warns that the species is poisonous. Other amphibians also perform the unken reflex.

Every year, the newts migrate to their breeding sites. Mating happens from March to May, depending on where the newts live. Males try to court females through amplexus and rubbing their head on the female’s head. Fertilization for the species is internal. The male deposits sperm on a surface and the female picks it up. The female then lays eggs shortly after.
