Aranaccio

Aranaccios  (Anura Aranccios) are a species of magical amphibians.

Physical Description
Aranaccios are a rare frog-like species whose blood consists of perpetual ice. Their skin has a spiky appearence due to the icicles which form on their body.

Behaviour
It is believed that they luminesce various turquoise colours in order to communicate with each other. Aranccios live in mainly in Siberia. At night they hunt insects in trees and they sleep at the bottom of frozen ponds during the day.

Magical Abilities
Arnaccios apparently have no other magical abilities than their icy constitution and their ability to glow for communication. However, their ice-like eggs are speculated to have some use in potions, though the rather secretive Siberian wizards refuse to divulge their secrets.

Etymology
It is unclear exactly where the name "Aranaccio" originates from, although some wizarding linguists speculate it may be a combination of the Latin for tree, "arbor", and the Italian for frog and ice, "rana" and "ghiaccio" respectively.

History
Very little is known about Arnaccio's history; whether they are naturally-occurring animals or the creation of some ancient wizard is heavily debated. Their existence has been attested in Siberia since the 9th century.

British Ministry of Magic Classification
Aranaccios are classified as Beasts. Their threat level, pending more investigation, is XX.
