Iberian worm lizard; European worm lizard
A species of amphisbaenian reptile (Blanus cinereus) found in the Iberian Peninsula. The Japanese name literally means 'Balkan worm lizard', but it refers to the European worm lizard.
The Iberian worm lizard is a type of lizard that looks like an earthworm.
Standard katakana spelling; the word is usually written in kana.
Kanji spelling using rare characters; almost never used in practice.
From バルカン (Balkan) + ミミズトカゲ (worm lizard), though the species is native to the Iberian Peninsula, not the Balkans. The exact reason for the 'Balkan' designation is uncertain.
