Greek: toxon = crescent-shaped, ascaris = intestinal worm, leon = lion.

T. leonina occurs with a low host specificity in many canids and felids, reaches as females 10 cm or males 7 cm, and is characterized by very long and small cervical wings (Fig. 1). The development is direct without a wandering phase inside the host after oral uptake of larva-containing eggs.
