Athoracophorus bitentaculatus? Leaf-veined Slug. Compact, dormant posture. |

Athoracophorus bitentaculatus? Leaf-veined Slug. Active - moving at speed. |
This is no ordinary slug. With its leaf-vein pattern and distinctive body shape. It lacks an obvious mantle - the lump on the back which makes European slugs slug shaped. It belongs to a group called leaf-veined slugs - many are native to New Zealand, the rest come from neighbouring islands and Australia.
