Here's my entry for this week's Illustration Bandits theme "Mexican Animals".
It's an axolotl :) A walking fish! Or a salamander... Here's the official blurb from National Geographic:
"The Mexican axolotl (pronounced ACK-suh-LAH-tuhl) salamander has the rare trait of retaining its larval features throughout its adult life. This condition, called neoteny, means it keeps its tadpole-like dorsal fin, which runs almost the length of its body, and its feathery external gills, which protrude from the back of its wide head."
