New Zealand Seashore

DSC_4726 Grey side-gilled sea slug (Pleurobranchaea maculata) juvenile. Until 2009, it was not known that this sea slug contains tetrodotoxin (TTX) – a toxic substance that killed several dogs on an Auckland beach, presumably after they ate the slugs. This common and rather nondescript sea slug, is now considered our most toxic creature. Goat Island Marine Reseve, Leigh *
