Salamanders are, globally, one of the most successful amphibian groups on land. There are nearly 800 species. They live under rocks, inside rotting logs, in mountain streams, and in underground caves. They hunt insects, worms, and slugs. They are moist-skinned, secretive, and ancient – fossils date back 160 million years. And they are everywhere. Except here. A ghost that never arrived. Two words explain their absence: deep time. When New Zealand split from Gondwana around 80 million years ago, it carried away a cargo of frogs (our native leiopelmatids – the primitive frogs) and lizards. But salamanders? They hadn't yet diversified into the groups that would colonise the southern landmasses. The ancestors of modern salamanders were still mostly in the northern hemisphere. By the time salamanders became global travellers, New Zealand was already an island, drifting alone, unreachable across a cold, deep ocean. What filled the gap? Skinks and geckos. In most of the world, lizards and salamanders split the ground-hunting niche – lizards in the sun, salamanders in the damp. But in New Zealand, with no salamanders to compete with, our native skinks and geckos moved into the wetter, darker, cooler spaces. They hunt at night. They hide under logs. They eat the same invertebrates that a salamander would eat. They are, in a very real sense, lizards trying to be salamanders. Evolution is not a ladder. It is a game of musical chairs. When a niche is empty – no salamanders eating slugs in the damp forest – something else will eventually slide over and take the seat. In New Zealand, that something was a lizard with a taste for the dark. The salamander is a ghost that never arrived. The damp forest is dark. A skink hunts under a log, eating slugs, doing the job of a salamander. It does not know it is filling a gap. It does not know it is a lizard trying to be a salamander. It just wants to eat a slug. The absence shaped the forests of New Zealand just as surely as any presence ever could. The salamander is proof by not being here.
