Solomon island spiny monitor, Isabel monitor, Spiny-neck monitor
Varanus spinulosus, the Solomon Island spiny monitor, Isabel monitor, or spiny-neck monitor, is a species of monitor lizard. It is endemic to the Solomon Islands archipelago and is also known from Santa Isabel Island, San Jorge Island (Solomon Islands) and Bourgainville Island (Papua New Guinea).
This species is in many respects similar to the mangrove monitors of the V. indicus species complex, but has a number of unique morphological characteristics. It has a spiny scale texture as each of the small body scales are strongly keeled and conical in shape, which is a feature unique amongst all monitor lizards. It has 3-4 rows of bright yellow spots running across its back, and has relatively large eyes.
They feed on megapode eggs and on fish, often emerging from the bush. In the intertidal zone at low tide, it is possible that they would search for dead fish.
