Jamaican giant galliwasp, the lost lizard
The Jamaican giant galliwasp, a lizard up to 60 cm long, was last collected around 1840 in western Jamaica. Jamaicans feared galliwasps as venomous, which they are not.

The account
Folklore said a person bitten by a galliwasp would die unless they reached water before the lizard did. Rumoured sightings in the Westmoreland swamps have kept it a 'lost' animal, but it is thought extinct, probably killed off by introduced mongooses.
The researched reading
A real lizard, probably wiped out by introduced predators, that lives on in folklore. Rumoured sightings are most likely other lizards.
| Explanation | Weight | Why |
|---|---|---|
| Something known, misidentified | 35% | Jamaicans call several lizards “galliwasp”. Recent reports of a large one are most likely smaller Celestus species or other lizards seen briefly. |
| A cultural story | 35% | The galliwasp is a feared animal of Jamaican folklore, with stories of its deadly bite and of the race to water. The name lives on in stories after the animal has gone. |
| An unknown or out-of-place animal | 15% | Last collected around 1840 and listed as possibly extinct; about 30 museum specimens prove it existed. Surveys of the Black River Morass have not been exhaustive, so survival is unlikely but not excluded. |
| Perception, memory or mind | 10% | Fear and expectation make brief glimpses in the swamp seem bigger. |
| A hoax or fabrication | 3% | No known fabricated evidence. |
| Genuinely anomalous | 2% | A surviving lizard would be zoology, not an anomaly. |
Official position: Listed as Critically Endangered (possibly extinct) by the IUCN; no confirmed record since the mid-19th century.
