About Nucras tessellata (Smith, 1838)
Size and Body Shape
Nucras tessellata is a slender, whip-tailed lizard that reaches an overall length of approximately 25 cm. Around two-thirds of its total length is made up by its tail, which acts as a rudder during the lizard’s very rapid dashes.
Breeding Coloration
When in breeding coloration, the lizard shows strong black and white striping across its forequarters, while its hindquarters and tail turn a bright orange-brown.
Non-breeding Coloration
Outside of the breeding season, it retains striping along the full length of its body.
Activity Pattern and Preferred Prey
Nucras tessellata is most active during the morning and evening, when it hunts for its preferred prey: scorpions.
Supplementary Diet
It supplements its diet with spiders, grasshoppers, termites, and beetles, which it often digs out of these prey animals’ daytime retreats.
Habitat Range and Elevation
This lizard occurs across multiple habitat types, including savanna, karoo, and fynbos, at elevations ranging from 20 m (66 ft) to 1,500 m (4,921 ft) above sea level.
Microhabitat Preferences
While it is a secretive species, it is frequently found in dry river beds or sandy areas with scattered rocks.
