Why Lizards Matter
Lizards play important roles in ecosystems: they eat insects and other small animals, helping control pest populations and supporting biodiversity. They’re fascinating, varied, and often overlooked.
Quick ecosystem role
By preying on insects and small invertebrates, lizards help keep populations balanced and reduce pressure on crops — a natural form of pest control.
Some neat reptiles
-
Iguana
Marine iguanas in the Galápagos forage in the ocean and sneeze excess salt through special glands. Marine iguanas are the only lizards that regularly swim and feed in the sea. They can hold their breath and graze on algae underwater.

Snakes (example)
Some snakes (pit vipers, boas) have heat-sensing pits that detect infrared. Certain snakes can detect infrared radiation with specialized pits, allowing them to sense warm prey in darkness.

Great Plains Skink

-
Western Skink
Juvenile western skinks have bright blue tails that fade with age. Young western skinks have electric-blue tails that distract predators; the tail can autotomize (detach) to allow escape.
-
Rubber Boa
Many rubber boas show healed scars on the tail used as a decoy head. Rubber boas often present a tail that looks like a head to confuse attackers; the tail is commonly scarred from this defense tactic.
-
Island Glass Lizard
Glass lizards can break tails into multiple wriggling pieces to confuse predators. Unlike snakes, glass lizards have eyelids and ear openings. Their tails can fracture into sections that keep moving and distract threats.
