Is There Any Poisonous Lizard In Maryland?

There are two lizard species that are considered poisonous in North America. These are the Gila monster and the Mexican beaded lizard. Both are large and thick bodies with short legs, living in the desert areas of Mexico, and the southwestern United States.

These do not make up any of the species you will come across in Maryland, but most reptiles do carry Salmonella, which you do need to be aware of.

Gila monster

Reptiles, if not all reptiles, carry salmonella bacteria in the intestinal tracks, shedding the bacteria in their feces. The reptiles don’t get sick from the bacteria, but it can cause serious illness in humans.

Salmonella can be spread easily from reptiles to humans when humans touch anything that the lizard may have been on or touched. In order for the bacteria to spread, it must be ingested.

It is often a problem when humans touch or handle a lizard and then later put their hands to their mouth. This is why it’s essential if you touch or handle any of the lizard species you find in Maryland, ensure you wash your hands thoroughly.

The seven types of lizards you can expect to come across in Maryland includes:

1. Broad-headed Skink

Male broad-headed skink

Scientific name: Plestiodon laticeps.

Common name: broad-headed skink, broadhead skink.

The broad-headed skink is the largest of the four skinks you will find in Maryland.

Juveniles also have bright blue tails, which fade as they age.

These skinks can be found in forest areas, where they spend a lot of their time in trees, basking in the sun, and catching prey.

They are not easy to spot, because they spend so much of their time high in the treetops.

Females are often seen in May to July when they come down to lay their eggs in decaying logs.

These skinks prefer wooded areas with access to water, such as creeks and springs.

If chased, they will drive underwater to hide under rocks and debris until the threat has passed.
