Poisonous and Venomous Snakes

Four things, among many others, that I've harped on over the years are:
1.  Poisonous means toxic when consumed or absorbed.
2.  Venomous means toxic when injected via a sting or bite.
3.  It is rare that definitions can be given that are perfect and without exception.
4.  There are always exceptions to our understanding.

Red-Ear Turtle

Natural History Notes
by Bob Thomas

The most common water turtle in the Bayou Segnette area is the Red-earred Turtle, Trachemys scripta elegans. These are the little green turtles we used to buy at Walgreens, each with a red stripe behind the eye. As adults, they have shells that are about 10-12 inches long.

Atlantic Ridley Sea Turtle

Delta Journal
by Bob Thomas

Louisiana waters are host to at least occasional visits by all species of sea turtles that inhabit the Gulf of Mexico. Though our shores are a bit north of normal egg laying sites, occasional records exist for various species.

Mediterranean Gecko

Delta Journal
By Bob Thomas

During the spring and summer months, visitors to the Nature Center often ask "What are those little pink lizards on my screens at night?"

The answer: Mediterranean geckos (Hemidactylus turcicus), relatively recent immigrants from the Mediterranean Sea area that arrived here as stowaways on ships and in their cargo. First found in the United States in the Florida Keys in 1915, these lizards were abundant in Gentilly and the Vieux Carre by the late 1940's.
