Hello! My name is Sal, short for Salvador. I am a brown salamander for The Creek. Coming to you live!
Step 1: Overproduction of Offspring
We overproduce because not all of our young will survive. Some of them will get eaten by predators or get squished by a rock. Salamanders can lay up to 450 eggs at a time!
Step 2: Genetic Variation
Salamanders can come in all colors. Some have smooth, brightly colored skin, while others are more spiny and neutral.
Most of the salamander population are around six inches long. However, the Japanese giant salamander can grow up to six feet long.
Lots of salamanders have glands that produce a poisonous or gross-tasting substance.
Step 3: Selection
Salamanders' bright colors warn potential predators of their poison. Other animals will leave them alone because they look inedible. Here's Sulfur Sam with the latest on the desert.
Step 4: Adaptation
Thanks Sal! Salamanders almost universally live near a source of water. However, where I live, there's only water for a limited amount of time every year. During the rainy season I bulk up and find a real cutie to mate with. When the thunder stops rolling, I roll into bed and into my burrow again for the next 9 months. Back to you, Sal.
This has been The Creek! Thanks for watching, and tune in next time for turtles.
