Mini Monster Mayhem is tomorrow! And while it’s all about the invertebrates, we couldn’t help but showcase this recent find.
The red eft! Always a welcome sight here in the watershed.
And with quite the lifestyle!
The red eft is actually the juvenile, terrestrial stage of the eastern newt (Notophthalmus viridescens). Uniquely enough, this eft began its life in a nearby pond, eventually absorbing its gills. Now, it will remain terrestrial for the next two or three years before returning to another nearby waterway where it could live an additional ten years as an aquatic adult.
And its red color is exactly what you think! It's a variation of aposematism - meaning "stay away" to any would-be predator. The efts' tissue is saturated with tetrodotoxin, the same neurotoxin found in pufferfish and the blue-ringed octopus. While perfectly safe to handle, like a pufferfish, they are best left alone based on their fragile existence. The danger only exists if ingested.
Like many other species in the watershed, the red eft is considered a sensitive species. They are an indicator of ecosystem health and likewise serve an enormous purpose by consuming large quantities of mosquito larvae and other insects compared to their body size.
They can also regenerate limbs!
This all sounds pretty mini monster to us!
