This is a photo of a blue poison dart frog. Frogs are one example of amphibians. Amphibians are cold-blooded vertebrates usually born as aquatic, goll-breathing organisms preceding the later terrestrial, lung-breathing adult stage. This includes frogs, toads, newts, and salamanders.
This is a picture of a common daylily which shows the anther and filament of a stamen. This is where the pollen of a flower is stored and produced. The anther holds the pollen while the filament, a long stem-like structure, holds the anther up so pollinators can reach it. The anther can either be placed at the end of the filament (as pictured) or towards the center.
