Garter

Garters of the environnment

sf garter

San Francisco garter snake
Thamnophis sirtalis tetrataenia

There are an estimated 1000 to 2000 of this endangered subspecies. On this outing, we spotted four of them in two groups of two.

Etymology: the genus name is derived from the Greek roots thamnos for bush and ophio for snake.
"Sirtalis" is derived from the Latin for garter and apparently refers to the dorsal stripe(s).
The subspecies name is derived from the Greek roots tetra for four and taenia for ribbon.
The latter is also a genus of tapeworm including several human pathogens.

Olympus Tough - macro setting

This is a somewhat interesting comparison between a point and shoot and a DSLR.
A more precise test would control for focal point, lighting, and camera angle.
In any event, the Olympus Tough fared well.
