  • The bright yellowish-green patch on the cypress trunk consists of Chrysothrix candelaris, a species of crustose lichen. The greyish-white lichen is Cryptothecia evergladensis, a different type of crutose lichen. This tree with both species is growing in the Fakahatchee Strand of the Northwestern Everglades.

  • Quite a lucky find! While flipping over rocks searching for scorpions in northwestern Texas I chanced upon a (possibly brand new) desert subterranean termite colony. Normally found deep underground, under the rock I found the big queen termite, the king termite similar-looking but much smaller, and a number of worker termites. Hazarding a somewhat educated guess I'm going to say that these belong to the native Reticulitermes genus - a beneficial species that takes the role of fungus and algae in breaking down plant and wood material in the most arid of deserts where fungi and algae can't survive.

  • While there are many subspecies of the Florida tree snail in Southern Florida, and many found in the Caribbean (particularly in Cuba) I'm going to just focus on the species as a whole. These very interesting and often colorful snails which are found in smooth-barked trees have found a niche in their habitat feeding on algae and various fungi that that they find on their host trees. Unfortunately because of these beautiful shells, they are easily spotted in the wild and collected by shell-collecting people and are therefore considered "a species of special concern" by the Florida Fish and Wildlife Department. This one was found in on Key Largo in the Florida Keys.

  • This curious Pacific coast chiton is a nocturnal hunter that returns to the same rock after a night of hunting for algae along the intertidal zones of the Pacific Northwest. Often exposed during low tide, they are sometimes so fluorescent that they are known to glow in the dark and flash pink polka dots.

  • El Capitan in West Texas' Guadalupe Mountains (100 miles east of El Paso) is the world's premier example of an exposed fossil reef from the Permian Era, dated at about 260 million years old - much older than the golden age of dinosaurs. This whole part of Texas back in this time was once covered in a shallow sea that geologists call the Delaware Sea, in a time when all of Earth's continents were still joined into one supercontinent that we call Pangaea. The entire top of El Capitan is made of limestone formed from the fossilized remains of aquatic plant and animal remains such as corals, algae, shellfish and plankton, and now stands at just above 8000 feet above sea level. The base is formed by layer upon layer of sand laid down over millions of years, in the manner you would expect from the ocean floor resulting in a very typical sedimentary rock formation,  further eroded by millions of years of desert heat, rain, abrasion and wind.
