  • On August 21, 2017 the path of the first solar eclipses over the Unites States in 38 years traversed approximately 2,500 miles of the country from Newport, Oregon to McClellanville, South Carolina.  Just outside Shoshoni, Wyoming, the path passed over Boysen Reservoir.  At this location, totality lasted 2 minutes and 22 seconds, being at its maximum about 11:40 am.  With the moon blocking the solar disk during totality, red flares called solar prominences become visible at the edge of the dark disk.  The red-glowing looped material is plasma, a hot gas composed of electrically charged hydrogen and helium. These prominences look small in relation to the size of the sun, but typically extend over many thousands of kilometers with the largest on record being estimated at over 800,000 kilometres (500,000 miles).  A prominence forms over timescales of about a day and may persist for several weeks or months.<br />
<br />
During the total solar eclipse, the sun’s outer atmosphere called the corona becomes visible as it extends millions of miles into space.  The corona consists of extremely hot ionized gases which exceed 1 million degrees Kelvin – 150- to 450-times hotter than the surface of the sun.  Being over 1 million million times less dense and much hotter than the sun’s surface and the solar prominences, the corona actually produces about one-millionth as much visible light, thus becoming visible from earth typically only during a total solar eclipse. The sun’s magnetic fields bend the corona into its remarkable shapes.<br />
<br />
In this image, 10 different photographic exposures of the solar eclipse were composited to show the eclipsing moon, solar prominences and the corona.  The image was then manipulated by a process called embossing where each pixel is replaced either by a highlight or a shadow, depending on light/dark boundaries on the original image.  The final image represents the rate of color change at each location of the original. This approach accentuates the pattern

  • This Banded Butterflyfish (Chaetodon striatus) is passing through a Slimy Sea Plume  (Pseudopterygorgia Americana) at 52 feet below the surface of the Riviera Maya in the Gulf of Mexico.   The banded butterflyfish is found in tropical waters of the western Atlantic Ocean from Brazil to Bermuda. The name is derived from the dark vertical bands on the fish's body and the vertical black bar through the eye.  These markings disrupt the outline of the body and act as an efficient antipredator adaptation.  The banded butterflyfish diet consists mainly of small invertebrates, crustaceans, coral polyps, polychaete worms and various eggs. Sometimes they will even act as a cleaning fish and remove external parasites from surgeon fish, grunts and parrot fish.

  • The Coney (Cephalopholis fulva) is found from Bermuda and South Carolina to southern Brazil, including the Gulf of Mexico and Atol das Rocas.  They are common in the Caribbean and less common in southern Florida and the Bahamas. <br />
<br />
The Coney weighs about a pound (0.5 kg), although occasionally it can weigh as much as 3 pounds (1.4 kg). Their average length is 6 to 10 inches (15-25 cm), with a maximum length of 16 inches (41 cm).  Coney’s feed primarily on small fish and crustaceans. <br />
<br />
As with many other groupers, the females transform into males when they reach about 8 inches (20 cm). The Coney also has many color phases including a common phase shown here, a bicolor phase in which the upper body is dark and the lower body is pale, and a bright yellow phase with few spots.

  • A Christmas Tree Worm (Spirobranchus giganteus) extends its two “crowns” 49 feet below the surface of the Gulf of Mexico off the coast of Riviera Maya. Christmas tree worms are widely distributed throughout the world's tropical oceans, residing from the Caribbean to the Indo-Pacific.  The two Christmas tree-shaped multicolored spiral “crowns” per worm that protrude from the tube-like body are mouth appendages highly specialized for both feeding and respiration. These animals possess a complete digestive system, a well-developed closed circulatory system, and a nervous system with a central brain and many supporting ganglia.  The worms have two eyes that can detect light which are tucked under the crowns.  These adaptations allow Christmas tree worms to rapidly retract their crowns into their burrows at any sign of danger.  Interestingly, the nerves from these eyes do not go to the usual section of the brain associated with vision, and the light-sensitive proteins in the eyes called opsins are not the typical eye variety.  Christmas tree worms come in a wide variety of bright colors and are generally about 1.5 inches (3.8 cm) in length.

  • The spotted moray (Gymnothorax moringa) is a medium sized moray eel also referred to as conger, spotted eel, red moray, speckled moray, white cong, white-jawed moray, and white-chinned moray. Spotted moray eels are commonly 24 inches (60 cm) in length but can grow to more than 6.5 feet (2 m) and weigh 5.5 pounds (2.5 kg).  They inhabit the western Atlantic Ocean from North Carolina and Bermuda to Brazil, including the Gulf of Mexico and the Caribbean. They are also found around the mid- and eastern Atlantic islands as far south as St Helena.   Although spotted moray eels have been reported as deep at 660 feet (200 m), this individual is hiding 54 feet below the surface off the Riviera Maya in the Gulf of Mexico. Spotted morays are solitary animals, and usually hide in narrow crevices and holes in reef structures with only their heads peeking out as shown here.  They have double rows of teeth and are active during the day, feeding on crustaceans and fish at or near the sea bottom. Their bite can cause damage due to the rearward slanting teeth and potential toxins that may be released into the wound.

  • An Eastern Red-backed Salamander (Plethoon cinereus) walks across an "Iceberg" Hosta leaf.  This small salamander is found throughout the northeast United States.  It is lungless, and breathes through its moist skin. Unlike many salamanders, it spends its entire life on land, and lays its eggs on the moist forest floor. The young skip the typical aquatic stage and emerge as tiny terrestrial salamanders.

  • Multiple flocks of migrating Canada Geese (Branta canadensis) are silhouetted against the evening sky as the sun sets over Blackwater National Wildlife Refuge on the Eastern shore of Maryland, Halloween night, October 31, 1990.  Blackwater National Wildlife Refuge, encompassing over 27,000 acres of wetlands, is a major stop on the Atlantic Flyway for many types of waterfowl and other birds.  The refuge, established in 1933 as a waterfowl sanctuary, has been designated of “International Importance" by the Ramsar Convention as it supports over 250 bird species, 35 species of reptiles and amphibians, 165 species of threatened and endangered plants, and numerous mammals.  During winter migration, Blackwater Refuge is home to approximately 35,000 geese and 15,000 ducks. Fed by the Blackwater River and the Little Blackwater River, it consists of numerous freshwater impoundments, brackish tidal wetlands, open fields, and mixed evergreen and deciduous forests. The Blackwater name refers to the tea-colored waters darkened by tannins leached from the marsh peat soil through which they drain.

  • Discovered in 1878, Luray Caverns in Virginia has a spactacular array of both stalagtites (attached to the roof) and stalagmites (rising from the ground).  However, in this view, only stalagtites are present, each perfectly reflected in a shallow pool of water below.  The formations are formed when a solution of calcium carbonate releases carbon dioxide, resulting in precipitation of lime.  The crystallized calcite accumulates at the rate of one cubic inch every 120 years.

  • Although not a true spider, Daddy longlegs (order Opiliones) go by many names including harvestman, cellar spiders, granddaddy long-legs, carpenter spider, daddy long-legger, vibrating spider and skull spider.  Daddy longlegs are closely related to scorpions (order Scorpiones) but, because of their appearance, are often mistaken as spiders (order Araneida or Araneae). However, unlike true spiders, in which the body is divided into two distinct segments, daddy longlegs look as though they have only one segment because of a broad fusion that makes the juncture between the two segments almost indiscernible.  They are widely distributed and abundant in both temperate and tropical climates of both hemispheres.<br />
<br />
The body of a daddy longlegs is 0.6 to 23 mm (0.02 to 0.9 inch) long, although the bodies of most species are between 3 and 7 mm (0.12 and 0.28 inch). The legs can exceed 15 cm (5.9 inches) in length.  Many species of daddy longlegs are omnivorous, feeding on small insects, mites, spiders, snails, and vegetable matter.  Daddy longlegs typically have two eyes located on a central knob on the front of the body although certain types lack eyes. Eggs are laid in the soil in autumn and hatch with the warmth of spring. Many species of daddy longlegs live less than one year, although some may survive for several years.<br />
<br />
This individual was photographed on a screen door retroilluminated by the early morning sunlight where over 100 daddy longlegs had congregated to feed on small insects attracted to a nearby light left on overnight.

  • Muhlenbergia capillaris, commonly known as Pink Muhly Grass is a perennial warm-season grass that grows to be about 30–90 cm (0.98–2.95 ft) tall and 60–90 cm (2.0–3.0 ft) wide. The plant flower spikes are double layered with green leaf-like structures and purple-pink flowers that outgrow them from the bottom up in the autumn. The flowers are very feathery and add a cloudlike appearance to the top of the grass. During the summer, the leaves stay green, but during the fall they take on a more copper color. It is native to eastern North America.

  • On August 21, 2017 the path of the first solar eclipses over the Unites States in 38 years traversed approximately 2,500 miles of the country from Newport, Oregon to McClellanville, South Carolina.  Just outside Shoshoni, Wyoming, the path passed over Boysen Reservoir.  At this location, totality lasted 2 minutes and 22 seconds, being at its maximum about 11:40 am.  With the moon blocking the solar disk during totality, red flares called solar prominences become visible at the edge of the dark disk.  The red-glowing looped material is plasma, a hot gas composed of electrically charged hydrogen and helium. These prominences look small in relation to the size of the sun, but typically extend over many thousands of kilometers with the largest on record being estimated at over 800,000 kilometres (500,000 miles).  A prominence forms over timescales of about a day and may persist for several weeks or months.<br />
<br />
During the total solar eclipse, the sun’s outer atmosphere called the corona becomes visible as it extends millions of miles into space.  The corona consists of extremely hot ionized gases which exceed 1 million degrees Kelvin – 150- to 450-times hotter than the surface of the sun.  Being over 1 million million times less dense and much hotter than the sun’s surface and the solar prominences, the corona actually produces about one-millionth as much visible light, thus becoming visible from earth typically only during a total solar eclipse. The sun’s magnetic fields bend the corona into its remarkable shapes.<br />

  • An American Bullfrog (Rana catesbeiana) reveals only a heart-shaped head through a carpet of Duckweed (Lemnaceae) completely covering a small pond.<br />
<br />
The bullfrog is native to eastern North America with a natural range from the Atlantic Coast to as far west as Oklahoma and Kansas.  However, it has been introduced elsewhere where it is considered an invasive species, including Arizona, Utah, Colorado, Nebraska, Nevada, California, Oregon, Washington, Hawaii, Mexico, Canada, Cuba, Jamaica, Italy, Netherlands, France, Argentina, Brazil, Uruguay, Venezuela, Colombia, China, South Korea and Japan.  In some areas, the bullfrog is used as a food source.  <br />
<br />
Bullfrogs are voracious, ambush predators that eat any small animal they can stuff down their throats. Bullfrog stomachs have been found to contain rodents, reptiles, amphibians, crayfish, birds, bats, fish, tadpoles, snails and their usual food – insects.  Bullfrogs are able to jump a distance 10x their body length.  The female lays up to 20,000 eggs at a time that form a thin, floating sheet which may cover an area of 0.5 -1 m2 (5.4 - 10.8 sq ft). The embryos hatch in 3 - 5 days. Time to metamorphize into an adult frog ranges from a few months in the southern part of their range to 3 years in the north where the colder water slows development.  Maximum lifespan in the wild is 8 - 10 years, but one bullfrog lived for almost 16 years in captivity.<br />
<br />
Duckweed (Lemnoideae) are small flowering aquatic plants which float on or just beneath the surface of still or slow-moving bodies of fresh water. These plants lack obvious stems or leaves, and depending on the species, each plant may have no root or one or more simple rootlets.  Reproduction is mostly by asexual budding, however, occasionally three tiny flowers are produced for sexual reproduction.  The flower of the duckweed measures a mere 0.3 mm (1/100th of an inch) long.

  • Nudibranchs are soft-bodied marine mollusks which shed their shells after their larval stage.  The word "nudibranch" comes from the Latin nudus "naked" and the Ancient Greek βράγχια "gills".  Nudibranchs are often informally called sea slugs, <br />
<br />
All known nudibranchs are carnivorous with some feeding on sponges, hydroids, bryozoans, tunicates, barnacles, anemones, other sea slugs, sea slug eggs, or even their own species.  During evolution, nudibranchs lost their shells and developed alternative defense mechanisms. Some evolved to be well camouflaged, while others as seen here have intensely bright color patterns. Some sponge-eating nudibranchs concentrate the chemical defenses of the sponges in their bodies, rendering themselves distasteful to predators. Certain species produce their own protective chemicals, or release an acid mucus from the skin if physically touched.  <br />
<br />
Some nudibranchs that feed on prey which protect themselves with stinging cells called “nematocysts” can pass the intact nematocysts through their gut without harming the nudibranch or triggering the nematocysts.  The cells are then brought to the tips of the creature's “gills” (cerata).  The colors within the cerata are extensions of the digestive tract, often with a whitish tip where the nematocysts are concentrated, which now protect the nudibranch itself.<br />
<br />
Nudibranchs are hermaphroditic but cannot fertilize themselves. They typically deposit eggs within a gelatinous spiral resembling a ribbon. The number of eggs varies from 1 egg to 25 million!   The nudibranch lifespan ranges from a few weeks to a year depending on the species.<br />
<br />
The nudibranch (Flabellina salmonacea) pictured here is crawling on dulce (Palmaria palmata), an edible alga.
