Copepod, Tolland CT

$19.00 – $400.00

Copepods (/ˈkoʊpɪpɒd/; meaning “oar-feet”) are a group of small crustaceans found in the sea and nearly every freshwater habitat. Some species are planktonic (drifting in sea waters), some are benthic (living on the ocean floor), and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators.

As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult and then, after more molts, achieves adult development. The nauplius form is so different from the adult form that it was once thought to be a separate species.

Gneiss from Queenstown, New Zealand

$19.00 – $400.00

Gneiss ( /ˈnaɪs/) is a common distributed type of rock formed by high-grade regional metamorphic processes from pre-existing formations that were originally either igneous or sedimentary rocks. It is often foliated (composed of layers of sheet-like planar structures). The foliations are characterized by alternating darker and lighter colored bands, called “gneissic banding”.

Polished K Feldspar-Epidote-Quartz-Biotite Matrix

$19.00 – $400.00

Feldspars are a group of rock-forming tectosilicateminerals that make up about 41% of the Earth‘s continental crust by weight.[2]

Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock.[3] Rock formed almost entirely of calcic plagioclase feldspar (see below) is known as anorthosite.[4] Feldspars are also found in many types of sedimentary rocks.[5]

Mayfly Choroterpes sp.

$19.00 – $400.00

Leptophlebiidae is a family belonging to the Ephemeropterans that are commonly known as the prong-gilled mayflies or leptophlebiids. It is the only family in the superfamilyLeptophlebioidea.[1] In North America they occur with about 70 species from 9 genera in freshwater streams and lakes; in Europe they are somewhat less diverse. Globally, this family is much more prevalent and diverse, with about 2000 different species. Leptophlebiids are easily recognized by the forked gills present on the larvae‘s abdomen, thus their common name.
