Hentzia, Orange Jumping Spider, Coventry, CT

$19.00 – $400.00

The jumping spider family (Salticidae) contains over 600 described genera and more than 5800 described species,[1] making it the largest family of spiders with about 13% of all species.[2] Jumping spiders have some of the best vision among arthropods and use it in courtship, hunting, and navigation. Although they normally move unobtrusively and fairly slowly, most species are capable of very agile jumps, notably when hunting, but sometimes in response to sudden threats or crossing long gaps. Both their book lungs and tracheal system are well-developed, and they use both systems (bimodal breathing). Jumping spiders are generally recognized by their eye pattern. All jumping spiders have four pairs of eyes, with the anterior median pair being particularly large.

Oribatida Mite, Epidamaeus coxalis

$19.00 – $400.00

Oribatida (formerly Cryptostigmata), also known as moss mites or beetle mites,[1] are an order of mites, in the “chewing Acariformes” clade Sarcoptiformes. They range in size from 0.2 to 1.4 millimetres (0.008 to 0.055 in).[1]

Oribatid mites generally have low metabolic rates, slow development and low fecundity.[1]Species are iteroparous with adults living a relatively long time; for example, estimates of development time from egg to adult vary from several months to two years in temperate forestsoils.[1] Oribatid mites have six active instars: prelarva, larva, 3 nymphal instars and the adult.[1] All these stages after the prelarva feed on a wide variety of material including living and dead plant and fungal material, lichens and carrion; some are predatory, but none is parasitic and feeding habits may differ between immatures and adults of the same species.

Mite on Beetle Host

$19.00 – $400.00

In biology/ecology, parasitism is a non-mutual relationship between species, where one species, the parasite, benefits at the expense of the other, the host. Traditionally parasite (in biological usage) referred primarily to organisms visible to the naked eye, or macroparasites (such as helminths). Parasites can be microparasites, which are typically smaller, such as protozoa,[1][2] viruses, and bacteria.[3] Examples of parasites include the plants mistletoe and cuscuta, and animals such as hookworms.

Polychaeta, Bristle Worm

$19.00 – $400.00

The Polychaeta /ˌpɒlɪˈkiːtə/, also known as the bristle worms or polychaetes, are a paraphyletic class of annelid worms, generally marine. Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin. As such, polychaetes are sometimes referred to as bristle worms. More than 10,000 species are described in this class. Common representatives include the lugworm (Arenicola marina) and the sandworm or clam worm Alitta.

Hawaiian Bobtail Squid Theme (Juvenile): Research by Dr. Spencer Nyholm

$19.00 – $400.00

The Nyholm lab studies beneficial host-microbe interactions between the Hawaiian bobtail squid, Euprymna scolopes, and the bioluminescent bacterium, Vibrio fischeri. Hawaiian bobtail squid are nocturnal predators, remaining buried under the sand during the day and coming out to hunt for shrimp at night neat coral reefs. The squid have a light organ on their underside that houses a colony of glowing bacteria (V. fischeri). The squid uses this bacterial bioluminescence in a form of camouflage called counter-illumination, masking it’s silhouette by matching moonlight and starlight; thus hiding from predators swimming below. The light organ is attached to the ink sac and it can use this ink like a type of shutter to control the amount of light. This likely helps the squid adjust to variable light conditions, for example cloudy nights or a full vs. new moon. In this image of a juvenile squid, you can clearly see the bi-lobed light organ and ink sac in the center of the squid’s mantle cavity. 

The Hawaiian bobtail squid lay their eggs in clutches on the sea floor, where they take approximately three weeks to develop. This series of macropod images allows us to see the developing squid and monitor embryogenesis. Once the squid hatch, V. fischeri from seawater colonize the light organ within hours. This macropod image allows us to see a close-up view of the ciliated appendage-like structure found on the surface of the juvenile squid’s light organ. Once the squid hatches, the cilia assist in bringing V. fischeri in the seawater to pores at the base of the light organ. These pores lead to inner crypts, where only V. fischeri can enter and colonize. V. fischeri is a relatively rare member of the seawater bacterial community, making up less than 0.1%. The Nyholm lab is trying to understand how the squid’s immune system can differentiate between the symbiont and all the other different kinds of bacteria in seawater.

While the light organ of the squid exemplifies a highly specific beneficial relationship between bacteria and host to provide camouflage at night, this organ is only found in some squid species. All squid, however, are capable of another type of camouflage, cryptic coloration. Squid skin contains special pigmented cells called chromatophores that can change the overall color of the squid in seconds. Each chromatophore contains pigment granules surrounded by nerve and muscle fibers. When these muscles are contracted, the pigment sac expands, creating a larger surface area of color. When the muscles relax, the pigment sac can shrink to a small dot, 15 times smaller than their expanded size, hiding the color. In these macropod images you can see relaxed chromatophores on the mantle and contracted chromatophores around the eyes. The macropod images allow us to see these pigment cells in great detail.
