Saw Fish Rostrum

$19.00$400.00

Sawfishes, also known as carpenter sharks, are a family of rayscharacterized by a long, narrow, flattened rostrum, or nose extension, lined with sharp transverse teeth, arranged in a way that resembles a saw. Several species of sawfishes can grow to about 7 m (23 ft).[2][3][4] The family as a whole is largely unknown and little studied. The Pristidae are the only living family within the order Pristiformes, whose name comes from the Ancient Greek: πρίστης, translit. prístēs, lit. ‘saw, sawyer’.[5]

Poeciliopsis prolifica (Embryo)

$19.00$400.00

Poeciliopsis prolifica, or the blackstripe livebearer, is a species of small freshwater fish in the family Poeciliidae. It is endemic to Mexico.[3] It is a viviparousspecies and the female can have several clutches of young developing internally at the same time, hence the specific name prolifica, from the Latin proles, “offspring” and ferax, “rich, fruitful” in reference to the great number of young produced.

Quartz Crystals (sand) on Fish Vertebrae

$19.00$400.00

Fish bone is any bone of a fish. Fish bone also includes the bony, delicate parts of the skeleton of bony fish, such as ribs and fin rays, but especially the ossification of connective tissue lying transversely inclined backwards to the ribs between the muscle segments and having no contact with the spine.

Not all fish have fish bones in this sense; for instance, eels and anglerfish do not.

There are several series of fish bones: Epineuralia, Epicentralia, Epipleuralia and Myorhabdoi.

Fin Structure of a Cleared and Stained Fish, Hudson River Valley

$19.00$400.00

Staining is an auxiliary technique used in microscopy to enhance contrast in the microscopic image. Stains and dyes are frequently used in biology and medicine to highlight structures in biological tissues for viewing, often with the aid of different microscopes. Stains may be used to define and examine bulk tissues (highlighting, for example, muscle fibers or connective tissue), cell populations (classifying different blood cells, for instance), or organelles within individual cells.

Otolith

$19.00$400.00

An otolith (Greek: ὠτο-, ōto- ear + λῐ́θος, líthos, a stone), also called statoconium or otoconium or statolith, is a calcium carbonate structure in the saccule or utricle of the inner ear, specifically in the vestibular labyrinth of vertebrates. They have been identified in both extinct and extant vertebrates.[1]Counting the annual growth rings on the otoliths is a common technique in estimating the age of fish. The saccule and utricle, in turn, together make the otolith organs.

Fish Scale

$19.00$400.00

The skin of most fishes are covered with scales, which, in many cases, are animal reflectors or produce animal coloration. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from.

Spiracle 100x, Ixodes scapularis (Deer Tick)

$19.00$400.00

Ixodes is a genus of hard-bodied ticks (family Ixodidae). It includes important disease vectorsof animals and humans (tick-borne disease), and some species (notably Ixodes holocyclus) inject toxins that can cause paralysis. Some ticks in this genus may transmit the pathogenic bacterium Borrelia burgdorferi[3] responsible for causing Lyme disease. Additional organisms that may be transmitted by Ixodes are parasites from the genus Babesia which cause babesiosis, and bacteria from the related genera Anaplasma which cause anaplasmosis.

Engorged Dog Tick

$19.00$400.00

Dermacentor variabilis, also known as the American dog tick or wood tick, is a species of tick that is known to carry bacteria responsible for several diseases in humans, including Rocky Mountain spotted fever and tularemia (Francisella tularensis). It is one of the most well-known hard ticks. Diseases are spread when it sucks blood from the host, which could take several days for the host to experience some symptoms.
