Craniata (sometimes Craniota) is a proposed clade of chordate animals that contains the Myxini (hagfish), Petromyzontida (including lampreys), and Gnathostomata (jawed vertebrates) as living representatives. As the name suggests, Craniata are animals with a (hard bone or cartilage) skull in Chordata.

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)

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.
