Sharks Preserved

Sharks Preserved

Sharks are a group (superorder Selachimorpha) of fish, with a full cartilaginous skeleton and a streamlined body, with normally 5, but up to 7 (depending on species) gill slits along the side of, or beginning slightly behind, the head (in some species, a modified slit called a spiracle, is located just behind the eye), dermal denticles covering the body to protect from damage, parasites and improve fluid dynamics, and rows of replaceable teeth in the mouth.

Sharks have keen olfactory senses, with some species able to detect as little as one part per million of blood in seawater. They are even more attracted to the chemicals found in the gut of many species, and often linger near or in sewage outfalls. Some species, such as Nurse sharks, have external barbels that greatly increase their ability to sense prey. The short duct between the anterior and posterior nasal openings are not fused like in bony fish

Injected specimens are injected with dye highlighting specific systems. Single injection highlights the arterial system, Double injection includes the hepatic portal system, triple adds the venous system.

Skate Plain

Skate Plain

Skates are cartilaginous fishes belonging to the family Rajidae in the superorder Batoidea of rays. They are carnivorous, feeding mostly on smaller fish and crustaceans. They have flat pectoral fins continuous with their head, two dorsal fins and a short, spineless tail.

They are benthic (bottom-dwelling) and are found throughout the world from continental shelves down to the abyssal zone. They are oviparous fishes, laying eggs in a horny case known as a mermaid's purse (PICTURED TO THE RIGHT). It is thought that egg-laying in skates is an evolutionary reversal, that is, skates are descended from ovoviviparous ancestors.

The common skate, Dipturus batis, is the largest found in British waters. It has a long, pointed snout. However, the most common skate in British seas is the thornback ray, Raja clavata. They are frequently caught by trawling.

Stingray Plain

Stingray PlainDasyatids are common in tropical coastal waters throughout the world, and there are fresh water species in Asia (Himantura sp.), Africa, and Florida (Dasyatis sabina). Most dasyatids are neither threatened nor endangered. The species of the genera Potamotrygon, Paratrygon, and Plesiotrygon are all endemic to the freshwaters of South America.

Dasyatids swim with a "flying" motion, propelled by motion of their large pectoral fins (commonly referred to as "wings").

Their stinger is a razor-sharp, barbed or serrated cartilaginous spine which grows from the ray's whip-like tail (like a fingernail). It is coated with a toxic venom. This gives them their common name of stingrays, but that name can also be used to refer to any poisonous ray.
