Bullfrogs (Preserved)

The American Bull Frog (Rana catesbeiana) is an aquatic frog, a member of the family Ranidae, or "true frogs", native to much of North America.

Bull frogs are large amphibians and can grow to a body length of 6 inches (15 cm) with a weight of 1.5 lb (750 g). Females are typically larger than males. They are generally varying shades of green or brown, with dark brown, dark green, or black blotching and a yellow or white underside.

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

Grassfrogs (Preserved)

Leopard frogs, which are also called meadow frogs and grass frogs, are a collection of so-called true frogs within the genus Rana. Once abundant in North America and Canada, their population has declined in recent years due to pollution and deforestation. Leopard frogs are often used as environmental indicator species because of their heightened sensitivity to chemical pollutants found in the air and water and are commonly used as dissection specimens in biology classrooms.

Leopard frogs are recognized by their green or brown coloration with distinct light-edged dark spots across the back and pure white underside. They also have a characteristic line of raised glandular skin, called the dorsolateral ridge, extending from each eye to the groin.

Injected specimens are injected with dye highlighting specific systems. Single injection highlights the arterial system, double injection includes the venous system.

Amphiuma (Congo Eel) (Preserved)

Amphiuma is a genus of aquatic salamanders, the only genus within the family Amphiumidae. They are also known as "congo eels" or "congo snakes", which are zoologically incorrect designations.

Amphiumas have an elongated body, generally grey-black in color. They do have legs, but they are very small, while amphiumas can be up to 1 m long, but their legs measure only 2 cm. Therefore, they can resemble eels.

Larvae have external gills. After four months these external gills disappear and the lungs begin to work. One pair of gill slits is retained and never disappears, so the metamorphosis remains incomplete.

Necturus

The Common Mudpuppy (Necturus maculosus) is a species of aquatic salamander found throughout the northeastern United States, and parts of Canada. Mudpuppies prefer shallow water with lots of places to hide, but have been found at depths of up to 90 feet.

The mating season is late autumn however eggs are not laid until late spring when 50 to 100 eggs are deposited in a nest cavity under a rock or other object. It takes 1 to 2 months for the eggs to hatch and 4 to 6 years for the young to reach maturity. Mudpuppies may live for up to 20 years. The common mudpuppy is nocturnal, but can be active in the day in muddy or weed-choked waters. It is carnivorous and feeds on fish, fish eggs, crayfish, insects, and molluscs.
