Ward's® PURE Preserved Specimens - the best dissection experience from start to finish.

Limulus polyphemus. A true "living fossil", this representative of the class Meristomata is one of only five living still in existence. The crab is the most widely studied Meristomata because of their large compound eyes and their copper-based blue blood. It thrives in a marine aquarium such as WARD’S Marine Touch Tank. Culture instructions are included. Size: 1–3". Note: Shipped overnight. Additional shipping fee applies.

When minerals, rocks, and fossils cannot be accurately identified by macroscopic observation and testing, thin section slides can reveal the composition and structure of the specimens on a microscopic level.

Scoria is a dark-colored rock formed from lava with a high gas content.

This organism is commonly isolated from human nasopharyngeal mucosa

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.

Feldspar group; pink cleavages showing perthitic texture, common potassium feldspar, Mohs’ hardness of 6.
