A 3-D computer illustration of Eurypterid, more commonly known as a Sea Scorpion, from the mid Ordovician to late Permian (460 to 248 million years ago). Eurypterids (sea scorpions) are an extinct group of arthropods that are related to arachnids and include the largest known arthropods to have ever lived. They went extinct during the Permian–Triassic extinction event 252.17 million years ago. Their fossils have a near global distribution. Though purely an artistic interpretation, the structure of the animal is inferred through fossil images and scientific notation of what the species may have looked like within the environment in which they existed.

Blue-spot Mantis Haptosquilla stoliura occurs in the tropical Indo-West Pacific in shallow coastal or nearshore reefs in tidal pools and among hard coral fragments in the intertidal area. The iridescent blue patch on the first maxillipeds is distinctive. The max. length of this species seems to be incertain. Some indicate 6.5cm as max. length, others 11.5cm. The length of this specimen is probably 10cm. \nThe ability of Mantis species to see circularly polarised light has led to studies to determine if the mechanisms by which their eyes operate can be replicated for use in reading optical information storage devices. \nTriton Bay, West Papua Province, Indonesia, \n3°54'41.05 S 134°7'18.205 E at 15m depth

Orconectes limosus, Eastern Crayfish, Or Delcore Crayfish is a species of crayfish in the family Cambaridae. It is native to the east coast of North America, from Maine to the lower James River, Virginia, but has also been introduced to Europe. It is unusual in that it lives in silty streams, rather than the clear water usually preferred by crayfish. Like Pacifastacus leniusculus, another invasive North American crayfish, O. limosus carries crayfish plague and is a threat to native crayfish.
