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.

The fresh water supply of the Southern United States has been invaded by the zebra mussel, which has a huge economic and environmental impact on the waters it invades.

(Tectura sp.) Limpets are mollusks living in the intertidal to subtidal zones.  They can be found on rocks above the tide zone along shorelines.  They come in a variety of shapes and designs.  Their range is from northern Alaska to southern California.  They feed at night eating seaweed.  They are often eaten by sea stars.
