The Labrador duck is an extinct North American duck species. It has the distinction of being the first known endemic North American bird species to become extinct after the Columbian Exchange, with the last known sighting occurring in 1878 in Elmira, New York. It was already a rare duck before European settlers arrived, and as a result of its rarity, information on the Labrador duck is not abundant, although some, such as its habitat, characteristics, dietary habits and reasons behind its extinction, are known. There are 55 specimens of the Labrador duck preserved in museum collections worldwide.
The order Cephalaspidea, also known as the headshield slugs and bubble snails, is a major taxon of sea slugs and bubble snails, marine gastropod mollusks within the larger clade Euopisthobranchia.

Macrocystis is a monospecific genus of kelp with all species now synonymous with Macrocystis pyrifera. It is commonly known as giant kelp or bladder kelp. This genus contains the largest of all the Phaeophyceae or brown algae. Macrocystis has pneumatocysts at the base of its blades. Sporophytes are perennial and the individual may live for up to three years; stipes/fronds within a whole individual undergo senescence, where each frond may persist for approximately 100 days. The genus is found widely in subtropical, temperate, and sub-Antarctic oceans of the Southern Hemisphere and in the northeast Pacific from Baja California to Sitka, Alaska. Macrocystis is often a major component of temperate kelp forests.

Polinices bifasciatus, or two-banded moon snail, is a species of gastropod mollusc. The animal was first described to science in a work authored by English biologists Edward Griffith and Edward Pidgeon. This was a multi-volume translation of George Cuvier's, Le Règne Animal (1830). The Griffith and Pidgeon work went beyond translation and added a supplement that included the description of Polinices bifasciatus. The description of Polinices bifasciatus is attributed to John Edward Gray. It reads, in its entirety, "Pale brown, with two narrow bands".
