pelago-, pelag- +

Relating to, or living at intermediate ocean depths between about 200 and 1,000 meters (656 and 3,280 feet); such as, mesopelagic organisms.

Inhabiting shallow coastal waters over the continental shelf.

1. Pertaining to organisms that migrate into the upper surface waters at night.
2. Bathypelagic and appearing at the surface only at night.

Bathypelagic refers to creatures that live in deep water below the level of light penetration, between 1 000 meters and 4 000 meters deep.

The biogeographic realm or zone that comprises the open seas and oceans, including water of all depths.

1. Of, relating to, or living in open oceans or seas rather than waters adjacent to land or inland waters; such as, pelagic birds.
2. Living or growing at or near the surface of the ocean, far from land, as certain organisms.
3. Of or pertaining to the sea; marine; such as, pelagian shells.

The pelagic zone of the ocean begins at the low tide mark and includes the entire oceanic water column. The pelagic ecosystem is largely dependent on the phytoplankton inhabiting the upper sunlit regions, where most ocean organisms live.

Biodiversity decreases sharply in the unlit zones where water pressure is high, temperatures are cold, and food sources scarce. Pelagic waters are divided, in descending order, into the epipelagic, mesopelagic, bathypelagic, abyssopelagic, and hadopelagic zones.

A rarely used term for seasickness.

A reference to coal derived from a submerged forest or from driftwood.

In biology, thriving in the open surface waters of the sea.

A plant living at the sea surface.

1. An infection characterized by gastrointestinal disturbances, erythema (redness of the skin due to capillary dilatation, particularly of exposed areas) followed by desquamation (the shedding of the cuticle in scales or of the outer layer of any surface), and nervous and mental disorders; may occur because of a poor diet, alcoholism, or some other disease causing impairment of nutrition; commonly seen when corn (maize) is a main nutrient in the diet, resulting in a deficiency of niacin.
2. An endemic disease (frequent among the peasantry of Southern Europe; especially, Lombardy, often attributed to eating diseased maize), in which the skin reddens, dries, and cracks, and the epidermis peels off in bran-like scales; the digestive organs and central nervous system are affected, and the disease often ends in insanity

The island of Java.

A reference to organisms that are normally benthic, but which have been carried up into the water column by chance factors.
