* Pelagic deposits, which contain the remains of organisms that sink to the ocean floor, include red clays and Globigerina, pteropod, and siliceous oozes.

In Devonian | Late Devonian vertebrate speciation, descendants of Pelagic zone | pelagic Sarcopterygii | lobe-finned fish – like Eusthenopteron – exhibited a sequence of adaptations: * Panderichthys, suited to muddy shallows ; * Tiktaalik with limb-like fins that could take it up onto land ; * Tetrapod | Early tetrapods in weed-filled swamps, such as: ** Acanthostega which had feet with eight digits, ** Ichthyostega with limbs.

Pelagic species are filter feeders while benthic species, common for the tribe Erythropini, have been observed feeding on small particles which they collect by grooming their body surface and legs.

Pelagic squid fisheries took over which use pelagic trawls that are harmful to dusky, short-beaked common dolphins, and Commerson ’ s dolphins.

Pelagic plastic pieces in the center of our ocean ’ s gyres outnumber live marine plankton, and are passed up the food chain to reach all marine life.

On land, Pelagic Cormorants are rather clumsy and walk with the high-stepped waddling gait typical for all Sulae except darters ; after landing they often scratch the ground, as is typical for cormorants.

Like all cormorants, this includes stretching the gular sac with the hyoid bone and repeated " yawning "; as in many but not all cormorants, the Pelagic Cormorant's display furthermore includes arching the neck and hopping, lifting the folded wings and rapidly fluttering them to show the white thigh patches.

# Partner with the South Atlantic Fishery Management Council ( SAFMC ) to promote implementation of the Fishery Management Plan for Pelagic Sargassum Habitat of the South Atlantic Region.

Pelagic sea cucumber s, often confused with jellyfish, have webbed swimming structures enabling them to swim up off the surface of the seafloor and journey as much as 1000 metres up the water column

Pelagic trawls are typically much larger than bottom trawls, with very large mesh openings in the net, little or no ground gear, and little or no chaffing gear.

Pelagic life decreases with increasing depth.

Pelagic birds, also called oceanic birds, are birds that live on the open sea, rather than around waters adjacent to land or around inland waters.

Pelagic fish are fish that live in the water column of coastal, ocean and lake waters, but not on or near the bottom of the sea or the lake.

Pelagic fish live near the surface or in the water column of coastal, ocean and lake waters, but not on the bottom of the sea or the lake.

Pelagic habitats are found near the surface or in the open water column, away from the bottom of the ocean.

Pelagic habitats are intrinsically shifting and ephemeral, depending on what ocean currents are doing.

The Pelagic Cormorant ( Phalacrocorax pelagicus ), also known as Baird's Cormorant, is a small member of the cormorant family Phalacrocoracidae.

Analogous to other smallish cormorants, it is also called Pelagic Shag occasionally.

In this case, the Pelagic Cormorant would probably be placed in Compsohalieus.

In the former case, the large naked face " mask " and light bill of P. urile can be easily recognized, in the latter case its larger size ( though male Pelagic Cormorants can be as large as female Red-faced Cormorants ).

The Pelagic Cormorant inhabits the shores and the neritic zone of the North Pacific.

Pelagic Cormorants ( presumably P. p. resplendens ) at Kitsap Peninsula ( Washington ( state ) | Washington, USA ) preening after fishing.

The Pelagic Cormorant breeds on rocky shores and islands.

Other retailers sell computer clones made by Seiko ( Apeks, Cressi, Dive Rite, ScubaPro, Tusa, Zeagle ) or Pelagic Pressure Systems ( Beuchat, Genesis, Seemann, Sherwood ) or Benemec Oy ( A. P. Valves ).

Also, in the case of Pelagic animals, he showed a relation between death temperature and the quantity of solid constituents of the body.

* Benthic Ecosystems Department, which studies the biology of ocean floors at a variety of depths.

Ecosystems provide a variety of goods and services upon which people depend ; the principles of ecosystem management suggest that rather than managing individual species, natural resources should be managed at the level of the ecosystem itself.

Ecosystems provide a variety of goods and services upon which people depend.

Its ecosystem is specifically surveyed by the Management Team of Ecosystems ( Equipo de Manejos de Ecosistemas ) which is led by Pedro Rios.

In 1991, BIOS-3 became a part of the International Center for Closed Ecosystems, which was formed as a subdivision of Institute of Biophysics, Russian Academy of Sciences, Siberian Branch.

A feature distinguishing it from prior economic regimes is the direct valuation of natural capital and ecological services as having economic value ( see The Economics of Ecosystems and Biodiversity and Bank of Natural Capital ) and a full cost accounting regime in which costs externalized onto society via ecosystems are reliably traced back to, and accounted for as liabilities of, the entity that does the harm or neglects an asset.

The museum's Powdermill Nature Reserve was established in 1956 to serve as a field station for long-term studies of natural populations, and now forms the core of the museum's Center for Biodiversity and Ecosystems.

Ecosystems regenerate after a disturbance such as fire, forming Mosaic ( ecology ) | mosaics of different age groups structured across a Landscape ecology | landscape.
