These two great ocean currents interact creating huge foamy breakers which constantly advance towards the shore, and building submarine shoals rich in fish, shrimps, and an amazing variety of other marine life forms.

These oceans and seas were populated with now extinct marine reptiles, ammonites and rudists, while dinosaurs continued to dominate on land.

These marine worms are nutritionally dependent on their symbiotic chemoautotrophic bacteria lacking any digestive or excretory system ( no gut, mouth or nephridia ).

These new insurance contracts allowed insurance to be separated from investment, a separation of roles that first proved useful in marine insurance.

These disputes are in part about the control of marine and natural resources, such as possible reserves of crude oil and natural gas.

These microorganisms including bacteria and the broad range of organisms that form the marine microbial loop, responsible for regulating much of the oceans ' biogeochemistry.

These include Bamfield Marine Station, a major centre for teaching and research in marine biology ; TRIUMF, a powerful cyclotron used in subatomic physics and chemistry research.

These are marine gastropod mollusks.

These fossils, known collectively as the lobopods, were marine and probably represent a stem group to the

These creatures, which are about the size of a lentil, are eaten by various marine species, including a wide variety of fish that are, in turn, consumed by penguins and polar bears.

These people survived by eating marine life.

These are six Prochlorococcus strains, seven marine Synechococcus strains, Trichodesmium erythraeum IMS101 and Crocosphaera watsonii WH8501.

These two factors make them an integral component of the marine environment.

These were also useful for marine artists, and it is clear that from Dutch Golden Age Painting onwards extensive use of models was made by artists.

These non-volcanic rock beds are rich with fossils of prehistoric marine life once native to the inland sea that covered the area some 280 million years ago, ranging from well preserved molluscan shells, to small fish.

These expeditions laid the foundations of an extensive knowledge of the distribution of marine life.

These monitor lizards ' marine relatives, the mosasaurs, were apex predators in late Cretaceous seas.

These include standard map symbols for marine navigation aids such as buoys, marinas and anchorages, as well as such land-based symbols as churches, bridges, shopping centers, parks, and tunnels.

These are common in both freshwater and marine environments, and many live attached to aquatic plants and animals.

These form a small component of marine sediments, and are known as microfossils from as far back as the early Cretaceous.

These banks can be hazard for marine navigation because they are constantly changing due to tidal currents.

These are found in both freshwater and marine environments, and most genera are sessile, attached by posterior stalks.

These researches had an important bearing on some of the infusorial earths used for polishing and other economic purposes ; they added, moreover, largely to our knowledge of the microorganisms of certain geological formations, especially of the chalk, and of the marine and freshwater accumulations.

These are large marine ducks The drakes have body plumage showing varying amounts of black and white, and distinctive head patterns. Females are brown.

These normally play an important role in controlling the growth of algae and also forage on detritus that accumulates as sediment on the bottom.

These types include the endosymbiotic events of cyanobacteria, red algae and green algae, leading to the hypothesis of the supergroups Archaeplastida, Chromalveolata and Cabozoa respectively.

These are specialized heterokont algae, related to golden algae, diatoms, brown algae, and the like, which have microtubule-supported tentacles.

These nutrients are typically found in edible plants, especially colorful fruits and vegetables, but also other organisms including seafood, algae, and fungi.

These pigments are embedded in plants and algae in special antenna-proteins.

These organisms include drifting animals, plants, archaea, algae, or bacteria that inhabit the pelagic zone of oceans, seas, or bodies of fresh water.

These algae, known as phytoplankton, are single-celled protists, plant-like organisms that can form dense, visible patches near the water's surface.

These blooms are recognizable by large blades of algae that may wash up onto the shoreline.

These algae assimilate the other necessary nutrients needed for plants and animals.

These algae strengthen the reef structure by depositing limestone in sheets over the reef surface.

These operate like ' rakes ', scraping algae and gathering the resultant detritus.

These are shallow, brackish ponds with benthic algae, usually used as feed.

These omnivorous or herbivorous species can be useful in the household aquarium as scavengers, because they eat algae and debris.

These flamingos are filter-feeders and their diet ranges over the entire spectrum of available foods, from fish to invertebrates, from vascular plants to microscopic algae.

These issues have now largely been resolved though some toxic algae remains in some of the dock areas in the Bay.

These limestones contain the aboundant fossils of shallow marine foraminifera, coral, mollusks, and algae.

These flamingoes, the single large flock in East Africa, gather along saline lakes in the region, where they feed on Spirulina ( a blue-green algae with red pigments ).

These filters are porous and allow water, monovalent species ( Na +, Cl -), dissolved organic matter, small colloids and viruses through but do not allow particles, sediment, algae or large bacteria through.

These toxic compounds are not produced by spirulina itself, but may occur as a result of contamination of spirulina batches with other, toxin-producing, blue-green algae.

These skeletons persist, together with the mass of coralline algae that is essential for reef integrity.
