Those larvae which remain pelagic until better able to compete at the sea-bottom become the adults which fix the time of metamorphosis on their progeny.
Among the free-swimming or migratory pelagic fishes, the number of vertebrae is usually greater than among their relatives of local habits.
Their differences in distribution are largely vertical, some living at greater depths than others, and they shade off by degrees from bathybial into semi-bathybial, and finally into ordinary pelagic and ordinary shore types.
The pelagic types have reached a species of equilibrium in distribution.
Some pelagic fishes, especially flying fishes and fishes allied to the mackerel, swim long distances to a region favorable for a deposition of spawn.
Their distribution in space is more definite than that of the pelagic and bassalian types, and they may be more definitely assigned to geographical areas.
Pelagic Organisms The transparency of pelagic organisms is frequently cited as exemplifying cryptic colouring.
Besides the internecine warfare which is continually going on amongst the smaller surface organisms, they are devoured wholesale by the larger pelagic fish, and by whales and other Cetacea.

I may add that Scoresby remarks that green water abounding with pelagic animals is invariably found in a certain part of the Arctic Sea.
The open-sea or pelagic haunt includes all the brightly illumined surface waters beyond the shallow water of the shore area.
It is hardly necessary to say that the pelagic plants are more abundant near the surface, and that below a certain depth the population consists almost exclusively of animals.
This remarkable change of colour, which was observed by the Discovery Expedition in much the same place, was supposed to be due to a large mass of pelagic fauna called plankton.
The Americans placed the responsibility with the pelagic sealer; the British, with the lessees through their methods of sealing on land.
The reduction of the males effected on the islands causes an enhanced proportion of females to be found in the pelagic catch; hence this proportion, if it vary from no other cause, varies at least with the catch on the islands.
It is a significant fact that in four years, under regulations which permit the pelagic sealer to take all he can get, the product of his industry has fallen to less than one half.
Again, this date marks the advent ofpelagic sealing in Bering Sea, and the beginning of that remarkable expansion of the industry which culminated ten years later in 1894.
The pelagic industry is conducted in an orderly manner, and in a spirit of acquiescence in the limitations imposed by law.
It is merely a question of how to get rid of the destructive agency of pelagic sealing.
Should the pelagic catch continue to decrease, as it must, it will eventually come within the margin of six and two thirds per cent.
The decline of the herd is thus made synonymous with the rise of pelagic sealing.
If pelagic sealing were stopped to-day the herd would naturally begin to increase.
Pelagic sealing not only destroys the herd, but it is necessarily self-destructive because it preys upon its own capital.
We have here the necessary condemnation of pelagic killing expressed in equally full and frank terms.
These facts are left to be inferred from the "reductions in surviving pups" here noted and from the admission that "nursing and pregnant females" are taken in the pelagic catch.
There is no comfort in this prospect, either for the pelagic sealer or for the owner of the herd, and it takes no note of the injury which has been accomplished in the past, much less of possible restoration in the future.
As the Rattlesnake sailed through the tropical seas Huxley came in contact with the very peculiar and interesting inhabitants of the surface of the sea, known now to naturalists as pelagic life or "plankton.
Many other Ascidians pass their whole life as pelagic creatures.
Some pelagic Ostracods of the family Halocypridae have been observed to emit clouds of a luminous secretion from a gland in the neighbourhood of the mouth.
Instead of beginning life as minute pelagic zoeae, they leave the shelter of the mother's abdomen as perfectly-formed little Crabs (Fig.
A number of pelagic Copepoda have been shown by Giesbrecht to secrete, from special glands on the surface of the body, a substance which becomes luminous on coming in contact with the water.
Many of the modifications in structure characteristic of pelagic animals may be traced to the necessity for keeping continuously afloat with a minimum of exertion.
The Mid-Atlantic swarms with pelagic Mollusca, and, in moderate depths, the shells of these are constantly mixed with the Globigerina ooze, sometimes in number sufficient to make up a considerable portion of its bulk.
This treaty was accompanied by an agreement prohibiting pelagic sealing pending the arbitration, and a vigorous effort was made during this season to drive out all poaching sealers from the Bering Sea.

In a decapod form with pelagic larvae, described by Grenacher (No.
Consequently to prohibit pelagic sealing would have been to exclude Canada from the industry.
The negotiations were wrecked upon the question ofpelagic sealing.
On the other hand, pelagic sealing, being a method of promiscuous slaughter, was illegitimate; it was contra bonos mores and analogous to piracy.
Owing to the scarcity of seals and international difficulties concerning pelagic sealing in Bering Sea, where the greatest number have been taken, the business of seal-hunting is losing favour.
On the whole, then, it would appear that in so far as modern developments affect the problem, they certainly render pelagic operations far more difficult and uncertain than they used to be.
It may be terminal or it may be pelagic, terminal attack being the more profitable, but demanding the greater force and risk, and pelagic attack being the more uncertain, but involving less force and risk.
For such pelagic operations her movement was practically unrestricted.
The loss of radius of action therefore, though it does not increase the power of defence, sensibly lessens that of attack by pelagic operations.
So far as clays are concerned, the action of the sea is both erosive and depository, though the sedimentation in it being that of the pelagic ooze at great depths the clayey material is quite inaccessible.
The Gannet is a thoroughlypelagic bird, and only comes to the land to breed, retiring once more to the sea as soon as its young can fly.
These birds are the most pelagic of all, and only visit the land to breed.

Certain pelagic plants present only a very weak, feeble consistence; a great number are transformed by ebullition into a sort of jelly.

The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "pelagic" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: marine; maritime; nautical; navigational; oceanic; pelagic; salty; seafaring
