Insectivorous species occur among aquatic plants; e.g.

In freshwater lakes and ponds, especially if the water is stagnant, aquatic plants are abundant.

If you do your part to prevent pollution in your area, then you'll be helping to protect aquatic life.

Very few aquatic plants are pollinated under water, but this is wellknown to occur in species of Zostera and of Naias.

There are numerous species of aquatic birds.

Such places are frequented by numerous flocks of aquatic birds, which resort thither in search of fish and mollusca.

The lakes are the homes of a variety of aquatic birds.

The Serra da Estrella has a rich alpine flora, and the lagoon of Aveiro contains a great number of aquatic plants.

Its large size, aquatic habits, partially webbed hind-toes, and the smooth, broad, orange-coloured incisors, are sufficient to distinguish this rodent from the other members of the family Capromyidae.

Although subsisting to a considerable extent on aquatic plants, these rodents frequently come ashore to feed, especially in the evening.

Besides these the group also includes a multitude of related forms which, from their aquatic habits and generally inconspicuous size, and from the fact that they are commonly neither edible nor noxious, are little known except to naturalists and are undistinguished by any popular names.

It will be sufficient here to define them as Arthropoda for the most part of aquatic habits, having typically two pairs of antenniform appendages in front of the mouth and at least three pairs of post-oral limbs acting as jaws.

Recent observations, however, make it very doubtful whether aquatic Crustacea can hear at all, in the proper sense of the term, and it has been shown that one function, at least, of the so-called otocysts is connected with the equilibration of the body.

There are a few pigeons and aquatic birds, butterflies and beetles.

In order to meet these peculiarities the travelling organs of aquatic and flying animals (whether they be feet, fins, flippers or wings) are made not of rigid but of elastic materials.

The difference in size of the travelling organs of animals becomes very marked when the land animals are contrasted with the aquatic, and the aquatic with the aerial, as in figs.

In the southern and western islands the fauna is restricted mainly to foxes, bats, rats, mice, the sea otter, the penguin and other aquatic birds, and various cetaceans in the surrounding waters.

Thus Drosophyllum occurs only in Portugal and Morocco, Byblis in tropical Australia, and, although Aldrovanda is found in Queensland, in Bengal and in Europe, a wide distribution explained by its aquatic habit, Dionaea is restricted to a few localities in North and South Carolina.

Pinguicula is abundant in the north temperate zone, and ranges down the Andes as far as Patagonia; the 250 species of Utricularia are mostly aquatic, and some are found in all save polar regions; their unimportant congeners, Genlisea and Polypompholix, occur in tropical America and south-western Australia respectively.

Every natural hollow is full of water, around the margin of which long grasses, reeds and other aquatic plants grow in the greatest profusion, often making it difficult to say where the land ends and the water begins.

Although chiefly arboreal, many of the iguanas take readily to the water; and there is at least one species, Amblyrhynchus cristatus, which leads for the most part an aquatic life.

Though they are thus the most aquatic of lizards, Darwin, who studied their habits during his visit to those islands, states that when frightened they will not enter the water.

Aldrovandi in De animalibus insectis (1602) almost contemporaneously distinguished between "terrestrial insects," including woodlice, earthworms and slugs, and "aquatic insects," comprising annelids and starfishes.

His theory is that in the early Cretaceous epoch the animals of the world were mostly aerial, amphibious, aquatic or arboreal; the flora of the land being undeveloped as compared with its present state.

For the purposes of such zoo-geographical divisions, mammals are much better adapted than birds, owing to their much more limited powers of dispersal; most of them (exclusive of the purely aquatic forms, such as seals, whales, dolphins and sea-cows) being unable to cross anything more than a very narrow arm of the sea.

As regards aquatic mammals, the greater number of the Cetacea, or whales and dolphins, have, as might be expected, a very wide distribution in the ocean.

The seals (Pinnipedia) although capable of traversing long reaches of ocean, are less truly aquatic than the last two groups, always resorting to the land or to ice-floes for breeding.

The single genus (Isoetes) contains about fifty, mostly aquatic, species, though a few are amphibious or terrestrial.

In the absence of direct evidence from Palaeobotany, and bearing in mind the modifications associated with adaptation to an aquatic life in other plants, the recognition of any more definite affinity for these heterosporous ferns than that indicated above appears to be inadvisable.

They are also found in some of the semi-terrestrial and purely aquatic Amphipod Crustaceans.

Such renal caecal tubes seem to be readily evolved from either metenteron or proctodaeum when the conditions of the out-wash of nitrogenous waste-products are changed by the transference from aquatic to terrestrial life.

The absence of such renal caeca in Limulus and their presence in the terrestrial Arachnida is precisely on a parallel with their absence in aquatic Crustacea and their presence in the feebly branchiate Amphipoda.

They appear to be serial equivalents (homogenous meromes) of the tracheal gills, which develop in a like position on the abdominal segments of some aquatic Hexapods.

Our general conclusion from a survey of the Arthropoda amounts to this, that whilst Peripatus, the Diplopoda, and the Arachnida represent terrestrial offshoots from successive lower grades of primitive aquatic Arthropoda which are extinct, the Crustacea alone present a fairly full series of representatives leading upwards from unspecialized forms. The latter were not very far removed from the aquatic ancestors (Trilobites) of the Arachnida, but differed essentially from them by the higher specialization of the head.

Of birds there are over loo species, more than one-half being aquatic. In the interior the whistling swan is common, and numerous varieties of ducks are found in the lakes.

Innumerable aquatic birds haunt the banks of the Save, Danube and Drina, and the lower reaches of the Timok and Morava; among them being pelicans, cranes, grey and white herons, and many other kinds of waders, besides wild geese, ducks, rail and snipe.

Forest Park (464 acres), in the southern part of the city, is the largest and most attractive; it contains a good zoological collection, and in its ponds is one of the finest collections in America of lotus plants and Oriental aquatic flora; at its southern entrance is a monument to President McKinley by Philip Martiny.

So far as is known, the production of cocoons is universal among earthworms and the remaining Oligochaeta of aquatic habit.

Some of the species are thoroughly aquatic and have fully webbed toes, others are terrestrial, except during the breeding season, others are adapted for burrowing, by means of the much-enlarged and sharp-edged tubercle at the base of the inner toe, whilst not a few have the tips of the digits dilated into disks by which they are able to climb on trees.

A striking feature is the presence of large, radiating intercellular cavities in the cortex, suggesting an aquatic habit.

A comparison, formerly suggested, with the two forms of leaf in Batrachian Ranunculi has not proved to hold good; the idea of an aquatic habit is contradicted by the anatomical structure, and the hypothesis that the plants were of scandent growth is more probable.

Aquatic plants, especially water-lilies, are abundant and varied; the soil-dry Callitris and Widdringtonia become scarce.

It was not suspected,, or the fact was ignored, that the break between Cretaceous and Tertiary - made so conspicuous by striking changes in the aquatic animals - had little or no importance in botanical history.

The plants contained in the Cromer Forest-bed, of which about 150 species have now been determined, fall mainly into two groups - the forest-trees, and marsh and aquatic plants.

The first category embraces many aquatic newts, the second nearly all the Ecaudata, the third the rest of the Caudata, and the fourth the Apoda.
