In both these species the gills distinctly touch and grow on to the stem.

Gills fused to the mantle.

Fish have gills to get the oxygen out of the water.

A remarkable point in the Plecoptera is the presence in some forms (Pteronarcys) of small branching gills on the three thoracic and the front abdominal segments.

The gills are thus metamerically repeated; there may be from four to eighty pairs, but there is these, and all round the animal, is the mantle-skirt.

There may be from one to nine gills between the genital and renal pores.

The venous blood is conducted from the tissues to a large sinus on either side above the pallial groove, and from this sinus passes to the gills by an afferent vessel in each gill on the internal or pedal margin of the axis.

These gills are simple folds or laminae of the body wall.

There is a heart in the pericardium consisting of a median ventricle attached, except in Neomenia, to the dorsal wall of the pericardium, and in Neomenia a pair of auricular ducts returning blood from the gills to the ventricle.

Slender, tapering behind, with subventral cloacal orifice; thin cuticle without papillae; flattened spicules; no gills.

Short, truncate in front and behind; cloacal orifice transverse; gills present; rather thin cuticle; no radula.

Short and truncated in front; thick cuticle, often without papillae; gills and 7 radula present.

Running down into the stem from the cap are a number of shallow thick gills.

Here we have the cushion-like type (stroma) of Nectria and many Pyrenomycetes, the clavate "receptacle" of Clavaria, &c., passing into the complex forms met with in Sparassis, Xylaria, Polyporei, and Agaricini, &c. In these cases the compound sporophore is often termed the hymenophore, and its various parts demand special names (pileus, stipes, gills, po--es, &c.) to denote peculiarities of distribution of the hymenium owlthe surface.

The majority of heads, gills or throats, sides or flanks, paws and pieces of skins cut up in the fur workshops of Great Britain, America and France, weighing many tons, are chiefly exported to Leipzig, and made up in neighbouring countries and Greece, where labour can be obtained at an alarmingly low rate.

Sable gills, the strongest fur suited for ladies' linings, is taken as the standard.

It seemed impossible to admit that an animal which lives for years without losing its gills, and is able to propagate in that state, could be anything but a perfect form.

These are the external gills, through which the animal breathes the oxygen dissolved in the water.

The animal leaves the water after completing its metamorphosis, the last stage of which is marked by the loss of the gills.

But a year later, the second generation having reached sexual maturity, new broods were produced, and out of these some individuals lost their gills and dorsal crest, developed movable eyelids, changed their dentition, and assumed yellow spots, - in fact, took on all the characters of Amblystoma tigrinum.

The heart and pericardial chamber in the oyster lie along the anterior face of the adductor muscle, almost perpendicular to the direction of the gills, with which in Anodon they are parallel.

All the cavities of a side are ultimately in communication with an efferent duct opening on the surface of the body a little above the line of attachment of the gills.

After escaping from the genital aperture they find their way into the infra-branchial part of the mantle cavity of the parent, probably by passing through the suprabranchial chamber to the posterior extremity of the gills, and then being conducted by the inhalent current caused by the cilia of the gills into the infra-branchial chamber.

Gills or branchiae may be developed by parts of an appendage becoming thin-walled and vascular and either expanded into a thin lamella or ramified.

In many of the smaller Entomostraca (Copepoda and most Ostracoda) no special gills are present, and respiration is carried on by the general surface of the body and limbs.

In the primitive Malacostraca the gills were probably, as in the Phyllopoda and in Nebalia, the modified epipodites of the thoracic limbs, and this is the condition found in some Schizopoda.

In the Amphipoda, the gills though arising from the inner side of the bases of the thoracic legs are probably also epipodial in nature.

The gills are inserted at the base of the thoracic limbs, and lie within a pair of branchial chambers covered by the carapace.

The Stenopidea, another primitive group, differing from the Penaeidea in the character of the gills,, appear in the Trias and Jurassic. The Caridea or true prawns and shrimps appear later, in the Upper Jurassic, some of them presenting primitive characteristics in the retention of swimming exopodites on the walking-legs.

They are separated from fishes and batrachians (Pisces and Batrachians) on the one hand, and agree with reptiles, and birds (Reptilia and A y es) on the other, in the possession during intra-uterine life of the membranous vascular structures respectively known as the amnion and the allantois, and likewise in the absence at this or any other period of external gills.

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.

When the facile tendency of Arthropoda to develop tracheal air-tubes is admitted, it becomes probable that the tracheae of Hexapods do not all belong to one original system, but may be accounted for by new developments within the group. Whether the primitive tracheal system of Hexapoda was a closed one or open by serial stigmata in every somite remains at present doubtful, but the intimate relation of the system to the wings and tracheal gills cannot be overlooked.

Some of the forms breathe by gills throughout their existence, and were formerly regarded as establishing a passage from the fishes to the air-breathing batrachians.

One of the most startling discoveries of the decade 1890-1900 was the fact that a number of forms are devoid of both gills and lungs, and breathe merely by the skin and the buccal mucose membrane (20).

Although the lungs are present in such forms as preserve the gills throughout life, it is highly remarkable that quite a number of abranchiate salamanders, belonging mostly to the subfamilies Desmognathinae and Plethodontinae, are devoid of lungs and breathe entirely by the skin and by the bucco-pharyngeal mucose membrane (20).

In the Caudata, external gills (three on each side) persist until the close of the metamorphosis, whilst in the Apoda and Ecaudata they exist only during the earlier periods, being afterwards replaced by internal gills.

The first are truly aquatic and retain the method of respiration of their marine ancestors, gills.

Often their gills collapse and their swim bladder can rupture due to the sudden change in pressure on their bodies.

The Gills report this worked for a while, and Balfour Beatty complied and had white boiler suits for their staff.

Decurrent gills characteristic of many Clitocybe species and the decurrent gills characteristic of many Clitocybe species and the decurrent vein-like folds of Cantharellus cibarius are also easily recognized.

Wednesday, August 07, 2002 Gills sign striker Sidibe BBC Online Gillingham have signed former Swansea striker Mamady Sidibe on a three-year contract.

They then produce mucus which clogs there gills causing them to die.

Their bodies are covered in scales and, like sharks, they use gills to get oxygen from water.

On emerging from the egg, the tadpoles have feathery external gills.

The larvae have external gills, which absorb oxygen directly from the water.

Whole fish should have clear, bright eyes and bright red gills.

All these specimens had brown gills as shown in the photographs.

Also occurring in flat oysters, where the eggs are incubated on the gills.

Water is expelled through the gills creating a vacuum, which sucks the unsuspecting prey in to its doom.
