Dolphins don't have gills.

Green around the gills.

We put water over its gills, give it oxygen.

Turtles eat it. It gets in the gills of fish.

You show me a creature with webbed feet and gills somehow water's involved.

I don't know what this kind of stuff will do in their gills.

2 the gills are medial to the operculum, but lateral to the heart.

Now I don't mean extra gills or something something we care about, like aging.

Respiration Like other fish, sharks extract oxygen from seawater as it passes over their gills.

As an example, oysters draw water in over their gills through the beating of cilia.

While doing this, a cloud of sand surrounds the ray and sand spews from its gills.

Near the gills are the eyes, which are poorly developed and buried under skin in the larvae.

Tadpoles are typically herbivorous, feeding mostly on algae, including diatoms filtered from the water through the gills.

Krill can be easily distinguished from other crustaceans such as true shrimp by their externally visible gills.

The olm breathes with external gills that form two branched tufts at the back of the head.

Here the shark pumps blood to its gills via the ventral aorta artery where it branches into afferent brachial arteries.

Hemoglobin in the blood carries oxygen from the respiratory organs (lungs or gills) to the rest of the body (i.e.

While the shark is moving, water passes through the mouth and over the gills in a process known as ram ventilation .

In most fish, the esophagus is extremely short, primarily due to the length of the pharynx (which is associated with the gills).

Those in the oral cavity are used for tasting food, where those near the gills probably sense chemicals in the surrounding water.

However, certain species, like the nurse shark, are capable of pumping water across their gills, allowing them to rest on the ocean bottom.

Uniquely among rays they dig with their snouts in the sand, surrounding themselves in a cloud of sand that spews from their gills.

The ventral aorta delivers blood to the gills where it is oxygenated and flows, through the dorsal aorta, into the rest of the body.

Reoxygenation takes place in the gills and the reoxygenated blood flows into the efferent brachial arteries, which come together to form the dorsal aorta.

Some fish are also known to expel air from their gills here the burp is produced by gas being expelled from the gas bladder.

In fish, the system has only one circuit, with the blood being pumped through the capillaries of the gills and on to the capillaries of the body tissues.

These fish are also able to use this large mouths as a means of propulsion when frightened, they will gulp a large amount of water and expel it through their gills.

In fish the slits are modified to form gills, but in some other chordates they are part of a filter feeding system that extracts particles of food from the water in which the animals live.

In vertebrates, the carbon dioxide travels in the blood from the body's tissues to the skin (e.g., amphibians) or the gills (e.g., fish), from where it dissolves in the water, or to the lungs from where it is exhaled.

They are extremelly useful as they are sessile which means they are closely representative of the environment where they are sampled or placed (caging) , and they are breathing water all along the day, exposing their gills and internal tissues bioaccumulation.

In the juvenile (or tadpole) stage, the circulation is similar to that of a fish the two chambered heart pumps the blood through the gills where it is oxygenated, around the body and back to the heart in a single loop.

The amount of oxygen an animal can absorb is largely determined by the area of its oxygen absorbing surfaces (lungs and gills in the most complex animals the skin in less complex ones) but, the amount needed is determined by its volume, which grows faster than the oxygen absorbing area if an animal s size increases equally in all directions.

The forcible discharge of single spores termed ballistospores involves formation of a small drop of water (Buller's drop), which upon contact with the spore leads to its projectile release with an initial acceleration of more than 10,000 g the net result is that the spore is ejected 0.01 0.02 cm, sufficient distance for it to fall through the gills or pores into the air below.
