[67] Many different factors go into this behavior of pit spawning, including female choice of the male and pit size, as well as the male defense of the pits once they ...
Red muscles are used for sustained activity such as cruising at slow speeds on ocean migrations. White muscles are used for bursts of activity, such as jumping or sudden bursts of speed for catching prey. [45] Mostly fish have white muscles, but the muscles of some fishes, such as scombroids and salmonids, range from pink to
The esophagus is a flexible tube that goes from the mouth to the stomach. The stomach is connected to the intestine via the pyloric sphincter. [7] The intestines of perch consist of the small intestine and large intestine; the intestines have many pyloric caeca and a spiral value, the small intestine consists of a part called the duodenum.
This damage disrupts stomach muscle functions by interfering with normal nerve-to-stomach communication pathways. 2. Post-surgical complications: Surgeries involving the stomach or intestines can ...
This is the secretory part of the stomach. Then the food passes into the gizzard (also known as the muscular stomach or ventriculus). The gizzard can grind the food with previously swallowed grit and pass it back to the true stomach, and vice versa. In layman's terms, the gizzard 'chews' the food for the bird because it does not have teeth to ...
One study examining the stomach contents of threadfin anglerfish off the Pacific coast of Central America found these fish primarily ate two categories of benthic prey: crustaceans and teleost fish. The most frequent prey were pandalid shrimp . 52% of the stomachs examined were empty, supporting the observations that anglerfish are low energy ...

In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in living fish.
