I got you Electric eels have three sets of internal organs that produce electricity. The organs are made up of special cells called "electrocytes." Electric eels can create both low and high voltage charges with their electrocytes. Electric eels generate their electric shocks much like a battery. Like the stacked plates of a battery, the stacked electric cells can generate an electrical shock of 500 volts and 1 ampere. the brain sends a signal through the nervous system to the electrocytes. This opens the ion channels, allowing sodium to flow through, reversing the polarity momentarily. By causing a sudden difference in electric potential, it generates an electric current in a manner similar to a battery, in which stacked plates each produce an electric potential difference.

When salmon return to their natal streams to spawn, they stop eating and put all their energy into reaching their spawning grounds to reproduce," the U.S. Fish and Wildlife Service posted on Tuesday. "As a result, their bodies begin to shut down, turning them into spooky "zombiefish." This Jekyll and Hyde transformation involves their silver flesh blushing to red, loss of body fat, contraction of their stomach and the deterioration of their internal organs, according to a 2018 government report. Male Pacific salmon even "grow fearsome teeth and hooked upper jaws that they use against each other," the report says.

The walrus has a streamlined body that makes it easy to swim and conserve heat. Because walruses have a small surface-to-volume ratio, along with few protruding body parts, they lose little heat in the cold Arctic weather. Meanwhile, walrus forelimbs and hindlimbs are sleek and webbed, like oars. This means walruses can swim up to 35 kph (22 mph) if startled. On land, the walrus uses its hind limbs to get around, but it cannot use them to stand up. Instead, the walrus uses its limbs to thrust its body forward in small lunges while hardly getting off the ground. And walrus blubber, which can be up to 15 cm (6 inches) thick, acts as a cushion when bouncing around the ice and other hard surfaces.

Pearl perch are pretty, silvery coloured fish with large eyes and several brown longitudinal scale rows that are particularly prominent in juveniles. They are so named because they have a very prominent grey/blue coloured bone (the supraclavical bone) that extends out on each side of the upper rear of the operculum. These bones have a thin layer of skin covering them, which when removed reveals the "pearl" in the form of the bone beneath, which is a brilliant pearly white. In contrast, they also have a faint "false eye" spot at the base of the rear of the dorsal fin, while inside the large mouth is often completely black. Another interesting feature is at night some anglers have reported the inside of the mouth to appear slightly luminescent. This might be due to them feeding on salps or other bioluminescent prey at those times. Most of the time pearlies are voracious predators of smaller fish and invertebrates such as squid.

The Gulf states (Texas, Louisiana, Mississippi, Alabama and West Florida) produce 244 million pounds of shrimp per year. Shrimp production is extremely important to local economies in the Gulf South region – providing thousands of jobs and it is a large source of revenue. The average American consumes 4.0 lbs. of shrimp annually. Comparatively, this is out of 15.5 pounds of seafood people in the United States eat each year. Shrimp consumption is followed by salmon (2.3 pounds) and canned tuna (2.3 pounds).

The evolution of the gar as a group dates back more than 100 million years in the fossil record. Modern gars still retain many "ancient" characteristics, including the ability to breathe in both air and water. The name "gar" is based on an Anglo-Saxon term that means spike or lance. Unfortunately, this species has earned an unfavorable reputation in its native habitat as a trash fish. On the mistaken belief that it damages nets and eats game fish, people hunted this species mercilessly in the 20th century. Once this misconception was finally corrected, the number of alligator gar rebounded back toward previous levels

Ladyfish, also called Ten-pounder, (Elops saurus), primarily tropical coastal marine fish of the family Elopidae (order Elopiformes), related to the tarpon and bonefish. The ladyfish is slender and pikelike in form and covered with fine silver scales; there are grooves into which the dorsal and anal fins can be depressed. A predatory fish, the ladyfish has small, sharp teeth and a bony throat plate between its mandibles. It ranges in length up to 90 cm (35 inches) and may weigh up to 13.6 kg (30 pounds). The young are transparent and eellike. You can find ladyfish towards the west of the North Atlantic Ocean, right from Cape Cod, in the Caribbean Sea, the Gulf of Mexico, and towards southern Brazil. They are also found in the waters near Bermuda and south of North Carolina. In a few instances, ladyfish have been spotted in both the Indian and western Pacific oceans too.

Atlantic bonito live in large schools numbering in the thousands. These large schools feed on the water's surface, pursuing their prey and sometimes leaping over the water's surface in the process. This attracts the interest of seabirds searching for food, making it easier for anglers to spot this species. In addition, tuna anglers sometimes catch Atlantic bonito when trolling for the larger games with pound nets.

The Royal Gramma is a type of saltwater fish that is found around the reefs of the western part of the Atlantic Ocean. Royal Grammas are shoaling fish, who are known to live in a group of many individuals. They do, however, require a lot of space. These fish can behave quite aggressively to each other and even break out in territorial battles, but they are extremely peaceful with other species of fish.

Wahoo have silvery colored scales with a dark, blue-green colored back. Its sides, or flanks, have light blue stripes or barring. People often mistake this species for a barracuda for this reason. Adults typically reach about five or six feet long, but exceptionally large individuals can surpass eight feet in length. People in Hawaii call this species of fish "ono." The word roughly translates to "good to eat." and Ironically enough, the common name of this species also came from the Hawaiian Islands. When Europeans first encountered the islands of Hawaii, they often misspelled Oahu as "Wahoo." This misunderstanding led to the European term for this species.
