The bull trout is a char of the family Salmonidae native to northwestern North America. Historically, S. confluentus has been known as the "Dolly Varden", but was reclassified as a separate species in 1980. Populations of bull trout in the lower 48 states are listed as threatened under the U.S. Endangered Species Act, and bull trout overall are listed as vulnerable to extinction on the IUCN Red List of Threatened Species. The Saskatchewan-Nelson Rivers population in Alberta, Canada is listed as threatened under the Species at Risk Act.
The brook trout is a species of freshwater fish in the char genus Salvelinus of the salmon family Salmonidae native to Eastern North America in the United States and Canada. Two ecological forms of brook trout have been recognized by the US Forest Service. One ecological form is short-lived potamodromous populations in Lake Superior known as coaster trout or coasters. The second ecological form is the long-living predaceous anadromous populations which are found in northern lakes and coastal rivers from Long Island to Hudson Bay, which are referred to as salters. In parts of its range, it is also known as the eastern brook trout, speckled trout, brook char, squaretail, brookie, or mud trout, among others. Adult coaster brook trout are capable of reaching sizes over 2 feet in length and weigh up to 6.8 kg (15 lb), whereas adult salters average between 6 and 15 inches in length and weigh between 0.5 and 2.3 kg. The brook trout is characterized by its distinctive olive-green body with yellow and blue-rimmed red spots, white and black edged orange fins, and dorsal vermiculation. The diet of the brook trout is restrictive to the season and location of the fish, but will typically consist of terrestrial and aquatic insects, fry, crustaceans, zooplankton, and worms.
The Arctic char or Arctic charr is a cold-water fish in the family Salmonidae, native to alpine lakes, as well as Arctic and subarctic coastal waters in the Holarctic.
The Dolly Varden trout is a species of salmonid ray-finned fish native to cold-water tributaries of the Pacific Ocean in Asia and North America. Despite the name "trout", it belongs to the genus Salvelinus (chars), which includes 51 recognized species, the most prominent being the brook, lake and bull trout as well as the Arctic char. Although many populations are semi-anadromous, riverine and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap.
Salvelinus is a genus of salmonid fish often called char or charr; some species are called "trout". Salvelinus is a member of the subfamily Salmoninae within the family Salmonidae. The genus has a northern circumpolar distribution, and most of its members are typically cold-water fish that primarily inhabit fresh waters. Many species also migrate to the sea.

They are found in depths of 550 to 1450 meters near or at the bottom over upper continental slopes.
The slippery dick is a species of wrasse native to shallow, tropical waters of the western Atlantic Ocean.
The fangtooth moray sometimes also known as tiger moray or bird-eye conger is a moray eel of the family Muraenidae found in warmer parts of the eastern Atlantic Ocean, including the Canary Islands, Madeira and various other islands. It entered the Mediterranean Sea from the Atlantic and is now found occasionally in the eastern Basin, from Levantine waters and off Turkey, Greece, Croatia and Sicily.
The spottail shiner or spottail minnow is a small- to medium-sized freshwater minnow. It can be found as far north as Canada and as far south as the Chattahoochee River in Georgia. These shiners live in lakes, rivers, and creeks. They occupy the rocky or sandy shorelines and bottoms of the water. One of the defining features of a spottail shiner is the black spot found at the base of the caudal fin. These shiners generally spawn from late June through July.
Western blacknose dace is a common species of ray-finned fish belonging to the family Cyprinidae and the genus Rhinichthys. Western blacknose dace have tan to dark brown backs, lighter sides, and cream colored undersides. Dark blotches are sporadically scattered across their sides and backs. A distinctive dark colored mid-lateral stripe from the tip of the snout to the caudal peduncle is present. The snout is relatively long and they have a slightly sub-terminal mouth. The stripe is dark brown in females and is a rusty pink color in males during spawning season. The lateral stripe is more pronounced and the caudal spot is present in juveniles. Similar to other species of dace the western blacknose dace give the illusion of having no scales but in actuality the scales are so small they are hard to see. Western blacknose dace are typically 2-3 inches long but can grow to as long as 4 inches. They have a forked tail, single dorsal fin with 8 rays and no spines, a pelvic fin on the abdominal, no adipose fin, and an anal fin with 7 rays and no spines.
Percina maculata, the blackside darter, is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is a widespread inhabitant of streams and rivers in the Mississippi River watershed. Like other darters it prefers rocky riffles and sandy runs, but is tolerant of pools and still water as well. It is one of the 324 fish species found in Tennessee.
Percina phoxocephala, the slenderhead darter, is a species of freshwater ray-finned fish, a darter from the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches. It is found in North America in the central Ohio and Mississippi River basins, to northeastern South Dakota and the Lake Winnebago system in Wisconsin, and as far south as the Red River in eastern Oklahoma and northeast Texas, typically in small to medium size rivers. It is a colorful species, with an average length of 6 to 9 centimeters. Males take on a deeper hue during the breeding season. It feeds on insect larvae and other small invertebrates, and spawns between April and June. It is a common fish with a very wide range and the International Union for Conservation of Nature has classified its conservation status as being of "least concern".
The yellowmouth grouper, also known as the crossband rockfish, grey mannock, hamlet, harlequin rockfish, princess rockfish, rockfish, salmon grouper, salmon rock fish or scamp, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is part of the family Serranidae, which also includes the anthias and sea basses. It is found in the Caribbean and in the tropical waters of the Atlantic Ocean. It is also found in pockets in Brazil. It is a fairly large fish and it gets its name from the yellow around its mouth.

Salvelinus willughbii, also known as the Windermere charr or Willoughby's charr, is a cold-water fish in the family Salmonidae. Its binomial species name commemorates Francis Willughby. They are remnants from the end of the last ice-age, landlocked and isolated in various lakes within Cumbria, England. S. willughbii are a subspecies of Arctic charr that inhabit Lake Windermere, Coniston Water, Wast Water, Ennerdale Water, Buttermere, Crummock Water, and Lowes Water in The Lake District of Cumbria, England.The species has been listed on the IUCN Red List as endangered due to increased water temperatures, decreased levels of oxygen, and overfishing within Lake Windermere.
Salvelinus murta, also known as the Murta char, is a cold-water fish in the family Salmonidae sometimes referenced as a subspecies of Arctic char. The Murta char is one of the few vertebrate species exclusively endemic to Iceland. The species range lies entirely within the lake Þingvallavatn. The Murta Char was originally described by the Icelandic ichthyologist Bjarni Sæmundsson in 1909. According to the most recent IUCN assessment in 2008, there are some piscivorous individual variants displaying non-standard morphology that eat three-spined stickleback although most individuals rely heavily on zooplankton and aquatic insects. The Murta Char is confirmed to live up to 18 years with first spawning usually occurring at 3–6 years of age in October.
