WAetobatus laticeps, the Pacific white-spotted eagle ray, is a species of cartilaginous fish in the eagle ray family Myliobatidae. It is found in the tropical East Pacific Ocean, ranging from Baja California to northern Peru, including the Galápagos. Until 2014, it was included in the similar spotted eagle ray, but the two differ in genetics. Following the split, A. narinari is restricted to the Atlantic, while the Indo-Pacific is inhabited by the closely related A. ocellatus.

WThe bat ray is an eagle ray found in muddy or sandy sloughs, estuaries and bays, kelp beds and rocky-bottomed shoreline in the eastern Pacific Ocean, between the Oregon coast and the Gulf of California. It is also found in the area around the Galápagos Islands. The largest specimens can grow to a wingspan of 1.8 m and a mass of 91 kg (201 lb). They more typically range from 9.07–13.61 kg (20.0–30.0 lb). The size of the bat gray is dependent on many factors, such as habitat alterations, different oceanographic and environmental conditions. The sexual maturity size of the female Myliobatis california is often greater than the male one. Bat rays are euryhaline, i.e. they are able to live in environments with a wide range of salinities.
WThe blackchin shiner is an abundant North American species of freshwater fish from the family Cyprinidae. Described by Edward Drinker Cope in 1865, it is not a well-known species. It is a close relative of the blacknose shiner. Chiefly occurring now in the Great Lakes and occasionally in upper Mississippi River drainages, the blackchin once ranged commonly as far south as Illinois and Ohio. This fish resides over sandy bottoms in cool waters that provide a lot of cover for the small minnow. Omnivorous, it eats worms and small arthropods as well as plant material. Blackchin shiners are unique because of their anatomical features, such as the black coloring, the incomplete lateral line, and a distinctive dental arrangement.
WLabidesthes sicculus, also known as the Brook silverside is a North American species of Neotropical silverside. The brook silverside lives in slow moving rivers and lakes from the Great Lakes to the Mississippi Basin and Gulf Coastal Plains. The brook silverside survives best in clear water with aquatic vegetation. L. sicculus feeds on a diet of copepods, insect larvae, and winged insects. The spawning season of the brook silverside occurs during the spring and early summer. The survival of freshwater fishes such as the brook silverside is increasingly threatened. In order to ensure survival of the brook silverside, turbidity of natural habitats should be monitored.

This fish grows to a length of 5.8 centimetres (2.3 in) SL and can be found in the aquarium trade.
WThe mimic shiner is a species of North American cyprinid freshwater fish in the genus Notropis. The genus Notropis is commonly known as the eastern shiners. It is native to areas of the Hudson Bay drainage, Great Lakes drainage, much of the Mississippi River basin including areas of Tennessee, Virginia, North Carolina, and regions of the Gulf of Mexico extending from Mobile Bay to the drainage of Texas. However, this particular species can be found in other places such as the Atlantic Coast drainage in Connecticut and Housatonic rivers. This genus is usually characterized by almost all having a complete lateral line, 8 dorsal fin rays, a premaxillae protactile, and a silvery or speckled peritoneum. As the common name indicates, this species is difficult to classify in the wild because it looks similar to many other shiners. In fact, some even hypothesize that this species is actually a complexity of many cryptic species. While this is the case, it is important to take more caution to not misidentify this species and to understand its impact on introduced areas.
WThe painted goby is a small goby of Western European waters from Trondheim Fjord to Spain, the Canary Islands and is sometimes reported in the Mediterranean Sea. Also mentioned in the Black Sea.

It is threatened by habitat loss through palm oil plantations, other agriculture, deforestation, and urban development.

WThe silver shiner is a species of ray-finned fish in the genus Notropis. It is found in the United States and Canada where it inhabits much of the Ohio River basin south to northern Georgia in the Tennessee River drainage. It also found in western Lake Erie tributaries and the Grand River system in Ontario. Though visually very similar to the emerald shiner, which occupies a similar range, it can be distinguished by the presence of two dark crescents between its nostrils, on the top of the head.

WSilverjaw minnows are part of the family Cyprinidae, which includes carps and minnows. With over 300 known species, there are more species of minnows native to North America's fresh waters than any other fish. Minnows can be hard to distinguish because many look alike. All minnows have one dorsal fin, ventral fins near the anus, a lateral line system, and smooth, round cycloid scales. Their jaws lack teeth, but they have one to three rows of pharyngeal teeth to grind food. Defining physical characteristics such as the number and type of fin rays, type of scales, and pattern of pharyngeal teeth are used to distinguish minnows.
WThe swallowtail shiner is a North American species of freshwater fish in the family Cyprinidae. It has a slender and long body of about 40–55 mm. The shiner has a pale yellow back with a blue stripe on its silver side. It also has a silvery white belly. Its fins are yellowish and it has a dorsal fin originating above the back half of the pelvic fin base and a tail fin with a black spot at its base. Its snout is either slightly pointed or slightly rounded. The swallowtail shiner lives in warm creeks and in river pools. It is known to live in Virginia in the New River system and near the Atlantic slope. It is often found near plants. The shiner eats insects, worms, mites, microcrustaceans, and algae. Juvenile shiners mature after a year and spawn from mid-May to July when the water reaches a temperature of 25.6 °C. Fecundity is unknown in this species and it breeds well in aquariums. It is similar to the closely related Cape Fear shiner and sand shiner.
