Mata Mata
Chelus fimbriata
The mata mata, mata-mata, or matamata is a South American species of freshwater turtle found in the Amazon basin and river system of the eastern Guianas. It was formerly believed to also occur in the Orinoco basin, western Guianas and upper Rio Negro–Branco system, but in 2020 these populations were found to belong to a separate species, Chelus orinocensis. Subsequently, some authorities have modified the common name of Chelus fimbriata to Amazon mata mata. These two are the only extant species in the genus Chelus.

Softshell Turtle
Trionychidae
Trionychidae is a family of turtles, commonly known as softshell turtles or simply softshells. The family was described by Leopold Fitzinger in 1826. Softshells include some of the world's largest freshwater turtles, though many can adapt to living in highly brackish waters. Members of this family occur in Africa, Asia, and North America, with extinct species known from Australia. Most species have traditionally been included in the genus Trionyx, but the vast majority have since been moved to other genera. Among these are the North American Apalone softshells that were placed in Trionyx until 1987.

Leatherback Sea Turtle
Dermochelys coriacea
The leatherback sea turtle, sometimes called the lute turtle, leathery turtle or simply the luth, is the largest of all living turtles and the heaviest non-crocodilian reptile, reaching lengths of up to 2.7 metres and weights of 500 kilograms (1,100 lb). It is the only living species in the genus Dermochelys and family Dermochelyidae. It can easily be differentiated from other modern sea turtles by its lack of a bony shell; instead, its carapace is covered by oily flesh and flexible, leather-like skin, for which it is named. Leatherback turtles have a global range, although there are multiple distinct subpopulations. The species as a whole is considered vulnerable, and some of its subpopulations are critically endangered.

Green Sea Turtle
Chelonia mydas
The green sea turtle, also known as the green turtle, black sea turtle, and Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, due to its diet strictly being seagrass, not to the color of its carapace, which is olive to black.

Loggerhead Sea Turtle
Caretta caretta
The loggerhead sea turtle, loggerhead turtle or loggerhead, is a species of sea turtle distributed throughout the world. It is a marine reptile, belonging to the family Cheloniidae. The average loggerhead measures around 90 cm (35 in) in carapace length when fully grown. The adult loggerhead sea turtle weighs approximately 135 kg (298 lb), with the largest specimens weighing about 200 kg (440 lb). The skin ranges from yellow to brown in color, and the shell is typically reddish brown. No external differences in sex are seen until the turtle becomes an adult, the most obvious difference being the adult males have thicker tails and shorter plastrons than the females.

Kemps Ridley Sea Turtle
Lepidochelys kempii
Kemp's ridley sea turtle, also called commonly the Atlantic ridley sea turtle, Kemp's ridley turtle, and Kemp's ridley, is a species of turtle in the family Cheloniidae. L. kempii is the rarest species of sea turtle and is the world's most endangered species of sea turtle as well as the smallest. It is one of two living species in the genus Lepidochelys. The species L. kempii primarily occupies habitat around the Gulf of Mexico, though its migrations into the Atlantic Ocean are being affected by rising temperatures. Rising sea temperatures expand this species range, leaving them vulnerable to cold-shocking events when weather changes. Kemp's ridley sea turtle is listed as endangered under the Endangered Species Act (ESA), and conservation efforts are attempting to rebuild population numbers. Human activity, including habitat destruction, climate change, and oil spills, threaten populations.

Olive Ridley Sea Turtle
Lepidochelys olivacea
The olive ridley sea turtle, also known commonly as the Pacific ridley sea turtle, is a species of turtle in the family Cheloniidae. The species is the second-smallest and most abundant of all sea turtles found in the world. L. olivacea is found in warm and tropical waters, primarily in the Pacific and Indian Oceans, but also in the warm waters of the Atlantic Ocean.

Flatback Sea Turtle
Natator depressus
The Australian flatback sea turtle is a species of sea turtle in the family Cheloniidae. The species is endemic to the sandy beaches and shallow coastal waters of the Australian continental shelf. This turtle gets its common name from the fact that its shell has a flattened, lower dome than the other sea turtles. It can be olive green to grey with a cream underside. It averages from 76 to 96 cm in carapace length and can weigh from 70 to 90 kg. The hatchlings are larger than other sea turtle hatchlings when they hatch and emerge from their nests.

Red Cherry Shrimp
Neocaridina davidi var. Red
Neocaridina davidi, also known as the cherry shrimp, is a freshwater shrimp native to Taiwan, east of China, the Korean Peninsula, and Vietnam, that is sold globally in the aquatic pet trade. They are omnivores, and their natural habitat in these regions include inland water bodies such as lakes, ponds, rivers, and streams. N. davidi is also able to tolerate a wide range of environmental conditions, and as a result of this is also becoming invasive in thermally polluted waterways of Japan, the United States, Poland, and Germany. It is thought that the release of captive shrimp has led to their presence in these environments. Their natural coloration, or wild type, is a mottled brown, but N. davidi has been selectively bred to produce a diverse array of color morphs including red, orange, yellow, green, blue, violet, white, clear, and more. The popularity of the red morph has led to N. davidi also being known as "cherry shrimp". N. davidi do not have a distinct larval stage, reach maturity in 30 days, and may live 1–2 years. At maturity, the shrimp are approximately 3–4 cm in length.
