The Waccamaw killifish (Fundulus waccamensis) is a species of fish in the family Fundulidae. It is endemic to Lake Waccamaw, a lake in North Carolina, United States, and its tributaries. [1]

Contents

Distribution and habitat

Reliable reports of this species' occurrence are from only a single location, Lake Waccamaw and its tributaries, in Columbus County, North Carolina. While restricted in range, the fish is common there and total population may exceed 1 million. It is found in mid-level or near-surface waters over sandy bottoms in open waters or closer to vegetation around shores, and in winter may venture into surrounding swamps and canals. [1] This species has been recorded in Lake Phelps in Washington County, North Carolina where it was most likely introduced by anglers using it as bait. [2]

Conservation

While there are no known specific threats to the Waccamaw killifish, it is currently classified as vulnerable by the IUCN because of its restriction to a single location. [1]

Lake Waccamaw is a town in Columbus County, North Carolina, United States. The 2010 census population was 1,480. Originally home to Native Americans, Europeans later colonized Lake Waccamaw in the 18th century. The Europeans built naval stores and the discovery of turpentine oil led to the Wilmington-Manchester railroad track being created. A shingle company was later converted to a lumber company. In 1910, a group of townspeople created the Waccamaw Club.

The mummichog is a small killifish found along the Atlantic coast of the United States and Canada. Also known as Atlantic killifish, mummies, gudgeons, and mud minnows, these fish inhabit brackish and coastal waters including estuaries and salt marshes. The species is noted for its hardiness and ability to tolerate highly variable salinity, temperature fluctuations from 6 to 35 °C, very low oxygen levels, and heavily polluted ecosystems. As a result, the mummichog is a popular research subject in embryological, physiological, and toxicological studies. It is also the first fish ever sent to space, aboard Skylab in 1973.

<span class="mw-page-title-main">Killifish</span> Any of various oviparous cyprinodontiform fish

A killifish is any of various oviparous (egg-laying) cyprinodontiform fish, including families Aplocheilidae, Cyprinodontidae, Fundulidae, Profundulidae and Valenciidae. All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as Kryptolebias marmoratus, can additionally survive out of the water for several weeks. Most killies are small fish, from 2.5 to 5 centimetres, with the largest species growing to just under 15 centimetres (6 in).

Lake Waccamaw is a fresh water lake located in Columbus County in North Carolina. It is the largest of the natural Carolina Bay lakes. Although bay trees are present within many Carolina Bays, the term "bay" does not refer to the trees but comes instead from an early science publication by Glenn (1895), who used the word "bay" to refer to these features near the town of Darlington, South Carolina. Lake Waccamaw is fed by four creeks: First, Second, Third, and Big creeks. The outlet forms the Waccamaw River which flows south-southwest to empty into the Atlantic Ocean near Georgetown, South Carolina

<i>Fundulus</i> Genus of fishes

Fundulus is a genus of ray-finned fishes in the superfamily Funduloidea, family Fundulidae. It belongs to the order of toothcarps (Cyprinodontiformes), and therein the large suborder Cyprinodontoidei. Most of its closest living relatives are egg-laying, with the notable exception of the splitfin livebearers (Goodeidae).

<span class="mw-page-title-main">Gulf killifish</span> Species of fish

The Gulf killifish is one of the largest members of the genus Fundulus; it is capable of growing up to 7 inches (18 cm) in length, whereas the majority of other Fundulus reach a maximum length of 4 inches (10 cm). Therefore, F. grandis is among the largest minnows preyed upon by many sport fish, such as flounder, speckled trout, and red drum. Fundulus derives from the Latin meaning "bottom," and grandis means "large". The Gulf killifish is native to the Gulf of Mexico from Texas to Florida and the eastern coast of Florida and the Caribbean Sea in the Atlantic Ocean. Threats to the survival of the Gulf killifish include extreme changes in salinity, changes in temperatures, and toxic events such as the hypoxic dead zone in Louisiana and the Deepwater Horizon oil spill. The Gulf killifish is currently being used to test the effects of oil and oil dispersants on the physiology of marine species affected by these substances. This is significant to conservation biology, because with the continued extraction of oil and other natural resources from North American waters, it has become increasingly important to understand the risks and consequences in worst-case scenarios, such as the Deepwater Horizon oil spill, and the lasting effects on the marine ecosystem.

It is endemic to the western Atlantic Ocean, ranging from along the coast of the Gulf of Mexico from the Florida Keys to Tampico in Mexico. It can grow up to 12 centimeters in length. The body is rounded, elongate, and olive to silver colored with dark vertical stripes. It can be distinguished from other killifish by its long snout and a dark spot on last vertical bar. This species requires to be allocated a new binomial as Fundulus similis is preoccupied by a junior synonym of Fundulus majalis, the name having been given to a Gulf of Mexico population of that species.

<i>Fundulus luciae</i> Species of fish

Fundulus luciae, the spotfin killifish, is a member of the genus Fundulus. This hardy fish is notable for spending its entire life in sporadically flooded salt marsh habitat, sheltering in shallow pools, puddles, and small tidal rivulets. It closely resembles the mummichog in shape and coloration, but the two species can be distinguished by dorsal fin ray count: 8–9 in the spotfin versus 11–12 in the mummichog. Additionally, the dorsal fin of F. luciae originates farther back, and slightly behind the anal fin origin; in the mummichog, the dorsal fin begins anteriorly to the anal fin origin. The spotfin killifish is named for the pronounced ocellus found on the posterior dorsal fin of adult males. It is a small fish, seldom attaining 50 millimetres (2.0 in) in total length. Its distribution extends along the U.S. east coast from Massachusetts to Georgia.
