Percina westfalli, the Sooty-banded darter or Westfall's darter is a species of darter (subfamily Etheostomatinae) native to the Southeastern United States. [1] A benthic fish, they typically inhabit streams and smaller rivers over sand or gravel bottoms where they are primarily insectivorous. [2] The species is sympatric with P. crypta within the Apalachicola Basin.

After its initial description the species was later synonymised with P. nigrofasciata, but has since been split and is once again recognised as a full species. [3] There are still many sources that have yet to update their material to accommodate the split.

Range

They occur from the Apalachicola river basin eastwards on the Gulf Slope and from the Savannah river basin south to the St. Johns river basin on the Atlantic Slope. [4] Sources from before this species was split found the former parent taxon, P. nigrofasciata, absent from the Satilla and St. Mary's river systems in Georgia and Florida. [5] [2] Though considered common throughout most of its range, they are thought rare in the Altamaha River. [5]

<i>Percina</i> Genus of fishes

Percina is a genus of small freshwater ray-finned fish, classified within the subfamily Etheostomatinae, part of the family Percidae, which also contains the perches, ruffes and pikeperches from North America. Along with similar fishes in certain other genera, members of Percina are commonly called "darters". More specifically, the genus as a whole is known as roughbelly darters, while certain species of Percina with a pattern of vertical bars on the flanks are called logperches.

<i>Medionidus penicillatus</i> Species of bivalve

Medionidus penicillatus, the gulf moccasinshell, is a rare species of freshwater mussel in the family Unionidae, the river mussels.

<span class="mw-page-title-main">Blackbanded darter</span> Species of fish

The blackbanded 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 native to the river systems of the southeastern United States where it is found in the states of Tennessee, Georgia, Florida, Mississippi, Alabama, and Louisiana. It lives over sandy or gravelly bottoms in smaller rivers and streams and its color varies depending on the different habitats in which it lives. It feeds on small insect larvae and is itself preyed on by larger fish. It spawns between February and June depending on locality. It is generally a common fish throughout most of its range.

The bronze 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 restricted to the Coosa and Tallapoosa River systems in Georgia, Alabama, and southeastern Tennessee in the United States. It feeds on insect larvae and other small invertebrates, and spawns in April and May. It is a common fish within its range and the International Union for Conservation of Nature has classified its conservation status as being of "least concern". However, it is susceptible to environmental disturbance and an ongoing management plan has been put in place to protect its habitat.

The saddleback 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 native to the eastern United States. This darter species is widespread, occurring from the Escambia River drainage west to the Mississippi River basin and as far north as the Wabash River historically. Some populations have been reported in the Tennessee River drainage. The saddleback darter is aptly named as it has 5 saddle-like patterns on its dorsum, with the first occurring near the first dorsal fin and the fifth near the caudal penduncle. Adults can attain a maximum size of about 3 inches or 7.8 centimeters. The saddleback darter typically occurs over sand and gravel runs of creeks and small to medium-sized rivers and is sometimes found in very shallow water. This darter's diet consists of invertebrates such as caddisfly larvae, beetles, mayflies, and stoneflies. The saddleback darter deposits eggs over sand and gravel shoals during the spring. This species has an average lifespan between 2 and 3 years.

The sickle darter is a recently identified 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 closely related to a well-known darter, Percina macrocephala. Discovered in 2007 in the upper Tennessee River drainage, the sickle darter is around 90.5 mm (3.56 in) in length and is a slender bodied, freshwater and benthopelagic fish that most likely feeds on small crayfish and mayflies, since it shares a large mouth and long snout with its sister species. The known distribution of the sickle darter is the upper drainage of the Tennessee River of Tennessee, North Carolina and Virginia. It is distinguished from all other Percina darters except its sister species P. macrocephala by a dark suborbital bar and a black bar subtending a medial black spot on the base of the caudal fin. It stays in mostly rocky, sandy, or silty substrates in clear creeks or small rivers in the Appalachian Mountains. The sickle darter spawns in late winter in gravel shoals. It also has large scales which make it different from macrocephala. It is known to be extirpated from most of its home habitat mainly because of agricultural practices that cause siltation and turbidity which causes most populations of the sickle darter to be widely scattered. But where it is found, it can be observed with regularity. Taking all this into consideration, the sickle darter does not have a formal conservation status under any federal or state law although its closely related species is considered a species of concern by the TWRA. Future management plans should include finding more locations of the sickle darter and decreasing further habitat destruction in known distributions by stating it as a fish of concern by state law.

Percina peltata, the shield 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 endemic to the eastern United States.

<span class="mw-page-title-main">Halloween darter</span> Species of fish

The Halloween darter is a small freshwater fish native to North America. It is found in Georgia and Alabama in the drainage basin of the Apalachicola River, specifically in the Flint River system and the Chattahoochee River system. It prefers shallow, fast-flowing areas with gravel bottoms in small and medium-sized rivers. It was first described in 2008, having not previously been distinguished from the Blackbanded darter (P. nigrofasciata), formerly thought to occur in the same watershed. Blackbanded darter has since been split again with Westfall's darter now recognised from the Apalachicola drainage. The species is somewhat variable, being generally blackish dorsally, with some individuals having indistinct saddle-like barring. Males have orange and dark lateral striping while females have dark stripes and a yellowish-green belly. At a maximum standard length of 101 mm (4 in), males are slightly larger than females, and both sexes develop distinctive orange barring on the edge of the first dorsal fin during the breeding season.
