The California killifish (Fundulus parvipinnis) is a type of killifish (Fundulidae) found along the coast of southern California and Baja California.

Like the other members of the family, California killifish are small, no more than about 11 cm in length. The body is rather thick and oblong in shape, with almost no narrowing of the caudal peduncle, and a squarish tail fin. The pelvic fins are small, while the anal fin is long, with 11-13 rays. They are olive-green above, and a yellowish brown below; during breeding season, the back become dark brown, while the belly and paired fins become bright yellow.

They are coastal fish, occurring in shallow bays, estuaries, marshes, and the lower parts of streams from Morro Bay south to Magdalena Bay in central Baja California. Between Goleta Slough and the Tijuana River they occur almost continuously, the frequency of wetlands being sufficient to allow free movement. They tolerate a wide range of salinities, oxygen levels, and pollution.

The diet consists of a variety of both benthic and planktonic invertebrates, anything from snails to crustaceans to insects, often found by foraging through areas of vegetation flooded by high tides.

This species and the Baja California killifish F. lima are the only members of Fundulus on the west coast of the continent, and are distinct from the rest of the genus, which is limited to the east coast. It has been suggested that they may form a separate genus.

Mummichog Species of fish

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.

<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).

Banded killifish Species of fish

The banded killifish is a North American species of temperate freshwater killifish belonging to the genus Fundulus of the family Fundulidae. Its natural geographic range extends from Newfoundland to South Carolina, and west to Minnesota, including the Great Lakes drainages. This species is the only freshwater killifish found in the northeastern United States. While it is primarily a freshwater species, it can occasionally be found in brackish water.

Big skate Species of cartilaginous fish

The big skate is the largest species of skate in the waters off North America. They are found along the Pacific Coast from Alaska to Baja California, typically from the intertidal zone to a depth of 120 m (390 ft), and feed on benthic invertebrates and small fishes. They are unusual among skates in that their egg cases may contain up to seven eggs each. This species is one of the most commercially important skates off California and is sold for food.

Sawtail grouper Species of fish

The sawtail grouper 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 endemic to the western coasts of Mexico. The sawtail grouper commonly lives on fields of large boulders with gorgonians and black corals.

The plains topminnow is a species of freshwater topminnow found in North America. The fish has a small range within the United States of America which consists of two major populations.

The Baja California killifish is a killifish in the family Fundulidae. It is native to the Baja California Peninsula region of northwestern Mexico. This fish was described by L.L. Vaillant in 1894 with the type locality given as San Ignacio de Caracamande in central Baja California.

Gulf killifish Species of fish

The Gulf killifish is one of the largest members of the genus Fundulus; it is capable of growing up to 18 cm in length, whereas the majority of other Fundulus reach a maximum length of 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.

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

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

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

The longnose killifish is a marine tropical benthopelagic fish of the genus Fundulus and the family Fundulidae. 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

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 mm in total length. Its distribution extends along the U.S. east coast from Massachusetts to Georgia.
