Semicossyphus darwini is a species of ray-finned fish native to the tropical eastern Pacific Ocean. Common names include the Chilean sheepshead wrasse,[ citation needed ] the goldspot sheepshead or the Galapagos sheepshead wrasse. [1]
This is a large wrasse, with a maximum length of 70 cm (28 in). The dorsal fin has twelve spines and ten soft rays while the anal fin has three spines and twelve soft rays. [3]
S. darwini is native to the tropical eastern Pacific Ocean. Its range includes the Galápagos Islands and on the coast of South America, extends from Ecuador southward through Peru to northern Chile. It is normally found among seaweed, including deep-water kelp forests, and its depth range is from 3 to 100 m (10 to 330 ft). [1]
The strong sharp teeth provide evidence of its diet as a benthic predator, and this is confirmed by the stomach contents which include fragments of shells and other coarse calcareous debris as well as detritus. [3] Other large carnivorous fish dwelling in the kelp forest include the Peruvian morwong (Cheilodactylus variegatus), the Chilean sandperch Pinguipes chilensis , the sea chub Graus nigra , and the cabrilla (Sebastes oculatus). [4] These fish are preyed on by the marine otter (Lutra felina) and the South American sea lion (Otaria flavescens). [4]
S. darwini is caught for food throughout its range and is fished commercially in the Galápagos Islands. It is a large, and probably a slow-growing, fish which makes it vulnerable to over exploitation. There was a decline of 80% in the Galapagos populations during the 1997–1998 El Niño event, but the fish stock recovered in the following year, making it likely that the fish had moved to deeper water during the adverse conditions. The International Union for Conservation of Nature considers that there is not enough evidence to assess the conservation status of this fish and has rated it as "data deficient". [1]
The halfmoon, also known as the blue perch, is a species of marine ray-finned fish, a sea chub from the subfamily Scorpidinae, part of the family Kyphosidae. It is native to the coasts of the eastern Pacific Ocean off western North America. It is fished for using hook and line and it is a desirable food fish.
The 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 ray is dependent on many factors, such as habitat alterations, different oceanographic and environmental conditions. Bat rays have one to three venomous barbed spines at the base of its tail. Some bat rays are solitary while others form schools numbering in the thousands.
Paralabrax clathratus, the kelp bass, bull bass or calico bass, is a species of marine ray-finned fish, a sea bass from the subfamily Serraninae, classified as part of the family Serranidae which includes the groupers and anthias. It is found in the eastern North Pacific Ocean where it is an important species for both recreational and commercial fisheries.
Semicossyphus is a genus of wrasses native to the Pacific Ocean.
The red-lipped batfish or Galapagos batfish is a fish of unusual morphology found around the Galapagos Islands and off Peru at depths of 3 to 76 m. Red-lipped batfish are closely related to rosy-lipped batfish, which are found near Cocos Island off the Pacific coast of Costa Rica. This fish is mainly known for its bright red lips. Batfish are not good swimmers; they use their highly adapted pectoral, pelvic and anal fins to "walk" on the ocean floor. When the batfish reaches maturity, its dorsal fin becomes a single spine-like projection.
Cephalopholis panamensis, the Pacific graysby or Panama graysby, is a species of marine ray-finned fish, a grouper from the subfamily Epinephelinae which is in the family Serranidae which also includes the anthias and sea basses. It is found in the Eastern Pacific Ocean.
Scorpaena afuerae, the Peruvian scorpionfish, is a species of marine ray-finned fish belonging to the family Scorpaenidae, the scorpionfishes. This species is found in the eastern Pacific Ocean.
The sixbar wrasse or six-banded wrasse is a species of wrasse in the family Labridae, native to the Indian Ocean and the western Pacific Ocean. It is an inhabitant of reef environments at depths from the surface down to 15 m (50 ft). This species can grow to 20 cm (8 in) in total length, though most individuals do not exceed 15 cm (6 in). It is of minor importance to local commercial fisheries and can also be found in the aquarium trade.
