Justification:
This widely distributed species can be common and abundant in parts of its range where it occurs over shallow coral or rocky reef. Coral reef habitat has declined by 59% over the past 41 years. Its generation length is short and three generations is inferred as no more than 10 years. It has been documented as susceptible to predation by the invasive lionfish, which now occurs throughout its entire range. An overall 65% decline in prey biomass was directly observed over a period of two years in the Bahamas. However, species-specific declines are not available at this time. Based on this information, a suspected population decline of >30% is projected to occur over the next ten years due to predation by the invasive lionfish. Therefore, it is listed as VU A3ce. We recommend improved monitoring on the effects of habitat degradation and predation by the invasive lionfish.

Geographic Range [top]

Range Description:Coryphopterus eidolon is distributed in the western Atlantic from the Bahamas, in the Gulf of Mexico from the Florida Keys to central Florida (Venice), the Flower Garden Banks, and from Campeche, Mexico along the northern Yucatan to northwestern Cuba, and throughout the Caribbean Sea (Robins and Ray 1986, Feitoza et al. 2005, R. Robertson pers. comm. 2014).

Population [top]

Population:This species can be common to abundant. It is reported as abundant in Belize (Baldwin et al. 2009). It was relatively uncommon during surveys in the Mona Passage (Dennis et al. 2005) and uncommon over shelf-edge deep reefs off Brazil (Feitoza et al. 2005).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Coryphopterus eidolon occurs in coral and/or limestone areas over a substrate of fine white coral sand and inhabits reefs deeper than six metres (Böhlke and Robins 1960). It is a benthic spawner. Fishes of this genus are sequential protogynous hermaphrodites (Thacker and Cole 2002). An average of 1734 ± 716 eggs are deposited on a hard substrate by the female and fertilized by the male. Courtship and spawning behaviour in captivity have been described (Kramer et al. 2009). Proxy life history data based on a study of Coryphopterus kuna: Larvae settle around 7-9 mm SL, adults mature at 10–11 mm SL and then only attain about 17 mm SL. It has a 60-day pelagic larval life and matures rapidly. They are sexually active in as few as three weeks and live for about two months after settlement. This is the first reported fish in which the pelagic larval duration is generally longer than the post-settlement lifespan, which indicates that C. kuna may represent the extreme of a bipartite life-history strategy: a relatively slow-growing pelagic larval stage, often with delayed metamorphosis, in combination with a rapidly maturing, high-mortality adult stage (Victor et al. 2010). Based on this information, it is inferred that three generation lengths are almost certainly no more than ten years.

Threats [top]

Major Threat(s): Coryphopterus eidolon has been identified as a prey item of the invasive Lionfish in the Bahamas and Mexican Caribbean and likely in the remainder of its range (Morris and Akins 2009, Green et al. 2012, Valdez-Moreno et al. 2012, Green and Cote 2014). This species is easily targeted by the lionfish given its small, shallow body and demersal habits (Green and Cote 2014). Due to the lionfish's ability to consume a variety of fishes smaller than 15 cm, both adults and juveniles of this species are likely consumed. In the Bahamas, a 65% decline in lionfish prey biomass over a period of two years was observed (species-specific data are not available at this time) (Green et al. 2012). Between 1970-2011 (41 years), an overall 59% decline in coral cover was directly observed in the Caribbean (Jackson et al. 2014).
