The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Chromileptes altivelis (Valenciennes in Cuvier and Valenciennes, 1828)

Common name: panther grouper

Synonyms and Other Names: barrimundi cod, humpback rockcod, humpback grouper, mouse grouper, high-finned grouper. Original combination: Serranus altivelis. No synonyms.

Taxonomy: available through www.itis.govITIS logo

Identification: Commonly misspelled as Cromileptes.

The genus Chromileptes contains only one species, the panther grouper Chromileptes altivelis. The body is distinctly spotted (dark spots on a light background). The head profile is unique amongst the groupers, as it is depressed anteriorly and elevated posteriorly, rising sharply at the nape. Pectoral and caudal fins rounded. Dorsal fin X (17-19), anal fin III (9-10), pectoral rays 17-18 (Heemstra and Randall 1993; Randall et al. 1996).

Similar species: Greater soapfish (Rypticus saponaceus) has grey to dark body color, lacks dark body spots. Spotted soapfish (R. subifrenatus) has tan to brown body color and pale borders around dark spots.

Size: 70 cm TL

Native Range: From the Red Sea to South Africa and east to French Polynesia and the Pitcairn Islands group, including northern Australia, Lord Howe Island and southern Japan. Throughout the Indo-Pacific except the Persian Gulf and Gulf of Oman. Early reports (from Valenciennes in 1828 and Quoy & Gammard in 1824) listed the species from Hawai’i; however, these reports are considered erroneous. Reports from western Indian Ocean (Heemstra and Randall 1984, 1986) are unsubstantiated, except one from Kenya (Smith 1954) which seems valid (Heemstra and Randall 1993). From Randall and Heemstra (1991), Heemstra and Randall (1993), Carpenter and Niem (1999), Randall (1983 and 2005) and Mundy (2005).

Nonindigenous Occurrences: In Florida, the species has been collected/observed in Tampa Bay (in 1984 [Courtenay 1995]), off Boca Raton (pre-1995 [Courtenay 1995]), in the Indian River Lagoon, near Cocoa (in 2003), off Pompano Beach (in 2005 and 2006 [REEF 2008]) and off West Palm Beach (in 2007 and 2011). A very large specimen (68 cm TL, approximately 15 lbs) was captured off Key Largo in December, 2012.

Scattered records from Hawaii are probably based on released aquarium fishes and the species was considered extirpated as of 2005 (Randall and Heemstra 1991; Mundy 2005).

Ecology: In its native range, this grouper occurs on coral reefs over a depth range of 1 to 40 m, typically less than 10 m. It is a protogynous hermaphrodite—individuals all begin as females then transition to males through time. In the wild, females mature at about 1.5 years and can start changing to males as early as 3 years.  By age 9, most fish are males.  Research from Australia indicates that panther grouper can live to at least 19 years in the wild. The species is an important food-fish throughout the Indo-West Pacific region; however, due to its carnivorous nature, it has been blamed for numerous cases of Ciguatera poisoning in both the native and introduced ranges. About 80% of the diet is fishes, while the remainder is mostly crustaceans (Heemstra and Randall 1993; Randall et al. 1996; Allen et al. 2003; Randall 1983, 1987, 2005; Williams et al. 2009).

Means of Introduction: Probably aquarium releases.

Status: Reported in Florida. Extirpated in Hawaii.

Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.

Remarks: The species is under heavy pressure from the aquarium industry (especially juveniles) and the commercial fishing industry. Additionally, large regions of its native habitat have suffered severe reef degradation. It is one of only two groupers assessed by the IUCN as "Endangered" (Morris et al. 2000).
