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.

Zebrasoma flavescens (Bennett, 1828)

Common name: yellow tang

Synonyms and Other Names: lemon sailfish, somber surgeonfish, yellow sailfin tang

Taxonomy: available through www.itis.govITIS logo

Identification: Deep body with a slightly protruding snout and large dorsal and anal fins toward the posterior.   Bright yellow in color with white caudal spine (scalpel) (Allen et al. 2003).  White stripe along the lateral line in some specimens.  Dorsal fin V (23-26), anal fin III (19-22).  From Lieske and Myers (1994).

Similar species:  Juvenile blue tang (Acanthurus coeruleus) has a yellow scalpel and less-protruding mouth.

Native Range: The yellow tang is found in the Northwest and Central Pacific ocean from southwest Japan to Marianna Islands, Marshall Islands, Marcus Island, Wake Island and Hawai’i. From Allen et al. (2003).

Nonindigenous Occurrences: The species was observed eight times off Boca Raton between 2001 and 2005.  Seven of these sightings were of single fish, and one sighting was of two fish.  It has also been seen off Pompano Beach (2 fish in 2004, one individual in 2011), Delray Beach (3 fish in 2005), and Marathon (2011).The species has also been introduced to the Mediterranean Sea, likely from aquarium releases (Weitzmann et al. 2015).

Ecology:  The yellow tang is found in lagoonal and seaward reefs (Lieske and Myers 1994).  It is diurnally active, exhibiting a wide variety of social organization.  The species can be found in social groups ranging from solitary to hundreds of individuals while feeding during the day, but can also be found solitary in shelter sites during the night (Atkins 1981).  The yellow tang is the most frequently-collected aquarium fish in Hawai‘i (Tissot et al. 2004).  It has been observed to spawn seasonally, timing its reproduction to periods when the oceanographic currents are favorable for local recruitment to island populations (Lobel 1989).  The caudal spine is erectable as a defense mechanism (Winterbottom 1971).

Means of Introduction: Aquarium release.

Status: Reported in Florida.

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.
