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.

Chiloscyllium punctatum Müller and Henle, 1838

Common name: brownbanded bambooshark

Taxonomy: available through www.itis.govITIS logo

Identification: Juveniles exhibit alternating brown/white or black/white banding.  White bands become brown with maturity.  Body shape is long and slender.  Adults are light brown to greyish brown with no prominent color patterns.  Dorsal fins larger than pelvic fins.   Pectoral and pelvic fins forward of dorsal fin.  From Compagno and Niem (1998) and Allen et al. (2003).

Similar species: Nurse shark (Ginglymostoma cirratum) has a wider head, heavier body, and uniform grey to brown coloration.  Juvenile nurse sharks do not have color banding on the body.

Native Range: Brownbanded bamboosharks are distributed in the Indo-Asian Pacific from Madagascar and India to Indonesia and Philippines, north to southern Japan.  From Allen et al. (2003).

Nonindigenous Occurrences: In Florida, one individual was observed and photographed near Riviera Beach in 2007 (REEF 2008).

Ecology: The brownbanded bambooshark inhabits near-shore corals reefs and tide pools.  In Australia, the species prefers seagrass habitat, which could be a function of habitat partitioning with other near-shore sharks (White and Potter 2004).  The diet likely consists of invertebrates and small fish (Last and Stevens 1994).  The species is small and adapts well to captivity.  It can also withstand a wide range of environmental conditions, and breeding programs in Australia and Germany have been successful (Harahush et al. 2007).  Bamboosharks are on the IUCN Red List of Threatened Species and are classified as ‘Near Threatened’ globally.  In Australia, the bambooshark is classified as ‘Least Concern’ (Cavanagh et al. 2003).  The bambooshark is an oviparous species that lays brown rectangular egg cases attached to coral and rocky substrates by small and delicate tendrils (Harahush et al. 2007).

Means of Introduction: Probable aquarium release.

Status: Reported from 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.
