Carcharhinidae 1359
Carcharhinus sp.
En - False smalltail shark.
Maximum total length at least 43 cm, probably attains a maximum length of about 1 m as a term
fetus is 34 cm total length and a freeliving individual with an umbilical scar is 37 cm total length. A
rare, little-known inshore tropical shark endemic to the area, previously confused with the American
smalltail shark, Carcharhinus porosus (Ranzani, 1839) but closer to (but distinct from) C. borneensis.
Presumably viviparous. Probably occurs in local fisheries, but of minor interest. Known only from 3
specimens from Viet Nam (Ho Chi Minh City), Borneo (Baram, Sarawak), and Thailand (Bangkok).
Conservation status needs investigation.

Glyphis sp. A [Last and Stevens, 1994]
En - Queensland river shark.
Maximum total length at least 75 cm (newborn specimen with umbilical scar), probably attains a
much larger size. A rare, little-known tropical riverine shark. Probably occurs in local fisheries, but
of minor interest. Known from 2 specimens from the lower reaches of the Bizant River in Queensland,
Australia, probably in brackish rather than fresh water. Possibly identical with the speartooth shark,
Glyphis glyphis (Müller and Henle, 1839) which was described from a single stuffed specimen
without locality. Conservation status needs investigation.
