Abstract EN
A collection of nine shark specimens from six different species, obtained in 1993 from the Gulf of Thailand, was examined in this study.
The sharks were determined, morphometrically and meristically analyzed, photographically documented, and compared with relevant literature.
Additionally, further available material from the fish collections of the Zoological Museum Hamburg, the Senckenberg Naturmuseum Frankfurt, and the Muséum national d’Histoire naturelle, Paris, was examined by way of comparison.
Contrary to most references, prominent dorsal ridges were detected in several specimens of Chiloscyllium griseum.
Additionally, one of the specimens had a very unusual big ocellar blotch on the head which had not been reported for this genus before.
For Paragaleus randalli, it could be proven that the teeth morphologically deviate strongly from those shown in literature due to having much larger cusps.
Furthermore, the known distribution area of Paragaleus randalli could be extended considerably eastwards by about 2000 km.
For a seventh species, Paragaleus tengi, differences between the actual morphology of upper lateral teeth and those drawn in the original description were detected.
