Largetooth Sawfish (Pristis perotteti)
Species Description
Sawfish are generally a tropical marine and estuarine elasmobranch (shark and ray relative). All modern sawfish appear to be more shark-like than ray-like, with only the trunk and especially the head ventrally flattened. The presence of a rostrum having laterally protruding teeth separates sawfish from skates and rays. The rostrum has a saw-like appearance, hence the name “sawfish.” The largetooth sawfish and smalltooth sawfish are similar in appearance, but can usually be differentiated by the number of teeth on one side of the rostrum. Smalltooth sawfish (Pristis perotteti)can have between 14 and 21 rostral teeth on one edge of the saw, whereas largetooth sawfish (Pristis pectinata) usually has 23 to 34.
