1. Research on rare and threatened species is often limited by access to sufficient individuals to acquire information needed to design appropriate conservation measures. %26lt;br%26gt;2. Using a combination of data from pop-up archival transmitting (PAT) tags across multiple institutional programmes, movements and habitat use of endangered smalltooth sawfish, Pristis pectinata were determined for animals from southern Florida and the Bahamas. %26lt;br%26gt;3. All P. pectinata (n=12) generally remained in coastal waters within the region where they were initially tagged, travelling an average of 80.2 km from deployment to pop-up location. The shortest distance moved was 4.6 km and the greatest 279.1 km, averaging 1.4 km day(-1). Seasonal movement rates for females were significantly different with the greatest movements in autumn and winter. %26lt;br%26gt;4. Pristis pectinata spent the majority of their time at shallow depths (96% of their time at depths %26lt;10 m) and warm water temperatures (22-28 degrees C). %26lt;br%26gt;5. Given sawfish show a degree of site fidelity punctuated by limited migratory movements emphasizes the need for conservation and management of existing coastal habitats throughout the species%26apos; range.Published 2013.
