Sawfish
The dwarf and largetooth sawfish are strictly warm-water species that generally live in waters that are and respectively. The green and smalltooth sawfish also occur in colder waters, in the latter down to , as illustrated by their (original) distributions that ranged further north and south of the strictly warm-water species. Sawfish are bottom-dwellers, but in captivity it has been noted that at least the largetooth and green sawfish readily take food from the water surface. Sawfish are mostly found in places with soft bottoms such as mud or sand, but may also occur over hard rocky bottoms or at coral reefs. They are often found in areas with seagrass or mangrove.
Sailfin roughshark
Since this species lives in the depths where deepwater fisheries operate, they can have a negative impact on the already uncommon species by being the bycatch of these offshore fisheries. Although their population is unknown, most of its population is in the deeper offshore waters and very few are in the inshore waters.
