This year’s marine heat waves and spiking ocean temperatures foretell big changes in the future for some of the largest fish in the sea, such as sharks, tunas and swordfish.
Sawfish are mostly found in relatively shallow waters, typically at depths less than 10 m (33 ft), [2] and occasionally less than 1 m (3.3 ft). [61] Young prefer very shallow places and are often found in water only 25 cm (10 in) deep. [4] Sawfish can occur offshore, but are rare deeper than 100 m (330 ft). [2]
