This species has the smallest weight-for-weight brain size of any shark, reflecting its relatively passive lifestyle.

[7] They may be found in either small shoals or alone.
The bigeye thresher, A. superciliosus, is next in size, reaching a length of 4.9 m (16 ft); at just 3 m (10 ft), the pelagic thresher, A. pelagicus, is the smallest.
