Biography:

Jack Morris joined the Center for Shark Research in April of 2001 as a staff biologist and field support for a variety of shark migration projects. In 2005 he was promoted to senior biologist and manager of the Marine Experimental Research Facility. Since 2001, Jack has been involved with a diverse range of research projects that include field studies of shark nursery habitats, shark movements and migration patterns, habitat utilization, relative abundance of large coastal sharks and currently recreational and commercial post release mortality of sharks and shark physiology. In Addition, Jack designed and constructed the Marine Experimental Research Facility that has provided research tanks for a variety studies including; sensory capabilities, feeding morphology and kinematics, isotopic uptake and tag retention of sharks and rays.
