A pregnant sand tiger shark is quickly tagged and measured. The team places a pipe in her mouth with running water so she can still breathe through her gills.

A scalloped hammerhead shark is secured to the boat while it is measured and tagged. An 'aerator' placed in its mouth allows water to be pumped over its gills. (Image is from video taken by Tanya Griffin Houppermans)
