Lead author Jeffrey Karp, a researcher at Brigham and Women's Hospital, has a habit of looking to the natural world for adhesive ideas, such as gravity - defying gecko feet or grasping
porcupine needles.
This may reveal retained food debris, lodged foreign objects (
needles, sticks, bones,
porcupine quills, others), tumors, ulcers, inflamed tissue, bleeding tissue, weeping sores and / or other non-healing wounds.
Here's some of the fish I've seen while snorkeling at Black Rock: Butterfly fish, parrot fish, damsel fish, surgeon fish, moorish idol, tang, wrasse, box fish, cardinal fish, perch, chub, trigger fish, the former Hawaii State Fish Humuhumunukunukuapuaa, goat fish, snapper,
porcupine fish, hawk fish, jacks, mackerel, cornet fish,
needle fish, turtles, crustaceans, and invertebrates.
