Clinton, the mechanics aren't wet vs dry, but engorged with fluid so hooks interlock with intestinal walls/wound tissue, vs not engorged so they disconnect from same. You're right, in this environment everything is wet, so getting something dry is not possible, hence, this clever design.
Wow. They have to look pretty hard for examples in nature to find this parasite's ability to hook onto fish intestines. Fascinating story, Ann. By the way, I recently found out that a hearty 60 percent of species on earth are parasitic, while only 40 percent are non-parasitic.
Nice article Ann. Yet another product approach inspired by nature's handiwork.
