Deep-Dwelling Fish Hadal snail fish, found off the coast of Japan at depth of 7700 m Deepest-dwelling fish found at 8372 m, did not survive trip to ocean surface Estimate pressure: p gage = ρ gh = 1000 kg/m 3 x 10 m/s 2 x 8000 m = 8x10 7 N/m 2 Assume an elephant weighs 6000 kg x 10 m/s 2 = 6x10 4 N Let’s say the roof of a compact car has an area of about 1.5 m x 1.5 m = 2.25 m
