Nematodes leap from one soil particle to another using built up surface tension to catapult themselves.

"Surface tension gets put to use by a nematode, which leaps from one soil particle (through air) to another. It holds itself in a U-bent spring with a drop of water; failure of the droplet to stay together straightens it suddenly enough to catapult the nematode upward and laterally (Dusenbery 1996)." (Vogel 2003:449-450)

"The mechanism enabling entomopathogenic [insect parasitic] nematodes (Steinernema

spp.) to jump is described. Jumping performance is measured and the

contribution of jumping to host finding is estimated. We used the

entomopathogenic nematode Steinernema carpocapsae as a model

species for the genus. Nematodes jump using a two-step process of

forming and contracting a loop. During loop formation, the nematode

bends the anterior half of its body until the head region makes contact

with the side of the body. The two body regions are held fast by the

surface tension of the water film covering the nematode. When the loop

is contracted, the body becomes contorted so that the cuticle kinks.

This extreme bending generates and stores sufficient energy that when

the surface-tension force is broken the nematode is propelled through

the air. The nematode (0.558 mm in length) can jump a distance of 4.8 ±

0.8 mm (mean ± SEM) and a height of 3.9 ± 0.1 mm. The contribution of

jumping to host finding varies among species and is related to the

foraging strategy used by each species." (Campbell and Kaya 1999:1947)
