Portuguese man o' war
The Atlantic Portuguese man o' war lives at the surface of the ocean. The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged. As the Portuguese man o' war has no means of propulsion, they move according to the winds, currents, and tides. Although they are most commonly found in the open ocean in tropical and subtropical regions, they have been found as far north as the Bay of Fundy, Cape Breton and the Hebrides.
Fighting machine (The War of the Worlds)
In Pendragon Pictures' low-budget, direct-to-DVD "H.G. Wells' The War of the Worlds" (aka "Invasion" internationally or "War of the Worlds"), the only Victorian-set adaptation of Wells' novel, the tripod fighting machine design is loosely based on the look of a praying mantis, which, according to director Timothy Hines, was a favorite insect of H. G. Wells.
