A small fish that has discarded fins in favor of a living magnetohydrodynamic thruster.   ### 1. Monopter Fish are a common body plan across alien worlds, but they usually evolve fins or wings for propulsion. The hover thorn has just a single fin — a tail rudder at the base of the spinal braid. Spiracles behind the double eyes draw water for an internal gill.   ### 2. Doubled eye The hoverthorn's large primary eye is duplicated by a small secondary eye which contains columns of electro-active jelly. The hoverthorn can effectively see electromagnetic fields. The second eye was created by a duplication in the hoverthorn's HOLOX genes, which organize the thorn's body plan. A viral gene sequence copying itself throughout the hoverthorn's genome apparently copy-pasted the eye 'blueprint' several million years ago.   ### 3. Hoverthorn The hoverthorn's most incredible trait is its charge crystal, a mineralized swim bladder which fills the lower body cavity and protrudes from what was once a thruster orifice. A mineral Campbell matrix in the crystal organizes electric charge. When a portion of the crystal is charged, it polarizes and attracts surrounding seawater. Moving the charge along the crystal creates currents in the seawater — allowing the hoverthorn to generate and ride its own water currents.   ### 4. Mating behavior Hoverthorns joust with their charge crystals, approaching each other tail-first. As the crystals approach, their fields interact, and the weaker or less skilled hoverthorn will lose control. Both male and female hoverfish use this to either drive away or select fit mates.  -Assessment: fascinating.+**Assessment:** fascinating.  -*Source: Scan a Hoverthorn or Black Hoverthorn*+*Source: [Scan](Scan) a [Hoverthorn](Hoverthorn) or [Black Hoverthorn](Black_Hoverthorn)*   ## Gallery  -![The tail thorn appears to not move, relying on action from electrical activity for primary propulsion](Hoverthorn side.png)-![Eyes facing to the side](Hoverthorn front.png)-![No horizontal navigational fins evident](Hoverthorn top.png)-![The lighted tail is how this fish can often be spotted](Hoverthorn back.png)-![At night, these fish are quite visible from their luminescent tail thorn](Hoverthorn dark.png)+![The tail thorn appears to not move, relying on action from electrical activity for primary propulsion](Hoverthorn_side.png)+The tail thorn appears to not move, relying on action from electrical activity for primary propulsion+ +![Eyes facing to the side](Hoverthorn_front.png)+Eyes facing to the side+ +![No horizontal navigational fins evident](Hoverthorn_top.png)+No horizontal navigational fins evident+ +![The lighted tail is how this fish can often be spotted](Hoverthorn_back.png)+The lighted tail is how this fish can often be spotted+ +![At night, these fish are quite visible from their luminescent tail thorn](Hoverthorn_dark.png)+At night, these fish are quite visible from their luminescent tail thorn
