Magneta

Magneta is a domain in Tetrian biosemantics consisting of just four species: the Iola Beetle, Court Spider, Peltrian, and Silodrid. Modern Magnetates evolved from a single species of Protomagnetate that lived on Zorvalgia 550 million Earth-years ago.

Defining Characteristics
The bodies of Magnetates are filled with immense quantities of coiled conductive material in which electrical current is induced when the organism is in close proximity to the magnetic field of a planet or star that is moving relative to it. Water ingested or absorbed by the organism and stored in the body is electrolyzed and combusted by the electricity, in the same way as in Photonates.
