The hammerhead shocker split from its ancestor the marine shocker. It left the sea and now inhabit Yokto waterways. There it found the juvenile forms of many species in which it could prey upon. Its mouth has become a long trunk it which it can quickly grab food with. Like its ancestor its bite produces a strong electrical pulse that stuns its prey so it can eat it without it putting up a fight.
Its coloring is mostly brown to blend in with the brown mud of the Yokto waterways. However it has regained some of its distant ancestor's photosynthetic capabilities which make its fins green. Its side eyes have wide eye stalks that help it sense the faint electrical currents that all species give off. This can help detect prey even in muddy or murky water.
The mating season usually follows the spawning of the migrating glowsnapper. This ensure that their offspring will have plenty of prey species to feed on when they are born. When two adults of opposite sexes meet, they will enter a mating ritual in which they bite and electrify each other. The electricity stimulates them and thus prepares them for the actual mating. A few months after the female is fertilized, she will give live birth to young out of her "mouth womb". The young will stay with their mother until they are mature. Because the young are usually are not strong enough to kill their own prey, the father will instead bring dead prey to the family to eat together. When the young do reach maturity, they will leave their parents and proceed to live a life of their own. The mother and father will stay together for life.
