The lurkfish grows 13 feet (4.0 m) long and lives in the Bengal Swamp. The lurkfish is descended from the electric catfish. When East Africa split from Continental Africa, it went further to the east, colliding with South Asia and creating a big swamp with brackish waters.
Lurkfish has evolved a sophisticated way of killing venomous swampuses: electricity. The lurkfish has a massive head, branch-like barbs, and an elongated body. All those can advance its surface area to store muscle blocks that produce electricity. To hunt, it creates a weak electric field and detects whatever movement goes through the field. Once its victim comes within range, it releases a thousand volts to stun its prey. Then the lurkfish can eat in leisure. This behavior is similar to many electric fish in murky, brackish water - such as the electric eel. It occupies a similar niche to crocodiles. If the lurkfish is stranded on shore it can easily slide back into the water. It can also breath through its skin. Male lurkfish defend territories along with the females that dwell in them. He will mate with the females and produce a large amount of offspring which can care for themselves.
