The lightvesting filtersquid has replaced its ancestor in the equator zone of Sagan 4’s oceans while its ancestor still strives in the north and south. The main difference between the lightvesting filtersquid and its ancestor is its symbiotic adaptation. While the flashing filtersquid uses the flash cells in its massive back sack to scare predators the lightvesting filtersquid rarely uses this quality. Instead it has adapted to use the flash cells for photosynthesis. While the flash cells provide it with photosynthetic byproducts it gives them a safe environment and their basic needs like exposing them to light, providing them with CO2 and other nutrients they need.
The flash cells are now contained in four sacks above their jet mouths. The lightvesting filtersquid therefore often swims along the sea face with its cone heading up to gain more light. Unlike its ancestor the flashing filtersquid only leaves the sunlight zone into the depth of the twilight zone at night.
It has also evolved small fins in the end of its six limbs for better rapid movement. It has grown slightly in size due to its new always available energy source.
