Lumicauda testucanus

From OurFoodChain

Ancestor is unknown 12 cm (head to tail) L. testucanus is a small aquatic organism with an exoskeleton. They swim through the water quite efficiently using their six sets of fins. A pair of long antennae are located on top of their head, allowing them to sense disturbances and movements in the water around them. The light at the end of their tail is the result of several chemicals, once a defense mechanism in an older member of their lineage, being mixed together. At night, these lights can be seen flashing in the shallow waters of Zone 29, and males use these lights to attract mates. Fertilization takes place externally, with females laying their eggs on C. viriclavus, and males fertilizing them. Clutches consist of 5 - 10 eggs. Three fourths will typically reach maturity, those not surviving becoming dislodged and being swept out of the channel. L. testucanus is a herbivore, and use their mouthparts to feed on the relatively soft body of C. viriclavus.
