Genetics and Reproduction

Spawning grounds in the Sea of Swords, on the south shores of Koga Province in Tahoma

Growth Rate & Stages

Ikuchi give birth to live young which are between 6 and 10ft in length. These young will reach adulthood and usually a size of 50ft in a year. After this initial phase growth slows down exponentially to a few feet a year. The largest known Ikuchi was 450ft long

Ecology and Habitats

This species of sea serpent lives most of its life on the bottom of the Sea of Swords in coldest, deepest depths. Ikuchi is a stealth hunter, rising from its depths to prey on large sea creatures such a whales, dolphins, sharks and sometimes boats.

Dietary Needs and Habits

Ikuchi secrets an adhesive oil from a gland in its mouth which it uses to snare and retrieve its prey, dragging it down to the ocean floor where it coils its body around it, squeezing it until it breaks

Biological Cycle

Ikuchi Hibernates in a burrow beneath the seabed during the winter before resurfacing and shedding its old scales
