Original Description

The arrowhead has grown ten times the size of its ancestor, the needlehead, thus it has become macroscopic. It has spread along the coasts of Barlowe and Dixon, and live in temperate to tropical waters. They no longer asexually bud but now produce spores within their bodies which then exit via the spaces in the body segment directly before the tail. The spores rapidly develop and the young will rapidly reach adult size and will be able to reproduce themselves within 3 weeks. They can live to be 2 years old before succumbing to old age.

The head region has developed a primitive "jaw" that formed from the segment that once existed their beforehand. They filter-feed via this, and inside of it is innumerable microscopic tentacles that contain specialized stinging cells to immobilize and ensnare the food it eats. A series of holes along the upper portion of its head take in water like a gill, pass it through the body where the oxygen and salt is removed, and then release it via the spaces within the segments just before the tail. It has evolved a duel brain cell cluster system, with the upper brain cell cluster controlling movement and its active actions such as feeding while its lower brain performs passive actions such as breathing and bodily functions.

Just behind the head is a specialized organ that allows it to "see" via detecting the electric byproducts produced via living organisms, allowing it to find its predators, be they either camouflaged, hidden under sand, or coming from behind. The organ is soft and porous, like a sponge, and is directly connected to the lower brain cell cluster.

The circulatory system consists of a three primitive two-chamber hearts attached to one another, and they pump the coboglobin-rich blood throughout the fauna's body. The coboglobins tint the arteries pink and the veins a yellowish amber-like hue.

Its body has developed a thicker segmented armor to protect it from potential predators, save for the segment just before the tail. This segment is heavily sub-segmented to allow greater flexibility, and each sub-segment has spaces between them that allows water to exit it as well as its young and waste. It has further developed its paddle-like tail into larger, stronger swimming utensil in order to allow it to better escape its predators.

This species tends to live in small shoals, communicating with one another with controlled bio-electric pulses. They do not care for their young, and will remain in near the surface while their offspring inhabit the deeper waters to feed on the various salt moss species. They have adapted to feeding on species that are not filled with salt, and have now become less salt dependent.

Reproduction occurs at around 3 weeks of age, and will continue every 4 weeks following that, with each birth producing dozens of spores the size of a pinhead. Larger individuals will produce more young, and will also tend to have larger, healthier offspring. Their numbers have greatly grown because of this, and have become an important part of the food chain in the areas they live in.
