Next we observe the first species to exist as wards of the DOS, the Primary Belth (PB). A very docile species in daily activities, fighting, and when they are pushed to it, hunting. Mainly warded by the younger DOS when their progenitor dies before their ordained battle, these fish show little to no ability to defend themselves, with only grinding plates for processing their food and a diminutive stature of less than a meter, as well as their attitude, they simply do not have the wherewithal to defend themselves, and so the symbiotic relationship between them and the DOS was formed, less by force than by necessity. Of this relationship there are a few oddities not exhibited by other wards, particularly the total dependency on a DOS to guide them and the ability of the DOS to carry the eggs of more sickly PBs; further, they have an incredible relationship with young PBs, often having 100s of the creatures clinging to their body or otherwise swimming very close, although they do still retain a close relationship with their progenitors, the DOS becomes a secondary parental figure. Sometimes, however, a DOS is not present or available for an extended period of time to take on these duties. During these times, initially there is a great amount of confusion, and quite a number of the school is picked off by other fish and the occasional mammal, but eventually they find the closest natural structure and burrow as deep as they can go, and hibernate. Often this saves the school from being totally wiped out, although the number of them that are left alive is usually between 20 and 50; at the point where they come out of hibernation (note that hibernation cessation may be triggered biochemically by the DOS) they are again with a ward that protects them quite vigorously until their numbers are replenished.
