The Selachians were distinguished by the Selachian battlesuits. These battlesuits were large, bulky things that gave the Selachians the appearance of humanoids. Selachians had to have studs implanted into their nervous system and have their tails removed in order for them to use the battlesuits. They had plasma weapons attached to their arms, which were built for fear rather than power (though it was still a dangerous weapon). Their helmets were shaped and painted to look like sharks in order to intimidate their enemies. Later battlesuits were equipped with nanites to repair damage and to counteract the nanites of the Terran Security Forces. (PROSE: The Final Sanction)
