Chalder

The Chalder, or Chaldor, were a sentient species from the planet Chalderescol II. Their physiological classification was AUGL.

Physiology
They were armored, fish-like water-breathers who could not live in any other medium for more than a few seconds. They slightly resembled forty-foot long armour-plated Earth crocodiles, except that instead of legs they had stubby fins and a heavy knife-edged tail. A fringe of ribbon-like tentacles encircled the body's middle, projecting through some of the only openings visible in the organic armor.

Chalders had six rows of teeth in their over-large mouths. ("Sector General")

Culture
Chalders were one of the few species who used personal names only between mates, members of the immediate family, or very special friends.
