Coregonus fontanae is highly dwarfed, and is believed to be the world's smallest type of cisco [REF].
The Stechlin cisco is taxonomically distinguished from the vendace and the other dwarfed cisco species by its low number of lateral line scales (69-77), by some bodily proportions, by the length of its gill rakers, by its slow growth, by its glassy fins, and by its spring spawning season [REF].
