The South Polar Shardgill split from its ancestor. It derives its name from how its thin shiny body resembles a shard of glass. It thrives in colder waters, forming massive schools which roam the southern oceans. It is a more agile swimmer than its ancestor. While it is a generalist like its ancestor, it prefers to chase down small fauna than picking up free-floating organisms. Other than these changes, it is the same as its ancestor.
