Stingray – Northern Arch
Northern Arch is a 40-metre-deep cut in a sheer rock wall at the northern end of the Poor Knights. Like a busy city alley it attracts hoards of life—thousands of fish.
For a month or two every five to ten years, massive aggregations of short-tailed rays.
The largest stingrays are the size of dining tables, but they are as docile as they are large, content to slide over a diver or come within arms-length of a snorkeler.
