Distribution
This species occurs in the northern parts of the South Island of New Zealand.[1] The only individuals have been found between 2,000 and 2,500 ft from the Oparara River near Karamea, to Gunner Downs south of the Heaphy River.[2][3]
Life cycle
The shape of the eggs of this species is oval. They are seldom constant in dimensions, varying from 9 × 8 mm to 9 × 8.5 mm.[4]
gollark: Password hashing algorithms generally let you pass the salt as a separate parameter.
gollark: Anyway, good password hashing algorithms are designed to be hard to parallelize, and to require large amounts of memory, so that they're hard to implement on FPGAs/ASICs/GPUs and run fastest on general-purpose CPU hardware (this is what your server has).
gollark: Basically!
gollark: Also a salt per password.
gollark: Basically, with passwords, you want a hashing algorithm which is somewhat slow so that it can't be bruteforced.
