Description
editRhytididae are carnivorous.[1] They grow up to 33m in length and 19mm in height.[3][4] Their eggs are larger than other Rhytididae species.[4]
Ecology
editHabitat
editThe preferred habitat for Rhytididae in forests is under fern or leaf litter or in damp places under rocks.[4] They also live in sub-alpine zones in tussock or scrub.[4]
Distribution
editRhytida oconnori is found only at the top of the South Island in the Abel Tasman National Park south east of Tākaka, and at the Punipaua Creek near the Paturau River west of Collingwood in Golden Bay.[3][5][6]
Predators
editThe song thrush (Turdus philomelos), an introduced species to New Zealand, is a predator of Rhytididae.[1]
