    • ‘This particular horse mussel was collected from Evans Bay, Wellington, and is 30 cm long.’
    • ‘The horse mussel is mostly found outside the tidal zones but still can be found within them.’
    • ‘Once individuals reach 45-60 mm in length they become relatively immune to predation as only the very largest crabs and starfish can open horse mussels over 50 mm in length.’
