Spiny murex

Peter “Chazz” Marriott, NIWA/ Oceans Survey 20/20 Chatham-Challenger expedition.
Formidable defences; you would find it hard too to eat this little spiny murex if you were a fish. This specimen is around 3 cm long and was collected from around 540 m on the Challenger Plateau north-west of New Zealand.
