The spiny murex is a species of sea snail, native to the seas around New Zealand and Tasmania. The shell grows to roughly 3.5 – 6.5cm long, so it’s a tiny critter floating in a big ocean. Spines are distributed around the shell and act as a defence against predators. They tend to be shorter for murex living in shallower waters and longer in the deep.
The link below has some rather lush description of their eating habits…
