Lobsters have a total of 100,000 neurons. In the overall scheme of things, this isn’t many. It’s less than half those of an ant and a tenth of those of a cockroach.
By contrast, a rabbit has nearly 500 million neurons. (Humans, in case you are interested, have around 86 billion.)
So it seems inconsistent at the very least that it is illegal in New Zealand to cause a couple of minutes of bubbling suffering to an animal with almost no feeling, on the basis that they nevertheless do have a functioning nervous system. Yet it is fine to cause up to four days of suffering to an animal with a sophisticated nervous system.
This seems an appropriate place to drop in a link to DFW’s Consider the Lobster (pdf).
