The most durable heat-resistant pigments are the carotin-based reds, and they are last to break down during boiling.

The same process occurs for most other hard-shelled crustaceans like shrimp, crab, and crawfish.

A common myth is that a lobster screams when boiled when it is actually the whistling sound from steam escaping the shell.

Many animal rights groups and advocates have long argued that lobsters feel pain and suffer when cooked, and this has led to many alternatives such as the Crustastun, which electrocutes lobsters with a 110 V electric shock, killing them in five seconds.

The practice of boiling lobsters is illegal in some countries, such as in Reggio Emilia, Italy, where the fine can be €495 for each offense.
