Female California spiny lobsters reach sexual maturity at a length of 65–69 millimeters (2.6–2.7 in), which is typically at an age of 5–9 years; males are sexually mature after 3–6 years. [5] Because all the hard parts are lost at each molt, the life span of mature spiny lobsters is uncertain; [ 5 ] they are thought to live for 50 years ...
