The tiger rockfish has a long lifespan, reaching up to 116 years old. The tiger rockfish’s orangish-pink body has five, dark red stripes. They may be mistaken for the similarly colored redbanded rockfish, although the number of stripes differs between the two species. The dorsal and anal fins of the tiger rockfish contain spines that secrete painful venom, although it is non-lethal to those who are not allergic.
These rockfish favor complex habitats with many cracks and crevices in which they can hide. Areas with a rocky reef or high number of boulders are likely homes for the tiger rockfish.
