The Quillfish has an extremely elongate, slender body with lon-based tall dorsal and anal fins which make the fish similar in shape to the primary feather of a bird or a quill pen. The small head is only between 4 and 7% of the length of the body and there is a wide fleshy appendage at the front of the lower jaw.
The 100 species with longest life-spans recorded and verified [1] This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include:

All together, there are 1,270 species of killifish, the biggest family being Rivulidae, ... (56%) and maximum life span (59%) of Nothobranchius furzeri, ...
By another definition, however, maximum life span corresponds to the age at which the oldest known member of a species or experimental group has died. Calculation of the maximum life span in the latter sense depends upon the initial sample size. [1] Maximum life span contrasts with mean life span (average life span, life expectancy), and longevity.
The quillback rockfish (Sebastes maliger), also known as the quillback seaperch, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, the rockfishes, part of the family Scorpaenidae. This species primarily dwells in salt water reefs. The average adult weighs 2–7 pounds (0.9 – 3 kg) and may reach 1 m (3 feet) in length.
A bigmouth buffalo (top) compared to a quillback (bottom). Both of these species are long-lived catostomids [3] [5] The quillback is a slow-paced and long-lived freshwater fish species that belongs to a subfamily (Ictiobinae) for which extremely long-lived fishes are becoming known.
