Many members of the scorpaenid subfamily: Sebastinae (rockfishes and their relatives) exhibit slow growth and extreme longevity (> 100 y), thus are estimated to be vulnerable to overfishing. Blackbelly rosefish (Helicolenus dactylopterus) is a deepwater sebastine whose longevity estimates range widely, possibly owing to different regional levels of fisheries exploitation across its Atlantic Ocean range. However, age estimation has not been validated for this species and ageing for sebastines in general is uncertain.

- Warsaw grouper (Hyporthodus nigritus) is a deep-sea fish found in the western Atlantic, currently listed as a species of concern and near threatened due to limited knowledge on its life history, particularly in the northern Gulf of Mexico (nGOM).
- Research established that nGOM Warsaw groupers can live up to 61 years, with age validation conducted using bomb 14C chronometry, confirming the accuracy of otolith aging methods.
- The findings suggest that juvenile Warsaw groupers inhabit shallower waters, and the study indicates significant overfishing of the species in the nGOM, as most caught fish are under 10 years old compared to their longevity.
