Deep living for centuries We tend to think of vertebrates as living about as long as we do, give or take 50 to 100 years. Marine species are likely to be very long-lived, but determining their age is particularly difficult. Nielsen et al. used the pulse of carbon-14 produced by nuclear tests in the 1950s—specifically, its incorporation into the eye during development—to determine the age of Greenland sharks. This species is large yet slow-growing. The oldest of the animals that they sampled had… 
Comment on the ecophysiology of the Greenland shark, Somniosus microcephalus
This application of the standard DEB model shows that it can be applied in situations where few data are available and how implied properties (gestation) can be used to constrain parameter values.
Teleost and elasmobranch eye lenses as a target for life-history stable isotope analyses
It is shown that fish eye lens protein is an attractive host for recovery of stable isotope life histories, particularly for juvenile life stages, and especially in elasmobranchs lacking otoliths, but interpretation of lens-based records is complicated by species-specific uncertainties associated with lens growth rates.
Age of black dogfish (Centroscyllium fabricii) estimated from fin spines growth bands and eye lens bomb radiocarbon dating
A discrepancy between age estimates obtained from fin spines and bomb radiocarbon dating is observed, indicating thatfin spines are unsuitable for ageing black dogfish, at least for the oldest individuals.
Assessing the reproductive biology of the Greenland shark (Somniosus microcephalus)
This study represents the first comprehensive work on Greenland shark reproductive biology based on data from 312 specimens collected over the past 60 years and provides guidelines quantifying reproductive parameters to assess specific maturation stages, as well as calculate body length-at-maturity (TL50).
A first look at the metabolic rate of Greenland sharks (Somniosus microcephalus) in the Canadian Arctic
It is shown that despite recording very low whole-animal resting metabolic rates for this species, estimates are within the confidence intervals predicted by derived interspecies allometric and temperature scaling relationships, suggesting this species may not be unique among sharks in this respect.
Estimating the Age of West Greenland Humpback Whales Through Aspartic Acid Racemization and Eye Lens Bomb Radiocarbon Methods
To maintain a sustainable harvest of marine mammals, knowledge on key life history parameters such as age is essential. In West Greenland, humpback whale numbers were low during the 1980s due to past
Life history, growth, and form
First estimates of Greenland shark (Somniosus microcephalus) local abundances in Arctic waters
The baited camera results illustrate the ubiquity of this elusive species and suggest that Nunavut’s Lancaster Sound eco-zone may be of particular importance for Greenland shark, a potentially vulnerable Arctic species.


Vertebral Bomb Radiocarbon Suggests Extreme Longevity in White Sharks
The results dramatically extend the maximum age and longevity of white sharks compared to earlier studies, hint at possible sexual dimorphism in growth rates, and raise concerns that white shark populations are considerably more sensitive to human-induced mortality than previously thought.
Bomb dating and age determination of large pelagic sharks
The results indicate that porbeagle vertebrae recorded and preserved a bomb radiocarbon pulse in growth bands formed during the 1960s, and confirm the validity of por beagle vertebral growth band counts as accurate annual age indicators to an age of at least 26 years.
Growth analysis and age validation of a deepwater Arctic fish, the Greenland halibut (Reinhardtius hippoglossoides)
The accuracy of age interpretations on a deep-sea, Arctic fish species, the Greenland halibut (Reinhardtius hippoglossoides) was tested using several age validation methods. Consistent annual growth
Age under-estimation in New Zealand porbeagle sharks (Lamna nasus): is there an upper limit to ages that can be determined from shark vertebrae?
The results suggest that older porbeagles were under-aged by as much as 50% from vertebral band counts, presumably because band width declined to a point where it became unresolvable, which has important implications for growth studies on other long-lived sharks.
Age and growth estimates of bowhead whales (Balaena mysticetus) via aspartic acid racemization
A total of 48 eye globes were collected and analyzed to estimate ages of bowhead whales using the aspartic acid racemization technique, and growth appears faster for females than males, and age at sexual maturity occurs at around 25 years of age.
Bomb dating and age validation using the spines of spiny dogfish (Squalus acanthias)
The results indicate that the dorsal spines of spiny dogfish, Squalus acanthias, recorded and preserved a bomb radiocarbon pulse in growth bands formed during the 1960s with a timing which was very similar to that of marine carbonates.
Distribution and feeding ecology of the Greenland shark (Somniosus microcephalus) in Greenland waters
The results of this work support the notion that the Greenland shark is an apex predator with the potential to influence trophic dynamics in the Arctic.
Use of radiocarbon from nuclear fallout as a dated marker in the otoliths of haddock Melanogrammus aeglefinus
The first preand post-bomb I4C chronology based only on young fish otoliths is reported, thus avoiding all assumptions concerning the age and dale of uptake into the otollth, and any requirement for reference coral chronologies.
