چکیده

Owing to poorly mineralising structures, ageing deep-water elasmobranchs requires unconventional techniques. The aim of the present study was develop an method for goblin shark Mitsukurina owstoni (Jordan, 1898) using Alcian blue staining vertebral column. One centrum from a male individual measuring 315.2-cm total length (TL) aged with minimum age 27 years. Using Bayesian von Bertalanffy growth model informed by back-calculated at age, literature search maximum TL, TL smallest free-swimming individuals and informative priors, we estimated males grow 374cm mature 16 years live up 60 Our results provide useful life history information, elucidating cryptic biology this shark.

Slingshot feeding of the goblin shark Mitsukurina owstoni (Pisces: Lamniformes: Mitsukurinidae)

The goblin sharks swung their lower jaw downward and backward to attain a huge gape and then rapidly protruded the jaws forward a considerable distance. The jaws were projected at a maximum velocity of 3.1 m/s to 8.6-9.4% of the total length of the sh...

Preliminary Investigations into the Age and Growth of the Shortfin Mako, Isurus Oxyrinchus, White Shark, Carcharodon Carcharias, and Thresher Shark, Alopias Vulpinus, in the Western North Atlantic Ocean

Preliminary analysis of the vertebrae of these three species indicate that the current processing method is adequate for counting bands. Sample collection is ongoing and it is likely that more will be obtained for the shortfin mako and thresher shark, though not for the white shark. Complete studies on the age of these species using the entire vertebral samples, tag/recapture data and length fr...

On the Compaction and Viscous Behavior of Deep-Water Reservoirs

There have been many studies on reservoir compaction where different mechanisms being suggested as the reasons behind the integrity of unconsolidated reservoirs during production. Theory of poroelasticity is often used to evaluate the likelihood of compaction under these circumstances, but it is often failed to explain the creep behavior of unconsolidated formations. In this study, attempts are...
