Parthenogenesis in a whitetip reef shark Triaenodon obesus involves a reduction in ploidy
Journal of Fish Biology, 2014Genetic analysis of a female whitetip reef shark Triaenodon obesus and her stillborn pup, assumed to be of parthenogenetic origin, revealed that the pup was homozygous at all 24 nuclear‐encoded microsatellites assayed, consistent with the idea that diploidy in the pup had been restored via terminal fusion.

Serum T4 and serum T3 concentrations in immature captive whitetip reef sharks, Triaenodon obesus
Journal of Experimental Zoology, 1999Serum T(3) (3,5,3' triiodothyronine) and serum T(4) (thyroxine) concentrations were repetitively assayed by radioimmunoassay over a three-year period in two male and two female immature captive whitetip reef sharks, Triaenodon obesus. These sharks were maintained at the Waikiki Aquarium, Honolulu, Hawaii, in an open system holding pool receiving 568 ...

Mitochondrial DNA Part A, 2014
The complete mitochondrial genome of the whitetip reef shark Triaenodon obesus is determined in this study. It is 16,700 bp in length, with the typical gene composition, arrangement and transcriptional orientation in vertebrates. The overall base composition is 31.4% A, 25.8% C, 13.2% G and 29.7% T. Two start codons and two stop codons are found in the

Serum corticosterone concentrations in immature captive whitetip reef sharks, Triaenodon obesus
Journal of Experimental Zoology, 1993AbstractSerum concentrations of the steroid hormone corticosterone were monitored over a four‐year period in two male and two female immature captive whitetip reef sharks, Triaenodon obesus. Corticosterone concentrations in the serum ranged from 69–999 pg/ml (319.8 ± 31.9; n = 36) for males and 3–246 pg/ml (116.0 ± 15.1; n = 32) for females.

Animal Behaviour, 2004
We analysed video records of three mating events involving nine free-living whitetip reef sharks in Cocos Islands, Costa Rica to examine reproductive behaviour in this species. We describe several behaviours never before documented in this species, and four behaviours never before documented in any elasmobranch.

Triaenodon obesus (Rüppell) (Fig. 4A) A tissue sample was taken from a frozen specimen of Triaenodon obesus (SL-119) that had been collected earlier in 2018 from the Negombo fish market in Negombo in the Western Province. This specimen has now been deposited in the BRT Ichthyology Collection (BRT-I 0031).

ABSTRACTFour observations of what was probably a single vagrant adult female whitetip reef shark Triaenodon obesus were made at Raoul and Meyer Islands, Kermadec Islands, New Zealand, over a 12 month period in 2014/15. This is the most southerly occurrence of the whitetip reef shark and ambient winter temperatures were close to the assumed thermal ...
