Survival and growth of cultured juvenile sea cucumbers, Holothuria scabra
TLDR
It is concluded that it is possible to rear newly-settled H. scabra in land-based tanks using simple technology and little or no added feeds and there should be no major impediment to the large-scale production of juveniles for stock enhancement programs provided they can be released successfully at a size of 60 mm and 20 g.
Residency and Spatial Use by Reef Sharks of an Isolated Seamount and Its Implications for Conservation
TLDR
The high residency and limited spatial use of Osprey Reef suggests that reef sharks would be highly vulnerable to targeted fishing pressure and that MPAs incorporating no-take of shark would be effective in protecting reef shark populations at Ospreys and Shark Reef.
Nematocyst ratio and prey in two Australian cubomedusans, Chironex fleckeri and Chiropsalmus sp.
TLDR
An increase in the proportion of mastigophores (and presumably the lethal venom component) in the cnidome of C. fleckeri may also be responsible for why this species has caused numerous human fatalities, while the Australian Chiropsalmus sp.
Do elasmobranch reactions to magnetic fields in water show promise for bycatch mitigation
TLDR
The application of magnets worldwide to mitigate the bycatch of elasmobranchs appears promising based on these results, and a higher reliance on the electroreceptive sense to locate prey reacted to the magnets at the greatest distance, except G. glyphis.
Tide-related periodicity of manta rays and sharks to cleaning stations on a coral reef
TLDR
It is argued that observations of large elasmobranchs at cleaning stations are critical in elucidating previously unknown behaviours in elasmsobranch ecology and that hypotheses for tidal behaviour are discussed.
Chironex fleckeri (Box Jellyfish) Venom Proteins
TLDR
Characterization of two C. fleckeri venom proteins suggests that the toxins have a similar pore-forming mechanism of action involving α-helices of the N-terminal domain, whereas structural diversification among toxin members may modulate target specificity.
A rapid and repeatable method for venom extraction from cubozoan nematocysts.
TLDR
A new standardised technique for the recovery of venom from nematocysts of cubozoans is investigated to decrease the variation displayed between authors due to differing extraction techniques.
Costs of venom production in the common death adder (Acanthophis antarcticus).
TLDR
Examination of changes in metabolic rate in the Australian elapid Acanthophis antarcticus after venom expenditure and feeding as well as during preparation for shedding suggests that total costs of venom replenishment are relatively small when compared to costs of digestion and shedding.
Bites by spiders of the family Theraphosidae in humans and canines.
TLDR
Bites by Australian theraphosid spiders are unlikely to cause major problems in humans, but the study demonstrates that the venom is far more toxic to canines.
Spawning induction of three tropical sea cucumbers, Holothuria scabra, H. fuscogilva and Actinopyga mauritiana
TLDR
Collection, transport and thermal stress was an effective spawning induction method for H. fuscogilva and A. mauritiana and further research should target improved spawning induction through the conditioning and holding of captive broodstock.
