This study provides comprehensive proteomic profiles from the venom producing posterior salivary glands of octopus (superorder Octopodiformes) species. A combined transcriptomic and proteomic approach was used to identify 1703 proteins from the posterior salivary gland of the southern blue-ringed octopus, Hapalochlaena maculosa and 1300 proteins from the posterior salivary gland of the southern sand octopus, Octopus kaurna. The two proteomes were broadly similar; clustering of proteins into orthogroups revealed 937 that were shared between species.

BMed, FACEM, Emergency Staff Specialist and Clinical Toxicology Fellow, Clinical Toxicology and Pharmacology, Calvary Mater Hospital, Newcastle, NSW.

Article Synopsis
  • Marine stings are typically minor and do not need medical treatment, but severe cases can result from box jellyfish, Irukandji syndrome, stingray trauma, or blue-ringed octopus bites.
  • The article focuses on how these marine injuries and envenomations present in Australia and their management, including urgent first aid measures.
  • Effective first aid for jellyfish stings involves removing tentacles, using vinegar for box jellyfish, and immersing in hot water for bluebottle stings, while severe cases may require basic life support and careful treatment of penetrating injuries to prevent complications.

Death in the octopus' garden: fatal blue-lined octopus envenomations of adult green sea turtles.

Mar Biol

December 2011

Independent Marine Biochemistry Research, Moreton Bay Research Station, P.O. Box 138, Dunwich, QLD 4183 Australia.

The blue-lined octopus contains the powerful neuromuscular blocker tetrodotoxin (TTX), which causes muscle weakness and respiratory failure. is regarded as one of the most venomous marine animals in the world, and multiple human fatalities have been attributed to the octopus. To date, there have been no recorded incidents of an envenomation of a wild animal.

In addition to blunt and sharp trauma, animal-related fatalities may result from envenomation, poisoning, anaphylaxis, asphyxiation, and sepsis. Although the majority of envenomation deaths are caused by hornets, bees, and wasps, the mechanism of death is most often anaphylaxis. Envenomation resulting from the injection of a poison or toxin into a victim occurs with snakes, spiders, and scorpions on land.

Encounters with venomous sea-life.

J Emerg Med

January 2011

Universidad de Monterrey, Monterrey, Nuevo León, México.

Background: Sea-life with envenomation capabilities are quite abundant and diverse worldwide, being predominantly found in tropical waters. Most envenomations occur not as an attack, but as a result of self defense when the animal perceives danger; and often when locals or tourists are engaged in recreational activities. Most of these cases have only minor injuries, and few are fatal.

Neurotropic effects of venoms and other factors that promote prey acquisition.

J Exp Zool A Ecol Genet Physiol

September 2007

Department of Anatomy and Cell Biology, College of Medicine, University of Florida, Gainesville, Florida, USA.

Mammals envenomed by either the Eastern diamondback rattlesnake (Crotalus adamanteus) or the cottonmouth (Agkistrodon piscivorus piscivorus) exhibit an immediate but transitory pupillar contraction, a parasympathomimetic effect mediated through the ciliary ganglion that can be prevented by a retrobulbar injection of anesthetic. The venom of the cottonmouth injected into the lymph spaces of the frog (Rana pipiens) produces an immediate and total collapse of the lung sacs. Applied locally to the surface, it produces a constriction that eventually collapses the entire sac.

Struan Sutherland--Doyen of envenomation in Australia.

Toxicon

December 2006

Australian Venom Research Unit, Department of Pharmacology, The University of Melbourne, Australia.

Struan Sutherland (1936-2002) was the doyen of medical research in the field of envenomation and the ultimate authority on the medical management of envenomated victims in Australia for almost 3 decades. In 1981 as Head of Immunology Research of Commonwealth Serum Laboratories (CSL), he produced an antivenom against the Sydney Funnel-web Spider (Atrax robustus)-an accomplishment that had defied numerous previous attempts. Struan also invented the pressure-immobilisation technique of first-aid for snake bite.

Marine antivenoms.

J Toxicol Clin Toxicol

There is an enormous diversity and complexity of venoms and poisons in marine animals. Fatalities have occurred from envenoming by sea snakes, jellyfish, venomous fish such as stonefish, cone snails, and blue-ringed octopus. Deaths have also followed ingestion of toxins in shellfish, puffer fish (Fugu), and ciguatoxin-containing fish.

Article Synopsis
  • - Tropical Australia is home to a vast array of venomous creatures, including the highly dangerous box jellyfish and various aggressive spiders, but notably lacks tiger snakes among its elapid snakes.
  • - The taipan snake has the most efficient biting mechanism and its venom causes serious health issues such as blood clotting problems, nerve damage, and muscle deterioration.
  • - Brown snakes now lead to the majority of snake bite fatalities in Australia due to their venom's effects on blood clotting and potential heart complications, alongside other dangerous animals like blue-ringed octopuses and stonefish.

Article Synopsis
  • The study examined the impact of venom from the blue-ringed octopus and tetrodotoxin (TTX) on anaesthetized rats and rabbits, focusing on how these toxins affect respiratory function and blood pressure.
  • The toxins led to paralysis of respiratory muscles, resulting in anoxia (lack of oxygen) and cyanosis (bluish skin), which could be addressed with positive, artificial respiration.
  • Additionally, the research tested various drugs like noradrenaline and phenylephrine to counteract severe drops in blood pressure caused by the toxins, which hindered normal nerve signaling.
