Venom optimization hypothesis, also known as venom metering, is a biological hypothesis which postulates that venomous animals have physiological control over their production and use of venoms. It explains the economic use of venom because venom is a metabolically expensive product, and that there is a biological mechanism for controlling ...
Venom metering is the ability of a snake to have neurological control over the amount of venom released into a target during a strike based on situational cues. This ability would prove useful as venom is a limited resource, larger animals are less susceptible to the effects of venom, and various situations require different levels of force.
Envenomation is the process by which venom is injected by the bite or sting of a venomous animal. [1]Many kinds of animals, including mammals (e.g., the northern short-tailed shrew, Blarina brevicauda), reptiles (e.g., the king cobra), [2] spiders (e.g., black widows), [3] insects (e.g., wasps), and fish (e.g., stone fish) employ venom for hunting and for self-defense.
“The cornerstone of therapy for snake bites is antivenom treatments, and it’s been around for about 120 years,” said Dr. Charles Gerardo, an emergency medicine specialist at Duke Health ...
• For dry bites: These types of bites are either by non-venomous snakes or by venomous snakes that did not inject any venom into the victim. They do not need antivenom, as there is no venom to ...
The pressure immobilisation technique is a first aid treatment used as a way to treat spider bite, snakebite, bee, wasp and ant stings in allergic individuals, blue ringed octopus stings, cone shell stings, etc. [1] [2] The object of pressure immobilisation is to contain venom within a bitten limb and prevent it from moving through the lymphatic system to the vital organs.
Antivenom, also known as antivenin, venom antiserum, and antivenom immunoglobulin, is a specific treatment for envenomation. It is composed of antibodies and used to treat certain venomous bites and stings. [1] Antivenoms are recommended only if there is significant toxicity or a high risk of toxicity. [1]
Little is known about the black-headed cat snake's venom toxicity on humans, but it is thought to be comparable to the severity of a copperhead. This rear fanged colubrid's bite rarely results in adverse effects due to its poor venom delivery system. Luckily their fangs' positioning doesn't result in any significant envenomation.
