Yes, sea snakes are very poisonous and can live in saltwater. The most poisonous water snake is the Beaded Sea Snake. Just 3 drops of venom can kill about 8 people! AnswerParty!
Venom is the general term referring to any variety of toxins used by certain types of animals that inject it into their victims by the means of a bite, sting or other sharp body feature.
The potency of different venoms varies; lethal venoms are often characterised by the median lethal dose (LD50, LD50, or LD-50), expressed in terms of mass fraction (e.g., milligrams of toxin per kilogram of body mass), that will kill 50% of victims of a specified type (e.g., laboratory mice).
Wilderness medical emergencies
Venomous snakes are species of the suborder Serpentes that produce venom. Members of the families Elapidae, Viperidae, Atractaspididae and Colubridae are major venomous snakes.
Wilderness medicine is defined as a medical emergency which takes place in a wilderness or remote setting which is at least 60 minutes away from definitive care (hospital, clinic, etc.) and present unique challenges that may require specialized skills, treatment techniques, and knowledge in order to manage the patient for an extended period of time before being evacuated.
Poisonous amphibians are amphibians that produce toxins to defend themselves from predators.
Except certain salamandrid salamanders that can extrude sharp venom-tipped ribs, amphibians are not known to actively inject venom, most toxic amphibians are instead known to be poisonous to touch or eat. Amphibians usually sequester toxins from animals and plants that they feed on, commonly from poisonous insects or poisonous plants. One example of this is the well known poison dart frog. They get a deadly chemical called lipophilic alkaloid from consuming a poisonous plant in the rainforest. And they are immune to the poison so they secrete it through their skin as a defense mechanism against predators, just as other amphibians do. This poison is so efficient that the native people of the south American amazons use the frogs toxins on their weapons to kill their prey, giving the frogs their nickname the "poison arrow dart frog". However other people use the Bufotoxins of some species of toxic toads as a drug to get high, but this can become very dangerous. Usually due to the toads' size and toxicity the poisons would not be deadly to a fully grown, healthy adult. But if too much of the toxins are absorbed, or if the person is young or ill then the poisons can become a serious threat. It also depends on the species, because some types of amphibians do have toxins strong enough to kill even a healthy and fully matured person within just a few minutes, while other species may not have toxins potent enough to have any effect on you at all. In addition licking toads is not biologically practical. In order for these tryptamines to be orally activated, the human monoamine oxidase (MAO) system needs to be inhibited. Therefore licking a poisonous amphibian won't guarantee receiving a high sensation.
Wild Recon (Tuesdays at 9:00 pm Eastern/8:00 pm Central) is hosted by animal expert Donald Schultz. The show hosts many deadly animals such as: death adder, saltwater crocodile, lion and many other countless species that can take lives in an instance. Near the beginning of the show Donald states where he is, the main animals he's looking for, and then says "This is not a stunt; this is my job" and jumps out of the helicopter. Schultz's mission is to extract venom and other rare attributes of some of the world's deadliest, most intriguing animals. These samples are used to catalog information of lesser known species as well as research possible antidotes and medicinal uses. The first episode aired on Tuesday, January 5, 2010 at 9 pm Eastern time on Animal Planet.
