They can move faster than snakes. When a venomous snake is trying to bite the mongoose, the mongoose is fast enough to avoid the bite many times. When the snake gets too tired, the mongoose eats the snake.\n\nContrary to popular belief, the mongoose is NOT immune to snake venom.

Scorpions are arachnids and so are related to spiders. Their venom acts in much the same way that spider venom does. It generally has neutroxic (attacks the nervous system), hemolytic (destroys red blood cells), coagulant (causes blood clots) and cardiotoxic (attacks the heart) properties.\n\nSnakes on the other hand do not have venom, they use poison to attack their victims. Generally, snakes can cause nerve and tissue damage, as well as disfigurement. Smaller snakes can cause infection and serious allergic reactions.\n\nSymptoms of snake bites:\n\nImmediate response: Severe fright and mental agitation leading to tachycardia, sweating, hypotension and even vascular collapse are prominent features soon after the snake bite. These nonspecific symptoms may be seen in all snakes bites. \n\nLocal reactions: Local reactions are more prominent in the case of viper bites and less so in others. Intense pain, swelling and violaceous discoloration develop within minutes and often serosanguinous fluid exudes from the fang marks. \n\nGeneral Effects: These vary with the types of snake. Cobra and krait venom are predominantly neurotoxic, while those of vipers are histotoxic (poisonous to body tissues). \n\nCobra and Krait bites: Soon after the byte, the patient complains of a sinking feeling, drowsiness, blurring of vision, diplopia. Dysphagia and dyspnea.\n\nViper Bites: with in 3 to 4 hours of the bite, the hemorrhagic manifestation appear in the nature of extensive bruising, bleeding from the bitten part and injection sites, bleeding from the gums.\n\nSea snake bites: sea snake bites are identified by the victims as sharp pricks. The local reaction may be insignificant. Signs occur with in one hour and initial symptoms consist of pain and stiffness of the muscles of neck, back and proximal parts of the limbs but rapidly becoming generalized.

You didn't say if they survived.  \n\nThe Many Banded Krait has the most toxic venom.

In Africa they are represented by 69 genera and about 360 species. if i knew what kind i could be more specify Try these web pages.\nhttp://www.scienceinafrica.co.za/2004/november/crabspider.htm\nhttp://www.spiderroom.info/va_crabspider.html\nhttp://www.dcn.davis.ca.us/go/anhance/science/spider.html\nhttp://en.wikipedia.org/wiki/Spiders_having_medically_significant_venom\nhttp://www.afpmb.org/pubs/Field_Guide/field_guide.htm

Whether you believe it or not, THE DADDY-LONG LEGS. It's venom is 10x more potent then the black widow or the brown recluse.  Why don't we think so?  Because it's mouth is to small to bite humans.  IT'S TRUE.

not sure..but you should definitely read the book "Salvation on Sand Mountain" by Dennis Covington.  It talks about snake handling and it's a very good book.

It depends upon the snake. They usually can move at about 20 mph when frightened.

The deadliest and most venomous snake is without a doubt the Rhinocerous Viper of Africa. Man, that thing is SOOO colorful! Looks nice, but it is DANGEROUS. Watch out for it next time you visit Africa! \n\nGold is impossible to decompose, by the way.

Of course! Venom can be used to make vaccine! This can be useful for those people have high risk of contacting snake bite.\n\nAlso, blood pressure lowering drug, Angiotensin Converting Enzyme (ACE) inhibitor was developed based on the observation of blood pressure dropping effect after being bitten by snake.As a result, an analogue molecule was developed rationally

neurotoxins and hemotoxins\n\nAlmost all venoms are composed of approximately 90% proteins. Two general types of toxins are known, neurotoxins and hemotoxins. Neurotoxic venom attacks the victim's central nervous system and usually result in heart failure and/or breathing difficulties. Cobras, mambas, sea snakes, kraits and coral snakes are examples of snakes that contain mainly neurotoxic venom. Hemotoxic venom attacks the circulatory system and muscle tissue causing excessive scarring, gangrene, permanent disuse of motor skills, and sometimes leads to amputation of the affected area. The Viperidae family such as rattlesnakes, copperheads, and cottomouths are good examples of snakes that employ mostly hemotoxic venom. Some snakes contain venom that contains combinations of both neurotoxins and hemotoxins. \nThere are approximately 20 types of toxic enzymes found in snake poisons throughout the world known to man. Although no venomous snake has all of these toxins, most snakes employ between six to twelve of these enzymes in their venom. Each of these enzymes has its own special function. Some aid in the digestive process, while others specialize in paralizing the prey. Scientists believe they have identified the following chemicals from snake venom and the specific purpose of each as follows:\n\ncholinesterase; attacks the nervous system, relaxing muscles to the point where the victim has very little control. \namino acid oxidase; plays a part in digestion and the triggering of other enzymes, (is responsible for venom's characteristic light yellowish coloring.) \nhyaluronidase; causes other enzymes to be absorbed more rapidly by the victim. \nproteinase; plays a large part in the digestive process, breaking down tissues at an accelerated rate. (causes extensive tissue damage in human victims) \nadenosine triphosphatase; believed to be one of the central agents resulting in the shock of the victim and immobilizing smaller prey. (probably present in most snakes.) \nphosphodiesterase; accounts for the negative cardiac reactions in victims, most notably a rapid drop in blood pressure.\nThese are only a few of the enzymes found in the chemistry of snake venom known today. Other enzymes have been isolated and identified but their purpose is still largely a mystery to science.

Mamba\nGreen mamba & Black mamba. \nThese are venomous arboreal snakes of tropical Africa\n\nAm I right Sir?

trust me, im a female who has been bitten by a rattlesnake,  the snake will more often kill you for no reason (i was lucky not to die) then a woman will,,, in fact most women wont kill you, even for a good reason !!

From http://en.wikipedia.org/wiki/Venomous_mammals\n\nVENOMOUS MAMMALS INCLUDE:\n-Cuban Solenodon (Atopogale cubana) & Haitian Solenodon (Solenodon paradoxus):  These animals look similar to big hedgehogs with no coat of spines. They both have venomous bites; the venom is delivered from modified salivary glands via grooves in their second lower incisors.\n\n-Platypus (Ornithorhyncus anatinus) (but you know this already): Males have a venomous spur on their hind legs. Echidnas, the other monotremes, have spurs but no functional venom glands.\n\n- Northern Short-tailed Shrew (Blarina brevicauda) & Eurasian water shrew (Neomys fodiens):\n\nVENOMOUS/POISONOUS MAMMALS INCLUDE:\nSlow loris (Nycticebus coucang): Glands on the inside of their elbows secrete a toxin that smells like sweaty socks. They cover their babies in the toxin to protect them from predators, and put it in their mouths to give themselves a venomous bite, delivering the toxin via their lower incisors.

1) Centipede:  Are venomous, predatory terrestrial arthropods.  Some species are highly venomous with extremely toxic venom on their claws which can cause death in humans.\n\n2) Millipede:  Many species emit somewhat poisonous liquid secretion or hydrogen cyanide gas through microscopic pores along the sides of their bodies as a secondary defense. \n\nAs far as humans are concerned, this chemical brew is fairly harmless, although it should never be eaten or applied to the eyes.\n\nHope these answer will help U...
