Story of the cup and snake as symbol of pharmacy?
The cup with a snake coiled around it is called the bowl of Hygeia with the serpent of Epidaurus, and is a variant on the above. Hygeia was Aesculapius's daughter and a Greek Goddess of health. Her symbol was a serpent drinking from a bowl. The vessel is usually depicted with a long stem and a shallow, wide bowl as seen here. It also is considered suitable for pharmacy. The bowl of Hygeia with serpent of Epidaurus shown here is the symbol for Hungarian pharmacists.
What is snake's biting mechanism?
There are two types of snakes-
Poisonous & Non-poisonous
ØBoth snakes bite.ØNon-Poisonous snakes have no apparatus for biting ,so no serious harmØPoisonous snakes have poison apparatus for biting, so serious harm These poison apparatus are- a pair of poison glands poison ducts fangs
POISON GLANDS
one pair of poison glands
each one is situated on either side of the upper jaw.
The poison glands are actually the parotid glands.
Each poison gland is sac like in appearance.
They are held in position by some ligaments.
With the help of anterior ligament, the gland is attached with the maxilla.
The posterior ligament is present between the gland and the quadrate.
In addition to these, fan-shaped ligaments are also situated between the side walls and squamoso-quadrate junction.
Poison duct
Each poison gland is provided with a narrow duct at its anterior portion
passes along the side of the upper jaw, loops over itself and
finally opens at the base of the fang.
Fang
one pair of fangs in the upper jaw.
They are enlarged maxillary teeth
are very sharp and pointed.
There is great power of regeneration (when lost for some reason).
On the basis of structure and position, the fangs are of the following types :
Proteroglyphous
Stenoglyphous
Opisthoglyphous
Aglyphous
1)Proteroglyphous type: The fangs are comparatively small and they are present in front of the maxillae. The fang has a groove all along its anterior face. Examples : Cobra, Krait, Sea snakes and Coral snakes.

2)Stenoglyphous type: The fangs are movable and turned inside. Poison canal runs through the fang and opens at the tip. Examples: Vipers and Rattle snakes.
3)
3)Opisthoglyphous type. The fangs are small and lie at the back portion of maxillae. The fang has a groove along its posterior face. Examples : Some colubrid snake (African tree snakes)

Associated bones and muscles
There are some important bones and muscles which are directly or indirectly associated with the mechanism of biting. In the skull, maxillae, quadrate, pterygoid, squamosals, ectopterygoids and palatines are movably articulated. Premaxillae are very much reduced.
Sqamosals are loosely attached tocranium. The joint of quadrate and lower jaws acts as fulcrum. Quadrates are also loosely articulated with the cranium, pterygoid and lower jaw. Ectopterygoid is a transverse bone.
The important muscles are Digastric muscle, Anterior and Posterior temporalis muscles and Protractor-Pterygoid or Sphenopterygoid muscle. In addition to these, there are two more muscles associated with the poison glands. These are masseter muscle and Mandibular constrictor muscle.
The gastric muscle is attached with the squamosal bone anteriorly and with the base of the lower jaw (articular) posteriorly.
The Sphenopterygoid muscle is attached to the Sphenoidal region anteriorly and dorsal surface of the Pterygoid posteriorly. Anterior and Posterior temporalis muscles are attached to the side walls of the cranium and the lower jaw.
Biting mechanism in snake
The skulls of poisonous snake are very flexible, so they can make a considerable degree of adjustment during biting.
In cobras, the fangs are erect, but in vipers the fangs are lie against the roof of mouth when closed. So biting mechanism contains two steps:
1. Erection of fangs
-contraction of digastric muscle lower the mandible & the mouth opens.
-lower end of quadrate pushes forward. This in turns pushes forward of pterygoid. This is also aided by the contraction of sphenopterygoid muscles.
- The forward pull of pterygoid leads to the upward push of ectopterygoid.
-This causes maxilla bearing fangs to rotate through 90o at hinge-joint with lacrimal . As a result the fangs become erect.
2. Injection of poison
-Simultaneous stretching of constrictor muscles around poison gland, forces its poison through poison duct into canal or groove of fangs to be injected into the victim.
-When the mouth is closed by the contraction of temporal muscles, the above movements are reversed. The fangs embed in the prey which is drawn into the mouth. At the same time the vertical fangs rotate to become horizontal.

Do corn snake bites hurt as much as ferret bites?
It depends on how hard the ferret bites which depends on why the ferret has bitten you. If the ferret is scared or you are hurting it, it will bite to defend itself. This bite could be serious and painful. If the ferret is playing (ferrets play rough) will sometimes give you a small bite which isn't very painful.
Ferrets can be trained to not bite or nip during play by scuffing them when they bite as this tells them you didn't like the behaviour. You can also get spray to put on your hands which will teach the ferret that your skin tastes bad and so will discourage biting
What happens to a snake when a vehicle runs over it?

No. Snakes are usually given one or two food animals (usually mice or rats depending on the snake). It is recommended by some that a snake be fed in a separate contain to avoid it accidentlly ingesting bedding.
I have both males and females in my vast reptiles collection.
The dried meat of the cocoanut, from which cocoanut oil is expressed.
There is no general answer. Every encounter is unique. In some cases the dog wins. In others, the dog will die due to a venomous bite; or he becomes the snake's next meal.
Dogs and cats regularly kill snakes, but some face larger or more dangerous reptiles than they can handle.

A:
(If bitten and venom is injected)
The most venomous snake on earth is the Belcher's Sea Snake (Hydrophis Belcheri) or the Faint Banded Sea Snake, some consider the Inland Taipan (Oxyuranus microlepidotus) an/or the Beaked Sea Snake (Enhydrina schistosa) to be the most toxic, however, with recent and more accurate studies as of 2010 prove the Belcheri has a 100 times more toxic venom then the two above or any other snake on earth.
It has a paddle-like tail, breathes air and can hold it's breath up to 8 hours, a few milligrams of venom can kill over a thousand people.
It's habitat has a wide range in the South Pacific.
Excluding the Belcher's Sea Snake the next most venomous snakes on earth according to their venom rating are:
2- Inland Tiapan (Oxyuranus Microlepidotus).
3- Common Indian Krait (Bungarus Caeruleus).
4- Philippine Cobra (Naja Philippinensis).
5- King Cobra (Ophiophagus Hanna).
6- Russell's Viper (Vipera Russellii).
7- Black Mamba (Dendroaspis Polylepis).
8- Yellow Jawed Tommygoff (Bothrops Asper).
9- Multibanded krait (Bungarus Multicinctus).
10- Tigar Snake (Notechis Scutatus).
11- Jararacussu (Bothrops Jararacussu).

What type of snake's month is white when opened?
The Cottonmouth - a highly-venomous species from south-east america.
Does eating a poisoned prey harm the snake?
No. The reason for this is because snake venom is made of amino acids and proteins which get broken down rapidly by the digestive acids in snakes, people, and other animals. snake venom is only toxic if it gets into the blood stream.
There are snakes on every continent except Antarctica. Of course snakes are in Borneo, it's tropical rain forest.
What do eyelash vipers look like?
Eyelash viper adults rang from 55-82 cm (22-32 in) long. Females are longer and more variable in size than males. They have a wide, triangular-shaped head, and eyeswith vertical pupils. Like all pit vipers, they are solenoglyphous, having large, hypodermic needle-like fangs in the upper jaw that fold back when not in use, and have heat sensitive organs, or pits, located on either side of the head between the eye and nostril.
Its most distinguishing feature, and origin of its common name, is the set of modified scales over the eyes that look much like eyelashes. The eyelashes are thought to aid in camouflage, breaking up the snake's outline among the foliage where it hides. Eyelash vipers occur in a wide range of colors, including red, yellow, brown, green, even pink, as well as various combinations of those colors. They often have black or brown speckling on the base color.
Who would win a fight out of a protective snake king snake or a cobra?
The cobras generally have a much more potent venom than rattlesnakes. However, there are other snakes, such as the saw-scaled viper and Russell's viper, which are even deadlier. Sea snakes are even more potent but are rare to bite.
