Coral Snake Appearance: There are many varieties of coral snakes throughout the Americas, but we will address the USA snakes. The most common species in the United States have a universal red-yellow-black-yellow pattern. Not all coral snakes have the same color scheme, so it is important to be familiar with the snakes specific to your region. This snake is small in comparison to other venomous snakes in the United States. At its longest, an adult can measure around thirty inches. The colorful body is slender and lacks real variance in width. The head blends seamlessly into the body with no distinctive neck. The head of this species of coral snake is always black. 

Coral Snake Habitat and Behavior: There are two types, the Eastern Coral Snake, and the Western Coral Snake. The Eastern is more common, but neither is seen often, because Coral snakes that live in either the southeastern or southwestern United States prefer wooded, marshy, and loose-soiled areas often under debris. They are very reclusive, staying in the safety of underground burrows or dens during the day and emerging in the evening and early morning to feed. Among their own kind, coral snakes are solitary, showing aggression even during breeding.


Unlike other venomous snakes, the coral snake has round pupils, a blunt head, and no heat sensing pits. Its venom sacks are not attached to the fangs but are adjacent to the teeth, permeating the puncture holes as the snake latches onto a victim. Contrary to common belief, the maximum amount of venom can be delivered without chewing; the venom delivery is related to the duration of time the snake is attached, not how many times it bites its prey. Multiple bites do facilitate quicker venom transfer, but do not necessarily affect the quantity. 

Coral snake venom is neurotoxic, another fact which distinguishes it from other North American poisonous snakes. Neurotoxic venom affects the way the brain communicates with muscles, slurring speech, affecting movement, and ultimately ceasing cardiac or respiratory function. A bite from a coral snake can go without symptoms for as long as twelve hours.

Unfortunately, due to their bright colors, coral snakes are a favorite of children. Many of the reported bite cases are due to the curiosity of a young person who tried to pick up the reptile. For this reason, it is good that coral snakes are shy and rarely spotted. To avoid trouble, read more about the Snake Rhyme Poem, and information about the Coral Snake Look Alikes, such as the Scarlet Kingsnake, to find out what does a coral snake look like. 

Infant coral snakes hatch from eggs laid by the female snake. Coral snakes do not give birth to live young like many of the other North American venomous snakes. Once born, coral snakes are seven inches long and are already at their full venomous potential. 

Coral Snake Diet: Coral snakes are carnivorous and like a diet of other reptiles and snakes (even other coral snakes). It will occasionally feed on frogs. 

Coral Snake Facts:
Coral snakes are often confused with some non-venomous snakes of similar coloration. The milk snake and scarlet kingsnake have similar colors but in different patterns.
Coral snakes are the only venomous snake in North America that is not a pit viper.
Coral snakes are related to mambas, cobras, and sea snakes.
A variety of rhymes have been developed to properly identify a coral snake. “Red on yellow, kill a fellow. Red on black, friend of Jack” is just one variation.
No deaths from a coral snake bite have been reported since 1967 when the antivenin was developed.
The life expectancy of a coral snake in the wild is unknown. In captivity, the snakes will live as long as seven years.
The fangs of the coral snake cannot be flatted against the roof of the mouth. They are permanently erect.
Coral snakes around the world come in all varieties of colors from blue and red to black with bright yellow spots.
Coral snakes are named for the bright, underwater coral explorers discovered along the coasts of the New World.
When it is threatened, the coral snake will curl up, using its tail in an attempt to confuse the attacker as to which end of the snake is the actual head.
Below are some other species of snake that may look like a Coral Snake:
Scarlet Snake
Red Rat Snake
Scarlet King Snake

If your brain cannot communicate to the heart that it needs to beat, the function will cease. Neurotoxic venom is only found in lethal doses in the coral snake out of the venomous snakes in North America. When the snake bites its victim, it will hold on to the adversary for as long as possible. This is because coral snakes do not have venom sacks attached to their fangs like vipers do. The coral snake’s venom is secreted into the wound as the snake holds on. The longer the animal is attached, the more venom is administered. Coral snake bites can go without symptoms for as long as twelve hours after exposure. Some people who are bitten believe they have encountered a milk snake and not a coral snake because no immediate signs are evident. Thankfully, despite the delayed onset of issues, no reported deaths from coral snakes have occurred since the development of an antivenin in 1960.

Coral snakes habitat Coral snakes live in the southeastern and southwestern United States, though there are other species of coral snakes around the world. They prefer wooded areas, marshes, or places with loose soil. Preferring to hunt in the evening or early morning, coral snakes remain in their dens for the majority of the day. For this reason they are rarely spotted by travelers. Unlike many other snakes, the coral snake is not bold and will try to flee a situation rather than stand its ground. If the animal feels harassed, however, it will strike without warning. The bite from a coral snake is not like the bite from a pit viper. Coral snakes will hold on to their victim, allowing the venom in their mouths to transfer into the wound. The longer the snake holds on, the more venom is put into the body. This substance is a neurotoxin and will eventually cease cardiac and pulmonary activity.

As debate continues over its taxonomic identity, there’s no doubting the Mulga Snake’s status as one of Australia’s most formidable snakes.

Standard Common Name
Mulga Snake

Alternative Name/s
King Brown Snake

Number of species
A number of new species of mulga snake have been proposed, however at present only one species is universally recognised, Pseudechis australis. Recent molecular studies have lent support to the identification of a number of cryptic species within P. australis.

Identification

Juvenile snakes may be of average built but adults are usually quite robust, with a broad deep head and bulbous cheeks. The scales on the back, sides and tail are usually two-toned; a darker colour covers the distal portion of the scale to various degrees (from just the very tip to almost the entire scale) and may be brown, reddish brown, coppery brown or brownish black. The base of the scale is usually yellowish white to greenish yellow, contrasting with the darker colour to produce a reticulated effect. Individuals from the far northern arid areas have almost no darker pigment whereas southern populations are almost black. The tail is usually darker than the body and the top of the head is a uniform colour similar to the dark of the body scales. The eyes are relatively small with a pale reddish brown iris. The belly is cream to salmon-coloured, and often has scattered orange blotches.

Mid body scales in 17 rows, ventrals 185-225, anal scale divided, subcaudals single anteriorly and divided posteriorly (occasionally all single).

Size range

The largest specimen reliably measured was an individual from near Darwin that measured 3.3 m in total length. However they generally average around 200cm (total length). Among adult specimens in museum collections, mean snout-vent lengths are significantly larger in males than in females.

Similar Species

With its wide distribution the Mulga Snake overlaps with a number of other similar-looking elapids, particularly species of brown snake Pseudonaja spp., and other members of its own genus Pseudechis, e.g. the Spotted Mulga Snake Pseudechis butleri.

Distribution

Mulga Snakes have the widest distribution of any snake species in Australia, ranging throughout the continent except for the extreme southern and general southeastern parts.

Also found in south-eastern Irian Jaya, and possibly western Papua New Guinea.

WHAT DOES THIS MEAN?

Habitat

The species occurs in a wide variety of habitats, from closed tropical mosoon forest to Triodia hummock grassland, chenopod shrubland and almost bare gibber or sandy desert. Mulga Snakes may also occur in highly disturbed areas such as wheat fields. They shelter in disused animal burrows, in deep soil cracks, under fallen timber and large rocks, and in deep crevices and rock cavities in outcrops.

Seasonality
Southern specimens that are typically darker coloured have been observed basking in winter.

Feeding and Diet

In the wild, Mulga Snakes feed on a wide variety of vertebrate prey, including frogs, reptiles, reptile eggs, bird eggs, birds and mammals. The species also occasionally eats invertebrates and carrion.

Mulga Snakes are apparently immune to the venom of at least one of their snake prey, the Western Brown Snake Pseudonaja nuchalis, and show no ill-effects when bitten by their own species. Unfortunately the Mulga Snake is not immune to the toxic Cane Toad, which is thought to have led to the snake’s decline in some northern parts of its range.

Other behaviours and adaptations
The species may be active both during the day and night (according to temperature), with diminished activity during mid-day and between midnight to dawn. During the hottest months, particularly in the northern parts of their range, Mulga Snakes become most active in the late evening and early hours after dusk.

Life history modes
crepuscular, diurnal, nocturnal, terrestrial

WHAT DOES THIS MEAN?

Life cycle
Male combat has been recording in early-mid spring for this species. The males entwine their bodies and with their raised heads attempt to push over their opponent.

In southwestern Australia, mating has been recorded in early spring, and in Eyre Peninsula in mid-spring. In a survey of specimens in all the major Australian museums, females with yolking follicles had been collected between mid-winter and late spring, and females carrying oviducal eggs were from mid-summer, mid- autumn and early spring. In northern populations breeding may be aseasonal or associated with the wet and post-wet season. The time between the last courtship/mating and egg-laying varies from 39 to 42 days. Clutch sizes range from 4 to 19, with an average of around 9. There is a significant positive relationship between the snout-vent length of the female and clutch size.

The eggs may take between 70 and 100 days to hatch, depending on the incubation temperature. There has been a case where two hatchlings emerged from one egg - the egg was normal sized but the hatchlings were about half the size of their clutch mates. 


Predators, Parasites and Diseases
Large Mulga Snakes have few enemies, however small specimens may fall victim to birds of prey.

The species' known endoparasites include nematodes. Older specimens often carry a high burden of ticks.


Conservation Status
Not listed as threatened.

Danger to humans and first aid
The temperament of the Mulga Snake appears to vary with locality. In southern areas of Eyre Peninsula and west coast of South Australia it is a shy, quiet snake, however northern specimens are reported to be quite excitable when disturbed.

When threatened, the Mulga Snake inflates its body and holds its head and flattened neck in a wide curve parallel to the ground. It will throw its head and neck from side to side, hissing loudly as it does. If pressed further it will lash out wildly in an attempt to bite. Mulga Snakes bite savagely and may hang on and chew as they inject their venom. The venom is highly toxic and can be expressed in enormous quantities. Its effects are mainly haemolytic (breaks down blood cells), cytotoxic (disrupts cells), myotoxic (affects muscle), and also mildly neurotoxic (affects nerve cells). Anyone suspected of being bitten should seek immediate medical attention. Should antivenom be required it is important to note that despite the alternative common name of King Brown Snake, the Mulga Snake is in fact a member of the black snake genus Pseudechis, therefore Black Snake Antivenom will be necessary.
