Lest Concern

One of the Deadliest Snakes!

The coastal or eastern taipan is considered to be one of the deadliest species of snake in Australia though deaths have reduced in number since the introduction of an effective anti-venom in 1956.

This species is a carnivore which will prey on a range of small mammals, birds and reptiles. They have benifitied from the introduction of rats and mice to Australia as these have provided an additional food source.

Appearance

What does a Coastal Taipan look like?

The coastal taipan is the largest species of venomous snake in Australia. Their length may reach up to 3.5m (11.5ft) long and weigh up to 5kg (11lbs). Males have a slightly larger body than the females.

They have a moderate or slender body. Their head is large and long with an angular brow. The eye features an orange-brown iris and a round black pupil.

Their body is covered by keeled scales which are colored tan or yellowish, blackish or reddish brown. On the underside they are cream with orange spots. Across the face and snout they have a cream flush. This may darken as they age but the snout remains pale.

The coloration of a coastal taipan is slightly variable across the seasons.

Coastal taipans have a similar appearance to the related eastern brown snake and they are often confused for this species.

Adaptations

How does the Coastal Taipan in its habitat?


The coastal taipan possesses a strong neurotoxic venom and is considered to be the third most venomous land snake found in Australia. This serves to quickly immobilize their prey. By doing this they reduce the risk of the prey item potentially injuring them by fighting back.

Diet

What does a Coastal Taipan eat?

Coastal taipans are carnivores. Their diet includes mammals such as rodents, bandicoots and quolls. They will also feed on birds with reptiles such as lizards also being eaten. Food is swallowed whole.


Their food sources have expanded with the introduction of domestic rats and mice.


Due to the large size of the prey items they consume they may only need to eat a few times each year.


Food is struck quickly and injected with their potent venom. They will then release the prey and wait till it dies. This reduces the risk that they are attacked by the prey item.


Their venom comprises two parts. One acts on the nervous system to stop the muscles from working while the other prevents the blood from clotting so they bleed to death.


They can sense their food by flicking out the tongue which captures scents that are then processed by the Jacobson’s organ on the roof of their mouth.

Range

Where do you the Coastal Taipan?

Australia and New Guinea are the native home of the coastal taipan. As their name suggests they are found along the coast of Australia from Western Australia across the Northern Territory and Queensland down to New South Wales.

Habitat

Where can a Coastal Taipan survive?

They can be found in a wide variety of habitats including rainforests, sclerophyll forest, woodlands, grassy paddocks and sand dunes.


With the expansion of human habitations they may be found in cane fields or rubbish tips.


Coastal taipans will shelter in an abandoned burrow, hollow log or piles of vegetation.

Reproduction

How does a Coastal Taipan produce its young?

Mating can occur anytime between March and December with gravid females spotted during spring.


Males engage in a ritualistic combat display when competing for breeding rights. The pair will coil around one another and work to force the head of their opponent to the ground. These displays may last for hours.


A female will lay between 7 and 20 eggs which are shaped like a pill. These soft shelled eggs are placed in a hollow log, under a tree root or in a ground cavity.


These incubate for an average of 68 days before hatching. The length of the incubation is dependent on the temperature.


Females abandon the nest after laying the eggs and have no involvement in raising their young.


Males will reach sexual maturity at 16 months old while females develop later at 28 months old.

Behaviour

What does the Coastal Taipan do during its day?

Most of their activity occurs at dawn and dusk. When it is extremely warm they will become nocturnal. They are most active in late winter and early spring.

Predators and Threats

What stops the Coastal Taipan from surviving and thriving?

The coastal taipan rarely faces predators as adults. Younger animals will be preyed upon by goannas and birds of prey.


Humans kill them due to the perceived threat to human safety.


Prior to the development of antivenom few people had survived a bite from the coastal taipan. Since this anitvenom was developed in 1956 the number of deaths has been reduced. They are still regarded as one of the most dangerous species in Australia.


Humans catch them to keep in the pet trade.

Quick facts
