Coastal Taipan vs. Black Mamba

The coastal taipan and the black mamba snake have several things in common. One of the first similarities between them is they both have potent venom. Plus, they both have rodents including mice and rats in their diet. One difference there is the black mamba’s diet includes bats.

Another similarity between these snakes is they are active during the day. In addition, conservationists list both snakes as Least Concern with stable populations.

With all of those similarities, there are some notable differences between these two snakes. One difference relates to where they live. While coastal taipan snakes live in Australia and Papua New Guinea, black mambas live in Africa.

Coastal taipan snakes can be as long as 9.5 feet but are usually around six feet. Alternatively, the typical size of a black mamba is around seven feet long. So, when you look at average size, the black mamba is the winner in that category.

One of the most intriguing facts about a black mamba has to do with the interior of its mouth. It’s black which is unusual for a snake. So, the inside of this snake’s dark mouth is only seen by prey or a human who has an unfortunate encounter with this reptile!

Biologists report the venom of a black mamba is so dangerous it results in death 100 percent of the time if the bite goes untreated. This is the same for coastal taipan snakes. However, deaths as a result of a coastal taipan’s bite are rare due to an effective, readily available antivenom.

Doctors suggest there are more deaths from a black mamba’s bite because of the difficulty of getting the injured person to the hospital in a timely way. Though there is an antivenom for the black mamba’s bite, not all hospitals in Africa have it available to patients.

Coastal Taipan Venom: How Dangerous Are They?

The bite of a coastal taipan is extremely venomous. Keep in mind these snakes want to avoid encounters with humans but will strike if they feel trapped or are stepped on.

A person who is bitten must be taken to the hospital for antivenom immediately. Dizziness, convulsions, nausea, and other symptoms start quickly after a bite.

While waiting for an ambulance, put a pressure bandage on the bite wound and make a splint to keep the limb immobile. Try to keep the person as still and calm as possible.

Coastal Taipan Behavior and Humans

Despite having potent venom, coastal taipan snakes are known to retreat from potential encounters with humans. People are bitten usually because they accidentally step on this snake or reach into an area without noticing its presence.
