Why Are There Many Poisonous Animals in Australia? Here's the Reason

"Why Are There Many Poisonous Animals in Australia? Here's the Reason"

Australia is home to a variety of venomous creatures such as spiders, snakes, jellyfish, octopuses, ants, bees, and even the platypus. However, why do so many animals in Australia use these biological weapons? Many of these small creatures have been in Australia since the time the continent was formed. However, unlike venomous snakes, which arrived after the continent was formed.

"As information, 100 million years ago, Australia became a continent that was separated when it broke away from the southern supercontinent Gondwana, said Kevin Arbuckle, a professor at Swansea University, England. This caused the lineage of 'venomous' insects to be 2-3 times older than that separation."

Why Are There Many Poisonous Animals in Australia? Here's the Reason

"Some species that have already become 'venomous' were only confined to Australia when the continent became isolated."

The venomous arthropods there include trap-jaw ants (genus Odontomachus), which can deliver a painful bite.

"Similarly, the Australian bulldog ant (genus Myrmecia), which can sting and bite simultaneously, is considered one of the deadliest ants in the world and is reported to have killed three people since 1936, according to Guinness World Records. The lineage of this venomous ant has existed in Gondwana at the time of separation and remained there after Australia became a separate continent."

The translation of "Laba-Laba Funnel-web" to English is "Funnel-web Spider."

The funnel-web spider (genus Hadronyche and Atrax) is the only type of spider that exclusively originates from Australia, capable of killing humans with its venomous bite, Arbuckle stated. This animal is suspected to have killed 13 people, although there have been no recorded human deaths since the antivenom serum was introduced in 1981, according to the Australian Museum.

"A type of widow spider from Australia, the redback (Latrodectus hasselti), can also kill with its venomous bite."

"Their ancestors were also there before Australia became a separate continent."

Already Existed Before the Continent of Australia Stood Alone.

"Similarly, venomous cephalopods, including squids, octopuses, and cuttlefish, have existed for 300 million years. They have lived in the surrounding waters long before Australia became a standalone continent."

"The shift of the continents pushed Australia across the cold South Pole, leading to the extinction of most reptiles there. As the continent gradually moved north, the temperature became warmer and attracted reptiles back. After 40 years had passed, the first snakes to inhabit this continent belonged to the Elapidae family with venomous fangs at the front, including cobras, mambas, coral snakes, and taipans. They became the ancestors of snakes, which then evolved into more venomous snakes."

The translation of "Ubur-Ubur 'Berbisa'" to English is "Jellyfish 'Venomous'".

"Regarding jellyfish, each species has venom. They also have a history of over 500 million years and have been drifting in the oceans since before Australia existed. Although the deadly box jellyfish (such as Carukia barnesi) and Portuguese man o' war (Physalia physalis) are found in Australian waters, Arbuckle emphasizes that these creatures inhabit tropical and subtropical waters, not just in the Australian region."

The coastline of Australia creates an ecosystem that is suitable for these creatures. Counting how many venomous creatures inhabit Australia is quite difficult.

"Dieter Hochuli, a professor of ecology at the University of Sydney."

"Nevertheless, Arbuckle argues that the venomous fauna in Australia is actually still within a typical range, except for snakes. "Contrary to popular belief, Australia is not particularly rich or diverse in venomous invertebrates," "Australia has a very enduring and prominent image as a home for highly venomous animals, yet much of this is exaggerated.""

He wondered whether part of this belief came from the continent's "scientific capital" and "very good infrastructure" for public health and medical care.

"The diversity of venomous animals is not at all unusual for an area that is mostly tropical,"
The translation of "kata Arbuckle." to English is "word Arbuckle."
