The long-tailed planigale is a fascinating creature that's native to Australia. It's one of the smallest marsupials in the world, weighing in at just 6 grams.
These tiny animals are nocturnal, meaning they're most active at night. They have large eyes that help them navigate in the dark.
The long-tailed planigale is a carnivore, feeding on small insects and other invertebrates. Its diet consists mainly of ants and other tiny creatures.

Classification
The long-tailed planigale is a part of the Dasyuridae family, which is a group of carnivorous marsupials.
The species was first described by Oldfield Thomas in 1906 and was initially placed in the genus Phascogale.
The long-tailed planigale is a member of the Planigalinae subfamily, which is a subgroup of the Dasyuridae family.
It's worth noting that there has been some taxonomic confusion regarding the long-tailed planigale, with some sources referring to it as Planigale subtilissima.
Currently, there are three recognized subspecies of the long-tailed planigale, which are listed below:
The long-tailed planigale's classification is as follows:
Subclass: Theria
Infraclass: Marsupialia
Superorder: Australidelphia
Order: Dasyuromorphia
Physical Characteristics
The long-tailed planigale's head shape is truly unique. It's flattened and much broader than it is deep, measuring only 3 to 4 mm from top to bottom.
This unusual shape allows the planigale to squeeze into tiny soil cracks. It's an essential adaptation for finding prey and avoiding predators in its harsh environment.
The long-tailed planigale's body is similar to a small mouse's, with a pointed muzzle and variable brown fur. Its hindlegs are slightly larger than its forelegs.
The average combined head-body length of a long-tailed planigale is around 59 mm, with a similar tail length.

Reproduction and Life Cycle
Breeding can take place at any time of year, but mostly during the wet season.
The long-tailed planigale can have a large litter, with four to eight young born, and in some southern populations, as many as 12.
The young spend six weeks in the backward-facing pouch, where they receive nourishment and protection.
After leaving the pouch, the young stay hidden in a grassy nest under bark or other vegetation for about another six weeks.
During this time, the mother forages each night, leaving the young to fend for themselves.
Habitat and Distribution

The long-tailed planigale is a small but fierce marsupial that calls northern Australia home. It can be found in a variety of habitats, including floodplains, savannah woodlands, and riparian areas.
Its preferred habitats are characterized by cracked clay soils and blacksoil plains. The long-tailed planigale is also known to inhabit the Great Sandy Desert and the Kimberley region in Western Australia.
The long-tailed planigale's range spans across northern Australia, from the Pilbara in Western Australia to the Barkly Tableland in the Northern Territory and Townsville in Queensland.
Here's a breakdown of its preferred habitats:
These habitats provide the long-tailed planigale with the perfect environment to hunt, hide, and thrive.
Behavior and Diet
The long-tailed planigale is a nocturnal animal, so it's no surprise that it's most active at night. It has poor eyesight, but its keen sense of smell and hearing make up for it.
These small marsupials are omnivores, which means they eat both plants and animals. They have a varied diet that includes insects, small reptiles, and even small mammals.

Their diet is also influenced by their geographic location, with those living in areas with more vegetation eating more plant matter. In contrast, those in drier areas tend to eat more insects and small animals.
Their ability to survive on a wide range of food sources is likely an adaptation to their unpredictable environment. This flexibility allows them to thrive in different habitats.
Planigale Overview
The Long-tailed Planigale is the smallest of all marsupials, and one of the smallest mammals in the world. It's a common inhabitant of Australia's Top End, found in blacksoil plains, clay-soiled woodlands, and seasonally flooded grasslands.
They are carnivores, living on invertebrates and small vertebrates which they catch by energetic nocturnal hunting through leaf litter and in soil cracks. Their diet consists of insects and their larvae, small lizards, and young mammals almost as large as themselves.
Here's a breakdown of their physical characteristics:
Their head shape is quite unique, allowing them to squeeze into the tiniest of soil cracks. This is likely due to the clays and blacksoils of the Top End developing deep cracks as they dry after the monsoonal summer rains.
Original Name

The original name of the Planigale is Planigale maculata, but it's also referred to as the spotted planigale.
This small marsupial was first described by naturalist George Robert Waterhouse in 1838.
Type Material
Planigales are small, carnivorous marsupials that belong to the dasyurid family. They are native to Australia.
These tiny predators have a unique type of material that makes up their fur. The fur of planigales is soft and dense, with a woolly texture.
Their fur is also highly specialized, with a dense undercoat that helps to keep them warm in cold temperatures. It's a great adaptation for a small animal that's active at night.
Planigales have a distinctive type of fur that's often compared to a thick, velvety carpet. This soft and luxurious texture helps to keep them warm and cozy in their underground burrows.
Their fur is also highly water-repellent, which is a useful adaptation for an animal that spends a lot of time underground and in wet environments.
Validity Status

The Planigale is a small, carnivorous marsupial native to Australia. They are known for their unique appearance and habits.
Planigales are nocturnal animals, meaning they are most active at night. They have poor eyesight, but a keen sense of smell and hearing.
Planigales are solitary animals and have large home ranges, which they mark with scent to keep other Planigales away. They are generally non-aggressive and only come together during mating season.
Planigales are carnivores and feed on small insects, worms, and other invertebrates. They use their long, pointed snout to sniff out prey.
First The Stats
The Planigale is a tiny creature, with a scientific name that's just as unique: Planigale ingrami. Its weight can reach up to 0.22 ounces, which is roughly the weight of a paper clip.
This little guy's length is quite impressive for its size, reaching up to 2.32 inches, and it's got an extra 3 inches of tail to boot.

Planigale

The Long-tailed Planigale is the smallest of all marsupials, and one of the smallest of all mammals, reaching a combined head-body length of 55 to 65 mm.
They are carnivores, living on invertebrates and small vertebrates which they catch by energetic nocturnal hunting through leaf litter and in soil cracks.
In the wild, they can be found in the blacksoil plains, clay-soiled woodlands, and seasonally flooded grasslands of Australia's Top End.
Their head shape is extraordinary, with a flattened head that's much broader than it is deep, allowing them to squeeze into the tiniest of soil cracks.
The skull is one-fifth as deep as it is wide, making it perfect for navigating through narrow spaces in search of food or shelter.
Here are some key stats about the Long-tailed Planigale:
They have a pointed muzzle, nondescript and variable brown fur, and hindlegs a little bigger than the forelegs, allowing them to stand semi-crouched on hindlegs and tail.
Breeding can take place at any time of year, but mostly during the wet season, with four to eight young born per litter.
More to Come
As we've explored the fascinating world of planigales, it's clear that there's still much to learn about these unique animals.
Planigales are found in the wild in Australia, specifically in the eastern and southern regions.
Their diet consists mainly of insects, spiders, and other small invertebrates.
One of the most interesting aspects of planigales is their ability to survive in a variety of environments, from forests to deserts.
These small marsupials are also known to be solitary animals, only coming together for mating.
Biogeography
The long-tailed planigale is found in Australia, specifically in the eastern and central regions. Its distribution is restricted to the arid and semi-arid zones.
This small marsupial is adapted to living in a variety of habitats, including grasslands, savannas, and open woodlands.
