Ibises


Hello Reader,


Today anotar bird to talk about. The Ibises.




It is a bird far spread into the world, except in Antarctida, habiting forests, plains and wetlands. But I focusing in two species of ibis, the straw-necked and the australian white ibis.





and




This two species of ibis have the costume of get together in a huge flock on the season of breeding when they coexist. They have a time to normally procreate in the year depending on the region were they are, but have some cases when occur after a big rain in any time of the year. They also can create their nests in a place where other birds like egrets, herons, spoonbills or cormorants, who also build nest near a corp of water.




The most common ibis to see is the australian-white-ibis, because it have adapted well to the live in the city; While the straw-necked ibis don’t have adapted to cities, but have a good relation with farmers sins they eat the plague insects. The australian white ibis is consider in some places a plague in the city due their unique bad smell and they also turn garbage cans and even stole sandwiches of picnic baskets.





The australian white ibis get so long in the city that they even abandon their usual place of procreation to stay in the same place, building their nests in rivers that cross the town.

False stonefish



Hello Reader,




Some fish have biofluorescence, and this one is in the list. Greetings to the false stonefish.









The biofluorescence probably is used in communication with other from the same species, and assist in their camouflage, sins the corals also have biofluorescence.











Unlike the real stonefish who have 13 venomous spines the false stonefish have 12, but still have the dangerous venom. And like the stonefish they wait for the prey came to the range of atack. The false stonefish prefers walking to swimming. Sometimes they even get covered with sediment.

Painted Button-Quails



Hello Reader,


Normali in the animal kingdom you will see a male doing the call for females and protecting a territory, men while the female take care of the offspring. But note this one. They switches places in the chores. I am talking about the Painted Button-Quails (Turnix varius).














The Painted Button-Quails is endemic of Australia.








The female is the one who will keep a territory and have more than one partner. She calls for the males, lay their eggs (between 3-5), and leave the part of caring for the yongs with the male. The female is bigger than the male, and during the courtship she even offer food to the male.



The male will incubate the eggs during 15 day, and will care for them after hatching more 16 days, when they will be group enough to take care from themselves.



It is a bird that aviators created, but is not recommended if you are a total inicant. They can be see like a control pest population of insects.

Stonefish (Synanceia)



Hello Reader,




I bring a thought fish. He can survive out of the water for 24h, have the most deadly venom and you can esly mistake him with a rock.








The stonefish have spines over they back, it is in thous people steps accidentally. They have a tissue that incover the spine, and when that finc in something and the tissue is pushed down squises the venom aut.




The venom of the stone fish is deadly and each of the 13 spines can delivery it, but luckily if you have a water hoten the 45ÂșC you can help diminish the venom. The venom of him is destroyed in high temperature, but it can’t be a temperature that hurt the person. But you still needed to go quickly to receive the antivenom.











The ability of stay out of water for 24h is related to the fact this fish just stay put and wait for they victims. Been stil even if the mare start to goin down and they can get stuck in a pond or even stay in a place where the water retreats totally. How normally in less than 24h the mare get bec, the fish can stay in the same place and just wait, food will came together with the water.

Phocoena dioptrica


Hello Reader,


Looking in a list of marine animals from Australia, I found the Spectacled porpoise.









This creature is found in a good part of the Antarctic Circumpolar Current , and there was a register in south Australia of them.






Infortunately, little is know about this specie of Porpoise, because they run from boats. The majority of registers about the species is from cativets ones. In fact the firth report of this species came from a dead body founded in the shore, in 1912.



What can make you wander, how many exist from this creature? No one know. Exist to little data about them to estimate a population.



They have a easy way to distinguish the male from female by the dorsal fin, the male have it in a biggest size. 






Don’t let their faces trick you. They are related with whales and dolphins, but they are porpoises. Even been close related with dolphins and having small size they are described like been little whales with spade-shaped teeth (dolphins have a conical teeth).

Possum



Hello Reader,




Today will see a common animal from Australia, the Possum.



This marsupial is easy to see and harmless… wel, almost harmless. I heard the relate of these two people who was walking at night and from no wer end no reason a possum just jump and grab the lag of one, who of course scream and shook until the animal run away. But normally they have a calm nature and probably only will attack you if they fell cornered.





Possum are cute animals, don’t mistake them whit opossum, even thow both play death the opossum live in the americas and have a hairless tail, while the possum live in Australia and have a furry tail. The offspring from the opossum is many, when the offspring os the possum is just one. Both have a nocturnal life.









This is an animal that you definitely will see in Australia, because the common brushtail possum live quite well in the city and far spread in Australia, but have a control population duet the vast list of predators. In New Zealand, where they are an introduction species and don’t have natural predators, they become a plague.







Even they diet is based in leafs and fruits, they tried to eat practically a little of everything, but the principal dish is leafs. Of course they don’t refuse a free meal.
