Transcript of Echidna

Short-Beaked Echdinas

britannica school edition
Grzimek's Animal Life
tazmania parks and wildlife service
australia zoo

Physical Features
• Looks somewhat like a porcupine and a hedgehog
• They have a round-shaped body covered with prickly spikes. Ouch!!
• They have short legs and strong claws capable of digging through the australian ground
• They have coats of brown or black hair and their thick to keep warm
They have a short snout
Echidnas are 30 cm to 45 cm in length and weigh between 2 - 5 kg
Males have non-venomous spur on each of their hind legs and it is blunt
It is all around Australia because they just go wherever their is ants or termites
It's community is shared with dingos, emus, kangaroos, wallabies, ants, wombats, goannas, tasmanian devils and some eagles
Some animals in the ecosystems include the tasmanian devil, goannas and eagles are echidnas predators, so they have to be in the community
Ants are the echidnas prey so it has to be in the community
blunt spur

Short beaked echidnas are common and wide speared
Their population is mainly in Australia and also in Papua New Guinea
They are solitary animals meaning that they live alone until they are old enough for mating
Since echidnas are solitary animals, they have no confirmed name for a group of echidnas
population of short-beaked echidnas
Biotic Factor
It doesn't have many predators, since it is inedible (not tasty) with those spines, yet the tasmanian devil eats it with the spines, goannas will steal the egg from the burrow and will eat eggs. Without predators , the echidna population will increase, and their will be not enough ants for them to eat and they will die.

Echidnas prey are ants and termites, so ants a biotic factor.

Grass, shrubs and plants are also biotic factors because without the plants, their will be nothing for the ants to eat and therefore will die. Then the ants have nothing to eat and will starve to death.

Echdinas ecosystem are dry grassland and sometimes savannas. Their biome is grasslands, biomes are larger than ecosystems.
Their ecosystem is very flammable and wildfires occur killing echidnas and other species
When predators eat the echidna like the tasmanian devils it's an interaction
Another would be echidna's prey (ants) when eaten by echidnas
Also the soil and the echidna, since it digs it's burrow to hide it's eggs and for grass to grow which ants eat and then echidnas eat

Abiotic factors
Every single living animal needs water to survive, so even echidnas needs to drink water occasionally whether it's from the due of grass or from lakes. So water is an abiotic factor.

Every living thing needs oxygen to survive including echidnas . So oxygen is an abiotic factor
It needs soil because echidnas dig in it, but also the soil gives nutrients to grass which may attract ants which the echidnas eat. Also, echidnas make burrows under the soil to keep their eggs in. Therefore, soil is an abiotic factor.
Special structures and behaviors for adaptation for survival
In danger they will roll up into a ball with their spines sticking out, so the predator will get hurt(behavior)
They have pouches like kangaroos,but the echidnas is hidden under it's spines, which female put their eggs or the small puggie(name for a baby echidna)(structure)
in danger, they will dig rapidly into the ground so their spines are showing(behavior)
They have spines that are used for defense (adaptation)
they have a long, sticky tongue (adaptation)
They have an electrical sensor in their nose, which can detect electrical signals from insect bodies(adaptation)
Any amazing facts

Echidnas are classified as mammals,yet they lay eggs
The name came from "Ekhidna" and english written/said echidna which was a half woman half serpent called the "mother of all monsters"
Echidnas have no teeth,instead they use hard pads to grind the ants up
In the northern part of Australia or when warmer , they tend to be nocturnal(active at night), but in the southern part of Australia or where cooler, they tend to be day-active
Echidnas can detect electrical signals from insect bodies
Echidnas are well swimmers showing a few spines and their nose when swimming
In the Sydney Olympic games, Millie the echidna was an character that was an echidna and it was one of the three mascots,the others were Syd the Platypus and Olly the kookaburra
dry grasslands
shrubs and sometimes plants
tasmanian devil
This is the end of my presentation.I hope you enjoyed my presentation and have a good day!
