1) What mammal order is considered the most ancient and why?

Monotrematais the most ancient living order of mammals.

In addition to being egg layers (oviparous), members of this order share primitive skeletal features such as the shoulder girdle and skull characteristics that have been lost in other living mammals.
The name Monotremata means “one-holed,” in reference to the fact that both sexes have only one opening at the rear of the body, which is used for both reproduction and excretion

2)What animal is considered the most intelligent invertebrate and give an example proving this I.T.O behaviour.

Octopuses are highly intelligent, probably more intelligent than any other order of invertebrates. Maze and problem-solving experiments have shown that they do have both short- and long-term memory. Their short life spans probably limit the amount they can ultimately learn. They learn almost no behaviors from their parents, with whom young octopuses have very little contact

3)If you were to come across a sea cucumber, how might it react to your intrusion and what is this called?

When threatened, cucumbers can contract their muscles and shoot out water from their body making them shorter, thicker, and harder. Some can even shoot out their insides and then go and grow new insides.
Don't know what this is called though :?

SC!! :clap: :clap: :thumbs_up: :thumbs_up:

1) monotremata are indeed the most ancient mammal order as they do not give birth to live young but still lay eggs. Another characteristic of mammals is that they all possess mammary glands along mammary lines but the monotremata are different because they have no nipples rather the milk which is actually modified sweat seeps through the mothers abdomen and the young get milk from licking the mother.

2) Very right, octopuses as well as squid are very intelligent animals, another way in which they show their intelligence is that they are able to undergo colour changes within milliseconds, controlling the colour changes so specifically that every part of their body can be a different colour, this requires a large amount of nervous co-ordination. They use this in their behaviour, for example when a female is ready to reproduce and two males are interested in her, she is able to display bright mating colurs on one side of her body to the male she has chosen while on the other side of her body the colour becomes dull showing her disinterest.

3) sea cucumbers as a form of defense are able to expel a particular organ of their bodies through the anus to deter predators. most sea cucumber have this and it is called the organ of curvier and consists of many tough fibrous strands of collagen that are covered in mucous and can often also be laced with poison.

Your IT! SC, btw i like the new avvie :thumbs_up: :lol:

Hi all, next questions :)

1. Only one species of this bird exists and has been placed in a family separate from other birds. Which bird is it and why does it differ from other birds?

2. What does its diet consist of?

3. How would you describe the nest and how long does it take for the eggs to hatch?

(a) The Kakapo (Māori: kākāpō, meaning night parrot), Strigops habroptila[2], also called owl parrot, is a species of nocturnal parrot endemic to New Zealand

(b) The beak of the Kakapo is specially adapted for grinding food finely. For this reason, Kakapo have very small gizzards compared to other birds of their size. They are generally herbivorous, eating native plants, seeds, fruits, pollens and even the sapwood of trees. A study in 1984 identified 25 plant species as Kakapo food.[3] They are particularly fond of the fruit of the rimu tree, and will feed on it exclusively during seasons when it is abundant. Kakapo have a distinctive habit of grabbing a leaf or frond with a foot and stripping the nutritious parts of the plant out with their beaks, leaving a ball of indigestible fiber. These little clumps of plant fibers are a distinctive sign of the presence of Kakapo.[31][32] Kakapos are believed to employ bacteria in the foregut to ferment and help digest plant matter.[33]

Kakapo diet changes seasonally. The plants eaten most frequently during the year include some species of Lycopodium ramulosum, Lycopodium fastigium, Schizaea fistulosa, Blechnum minus, Blechnum procerum, Cyathodes juniperina, Dracophyllum longifolium, Olearia colensoi and Thelymitra venosa. Individual plants of the same species are often treated differently. Kakapo leave conspicuous evidence of their feeding activities, from 10×10 m to 50×100 m feeding ground areas.[3] Manuka and yellow silver pine scrubs are obvious signs of their center of feeding activities.

(c) Each court consists of one or more saucer-shaped depressions or "bowls" dug in the ground by the male, up to 10 centimetres (4 in) deep and long enough to fit the half-metre length of the bird. Kakapo are one of only a handful of birds in the world which actually construct their leks.[35] Bowls are often created next to rock faces, banks, or tree trunks to help reflect sound -[34] the bowls themselves function as amplifiers to enhance the projection of the males booming mating calls.[35] Each male’s bowls are connected by a network of trails or tracks which may extend 50 metres (160 ft) along a ridge or 20 metres (60 ft) in diameter around a hilltop.[34] Males meticulously clear their bowls and tracks of debris. One way researchers check whether bowls are visited at night is to place a few twigs in the bowl; if the male visits overnight, he will pick them up in his beak and toss them away.

Female Kakapo lay up to three eggs per breeding cycle.[38] They nest on the ground under the cover of plants or in cavities such as hollow tree trunks. They incubate the eggs faithfully, but are forced to leave them every night in search of food. Predators are known to eat the eggs and the embryos inside can also freeze to death in the mother's absence. Kakapo eggs usually hatch within 30 days,[39] bearing fluffy gray chicks that are quite helpless. After the eggs hatch, the female feeds the chicks for three months, and the chicks continue to remain with the female for some months after fledging.[38] The young chicks are just as vulnerable to predators as the eggs, and young have been killed by many of the same predators that attack adults. Chicks leave the nest at approximately 10 to 12 weeks of age. As they gain greater independence, their mothers may feed the chicks sporadically for up to 6 months.

Elzet, not the bird in question but very informative material! :)

You are right about the nest, though ; it is also scraped in the ground, but more a "hole" than a depression and the bird is much bigger.

(a) The ostrich is the only species in its family, although the east African or Masai ostrich is sub-classified. The ostrich is found throughout Africa and parts of the middle east.

(b) The diet of the ostrich mainly consists of plant matter, though it also eats insects. They mainly feed on seeds, shrubs, grass, and other plant matter;[13] occasionally they also eat insects such as locusts. Lacking teeth, they swallow pebbles that help as gastroliths to grind the swallowed food in the gizzard. An adult ostrich typically carries about 1 kg of stones in its stomach. Ostriches can go without water for several days, living off the moisture in the ingested plants.[25] However, they enjoy water and frequently take baths where it is available.[17] Ostriches are known to eat almost anything (dietary indiscretion), particularly in captivity where opportunity is increased.

(c) The females will lay their fertilized eggs in a single communal nest, a simple pit, 30 to 60 centimetres (12–24 in) deep and 3 metres (9.8 ft) wide,[26] scraped in the ground by the male. The first female to lay her eggs will be the dominant female, and when time comes to incubate, she will discard extra eggs of the weaker females, leaving behind about 20.[13] Ostrich eggs are the largest of all eggs (and by extension, the yolk is the largest single cell[citation needed]), though they are actually the smallest eggs relative to the size of the bird[27]. The nest may contain 15 to 60 eggs, which are, on average, 15 centimetres (5.9 in) long, 13 centimetres (5.1 in) wide, and weigh 1.4 kilograms (3.1 lb). They are glossy and cream in color, with thick shells marked by small pits.[18] The eggs are incubated by the females by day and by the male by night.[28] This uses the coloration of the two sexes to escape detection of the nest, as the drab female blends in with the sand, while the black male is nearly undetectable in the night.[18] The incubation period is 35 to 45 days. Typically, the male will defend the hatchlings, and teach them how and on what to feed. The survival rate is low for the eggs with an average of one per nest surviving. Predators are hyenas, jackals, and vultures.[13]

The life span of an ostrich is from 30 to 70 years, with 50 being typical.

Now you've got it! :thumbs_up: :clap:

1. Only one species of this bird exists and has been placed in a family separate from other birds. Which bird is it and why does it differ from other birds?

The ostrich is the only African member of the ratites. Ratites are a group of large flightless birds. Others include the emu in Australia and the rhea in South America.
Ostriches are in a separate order (Struthioniformes) to other birds and is the only member species. This is because they have unique characters, besides being big and heavy. They only have two toes, whereas all other birds possess at least three, usually four

2. What does its diet consist of?

Ostriches eat plants, insects like locusts, and small animals such as lizards. When an ostrich eats, food collects in their crop, which is at the top of the throat, until there is a big enough lump to slide down the neck. Lacking teeth, they swallow pebbles that help grind the swallowed foodstuff in the gizzard. Ostriches can go without water for a long time, however, they like water and enjoy bathing.

3. How would you describe the nest and how long does it take for the eggs to hatch?

The nest is a hole scraped in bare ground about 1 to 2 feet deep. The average egg is 6 inches in length, 5 inches in width, weighs about 3 pounds, and is shiny and whitish in color. Eggs take approximately 35 - 40 days to hatch.

:redface: Apologies, forgot that it was my turn...

(a) There are between 4 and 5 million species of animals or more in the world
(b) African elephants are capable of making a wide variety of vocal sounds, such as grunts, purrs, bellows, whistles, and the obvious trumpeting. Elephants are also capable of making low frequency sounds that are above the human range of hearing; this allows wandering individuals within the herd as well as several different herds to stay in direct contact over distances of many miles.
(c) Antarctic species of penguins can move quickly on ice by tobogganing on their bellies using their flippers and feet to help propel them along.
(d) Newborn green tree pythons are bright yellow, orange, or brick red and do not develop green coloring for 6 to 8 months.
(e) In Marabou Storks, the pouch on their throat is used for food storage.

Forgetting a couple of things, it seems.

Thanks O.

True or false it is.
