Highest levels of coral cover in the Great Barrier Reef in 36 years but the ecosystem remains vulnerable

Scientists at the Australian Institute of Marine Sciences (AIMS) have stated that the coral cover in Australia’s Great Barrier Reef is the highest ever recorded, since records began 36 years ago, but the ecosystem remains vulnerable. 

The Great Barrier Reef on the eastern coast of Australia is the world’s largest natural reef system of over 2,900 individual reefs and 900 islands over 2,300 kilometres (1,400 miles) long. It was listed as a UNESCO World Heritage Site in 1981 and labelled one of the seven natural wonders of the world in 1997. 

AIMS scientists have been monitoring the levels of coral coverage in the reef to determine its health. They publish their findings annually.

Which land mammal is the only one that does not have paw pads?

Of all the land mammals that have paws, which land mammal is the only one that does not have paw pads?

Mammals are vertebrate (backboned) animals with fur or hair, a neocortex (a region of the brain) and the females have mammary glands to feed milk to their young. Mammals include humans, cats, dogs, horses, bears, rats, mice, rabbits, hares, weasels, elephants, etc. 

A paw is an animal’s foot with claws and paw pads. 

Not every mammal has paws. Ungulate (hoofed) mammals do not have paws – they have hoofs (or hooves).

Paw pads are hairless, usually dark-coloured or pink-coloured cushions on the soles of the feet of some land mammals. Paw pads help animals to grip the ground, making it easier to walk and run over its land terrain.

Not every mammal with paws has paw pads.

Where is the wishbone in animals?

Where is the wishbone in animals?

The scientific name for a wishbone is the furcula, which is Latin for ‘little fork.’

The furcula is a forked bone with two slightly curved parts that meet at the top, forming a type of V-shape.  There is a tradition that if two people each pull one side of the bone, it will snap, and the person who gets the larger part can make a wish.

How long do bird eggs take to hatch?

How long do bird eggs take to hatch?

Different bird species lay different sized eggs. Large birds lay larger eggs than smaller birds.

The chicks of larger bird species usually take longer to hatch than the chicks of smaller bird species.

Some examples include the following:

The Ostrich is the the largest bird in the world and its egg is the largest bird egg in the world. It measures about 15 centimetres (6 inches) long. The egg takes about 35-45 days to hatch.

What animals can be found in a rock pool?

What animals can be found in a rock pool?

A rock pool is a small body of tidal sea water among or near the coastal rocks on the shore. A rock pool is not a permanent body of water. Instead, it depends on the tide coming in and out.  Rock pools are visible at low tide.

Marine animals are found in a rock pool – in the water, in between the rock crevices, on the rocks, and under the rocks.

What is the difference between freshwater Flowing Water and Standing Water?

What is the difference between freshwater Flowing Water and Standing Water?

Flowing water occurs on land in freshwater streams and rivers. Flowing water usually begins to flow due to snowmelt or lakes that overflow. The water usually flows to the sea.

Flowing water can be fast-moving, slow-moving, or stagnant (not moving – it is motionless). Scientists usally regard motionless water to be stagnant if it has not moved in four consecutive days.

Do animals have emotions?

Do animals have emotions?

Humans have many emotions, such as happiness, sadness, anger, love, grief, pain, and so on.

Many animals have emotions too, particularly mammals, such as cats, dogs, horses, rodents, dolphins, apes etc. 

Although animals cannot talk, they express their emotions in other ways, such as making noises and acting in specific ways –  a dog wagging a tail, rubbing against a person, and even touching a human with its paws.

Sichuan Takin – a lot of bovine manure

The Sichuan Takin (Budorcas taxicolor tibetana) is an ungulate bovine mammal native to Sichuan, Gansu and Xinjiang in China and the Himalaya Mountains. It is a goat-antelope related to goats and sheep. 

The Sichuan Takin is known to produce a lot of manure. Most bovines (cattle – such as cows and bulls) produce a lot of manure.

How much manure does the Sichuan Takin produce?

Animals and the Climate

Animal scientists, called zoologists, study animal habitats and populations as well as behaviour. They observe the implications of changing conditions. If climate conditions change, animals might face changes to their food, water, and other resources. For example, if plants and animals die during a drought, it will impact the lives of other animals that feed on them.

When the habitat changes, some animals migrate, some move, some adapt, some die, some thrive, and some change their behaviour. For example, animals may look for different food and prey that they would not usually eat if their usual prey moves out of the region or if the vegetation changes.

Which animals have more than one heart?

Which animals have more than one heart?

Humans have one heart. Most animals have one heart, but there are animals with no heart, such as the jellyfish, and there are animals with more than one heart.  

The heart transports, or circulates, oxygen in the blood around the body. This is called the circulatory system. The human heart has red blood cells called haemoglobin. The human heart has 4 chambers (two atria and two ventricles). The cockroach, for example, has one heart with 13 chambers. The earthworm has 5 pseudo-hearts (false hearts) that are really aortic arches that act similar to a heart.

How many ants does an Anteater eat?

How many ants does an Anteater eat?

The Giant Anteater (Myrmecophaga tridactyla) is a large mammal in the Myrmecophagidae family from Central America and South America. Its head is elongated, with a thick neck, and a long, and tubular snout (nose). At the end of the snout are small nostrils and a small mouth with no teeth. 

The Giant Anteater is insectivorous – it eats insects – especially termites and ants, as well as beetles and honeybees. It does not destroy the ant nest or termite mound completely – instead, it leaves some ants and termites so that they can rebuild the colony to ensure that there are more ants and termites in the future. It uses its claws to dig them up, and then it uses its long, sticky tongue to collect the insects. Its tongue has backward-curved papillae with sticky saliva.

Why doesn’t the Meerkat get stung when eating scorpions?

Why doesn’t the Meerkat get stung when eating scorpions?  

The Slender-Tailed Meerkat (Suricata suricatta) is a small mammal in the Herpestidae family of meerkats. The Meerkat is a small Mongoose. It lives in the deserts of southern Africa. 

The Meerkat digs for food, such as lizards, snakes, scorpions, spiders, eggs, small mammals, centipedes, and millipedes.

Scorpions live in the deserts of southern Africa too. They have a venomous tail. The Meerkat is immune to (not affected by) the venom of the scorpion. Also, Meerkat parents teach their young to hunt and eat scorpions.

How has a Yak adapted in high altitudes?

How has a Yak adapted in high altitudes?

A Yak is a hairy bovine, like domestic cattle and the Bison. The Wild Yak (Bos mutus) lives in mountainous regions of the Himalayas, Mongolia, and Russia. For example, the Himalayan mountains are 4,000-6,000 metres (13,000-19,000 feet) tall.

Its shaggy hair keeps it warm in the cold mountains. Its hair is thicker and longer than the hair of domestic cattle. However, it is also adapted to the high altitudes in other ways.
