The osprey (Pandion haliaetus), also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor, reaching more than 60 cm (24 in) in length and 180 cm (71 in) across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts.

The genus name Pandion derives from Pandíōn Πανδίων, the mythical Greek king of Athens and grandfather of Theseus, Pandion II. The species name haliaetus comes from Greek ἁλιάετος haliáetos "sea-eagle".

The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant.

As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and unique behaviour in hunting its prey. Its unique characteristics classify it in its own taxonomic genus, Pandion, and family, Pandionidae.

The osprey has several adaptations that suit its piscivorous lifestyle:

• reversible outer toes
• sharp spicules on the underside of the toes
• closable nostrils to keep out water during dives
• backward-facing scales on the talons which act as barbs to help hold its catch
• dense plumage which is oily and prevents its feathers from getting waterlogged.

The peacock "tail", is known as a train, consisting not of tail quill feathers, but highly elongated upper tail coverts. These feathers are marked with eyespots, best seen when a peacock fans his tail. The peacock tail produces colours by thin-film interference.

These tail feathers, or coverts, spread out in a distinctive train that is more than 60 percent of the bird’s total body length and boast colorful eye markings of blue, gold, red, and other hues.

The large train is used in mating rituals and courtship displays. It can be arched into a magnificent fan that reaches across the bird's back and touches the ground on either side.

When you think of top ocean predators, you probably think of sharks. That’s wrong!

Originally orcas, which are the largest members of the dolphin family, where called killer of whales. Then the name transformed into killer whales, leading to people to believe that they belong to the whale family... Well they actually eat whales and sharks as well!

The armadillo girdled lizard (Ouroborus cataphractus), also commonly known as the armadillo lizard, the armadillo spiny-tailed lizard, and the golden-armadillo lizard, is a species of lizard in the family Cordylidae.

The species is endemic to desert areas along the western coast of South Africa. It can be a light brown to dark brown in coloration. The underbelly is yellow with a blackish pattern, especially under the chin. Its size can range from 7.5 to 9 cm (3.0 to 3.5 in) in snout-vent length (SVL). It may grow to a maximum size of 20 cm (8 in) SVL.

A blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet composed of ionized matter traveling at nearly the speed of light) directed towards an observer.

Blazars are powerful sources of emission across the electromagnetic spectrum and are observed to be sources of high-energy gamma ray photons.

Blazars are highly variable sources, often undergoing rapid and dramatic fluctuations in brightness on short timescales (hours to days).

In 2009, a team of astronomers using the Swift spacecraft used the luminosity of S5 0014+81 to measure the mass of its super-massive black hole. They found it to be about 10,000 times more massive than the black hole at the center of our galaxy, or equivalent to 40 billion solar masses

I would probably break my ankles if I tried that!

Arkys lancearius, the triangular spider, is an Australian spider belonging to the family Arkyidae. It is an ambush hunter, commonly found resting on leaves and ferns or hanging from just a few threads of silk.

The front two pairs of legs are large, suited for grabbing small insects, while the rear pairs of legs are much smaller.

The body length of males is about 5.5 millimetres (0.22 in), while that of females are around 8 millimetres (0.31 in).

Body colour varies from yellow or orange to red with pale jewel-like markings on the heart shaped abdomen.

Egg sacs are produced in January or February and are a deep pinkish cream colour. They are usually around 8 mm in diameter and are covered in lighter coloured threads. Each sac contains about 70 eggs, each 0.7 mm in diameter

Ryugu is a near-Earth object and a potentially hazardous asteroid of the Apollo group. It measures approximately 900 metres (3,000 ft) in diameter and is a dark object of the rare spectral type Cb, with qualities of both a C-type asteroid and a B-type asteroid.

In June 2018, the Japanese spacecraft Hayabusa2 arrived at the asteroid. After making measurements and taking samples, Hayabusa2 left Ryugu for Earth in November 2019 and returned the sample capsule to Earth on 5 December 2020.

The samples showed the presence of organic compounds, such as uracil (one of the four components in RNA) and vitamin B3.
