The Sea Mouse: this marine worm's body is fringed by photonic crystals that emit colorful displays of light
The scientific name of this species is Aphrodita aculeata, which is a reference to the Greek goddess of love and beauty, Aphrodite. It's also known as a sea mouse, thanks to its fluffy, almost mammalian appearance, but it's actually a type of marine worm.
Above: the photonic crystals have a color-shifting effect that makes them look almost like fiber-optic threads
The sea mouse is equipped with tufts of hollow, glassy bristles that produce a vibrant iridescence; these structures are known as photonic crystals, and Aphrodita aculeata is one of the few living organisms that is known to produce them.

This article explains how the colorful effect is produced:
Each sea mouse is covered in a dense felt of bristles that keep silty sediments away from the gills. But these "hairs" aren't hairs at all. The structures, known as chaetae, are actually modified scales, made largely of chitin, the same material that gives insects like jewel beetles their iridescence.
Each spine is essentially a hollow tube, and the wall of that tube contains 88 perfectly hexagonal chitin cylinders. Acting together, these cylinders form what is known as a "complete spectrum photonic crystal", the first-ever documented in a living organism. Photonic crystals are nanostructures that affect the motion of light travelling through them, and the sea mouse's crystalline spines are the most efficient in nature.

According to the same article:
As light hits the system of chitin tubes at different angles, it is spilt, scrambled and bounced back, producing the ever-changing rainbow you see. Light that comes in perpendicular to the spine reflects a deep red. Light coming in from off-axis angles, however, results in brilliant blues and greens.
Amazingly, the spines' ability to bend light surpasses even the most brilliant non-living photonic crystal we know of, the fire opal.

The purpose of this colorful display is still unclear. Many researchers believe that it is used to deter predators, while others argue that it might help to obscure the sea mouse's silhouette as it moves along the bottom of the sea, making it harder for predators to pinpoint the exact location of its body.

The genus Aphrodita contains several other species that are commonly known as sea mice, but Aphrodita aculeata is the only one that can produce this iridescence.

Aphrodita aculeata has an average length of about 7-15cm, and it can be found in certain parts of the North Atlantic, the North Sea, the Baltic, the Arctic, and the Mediterranean.

Dove-Shaped Perfume Vessels from Ancient Rome, c.50 CE: these glass vessels were filled with scented oils or cosmetic powders and then sealed, meaning that their contents could only be accessed by breaking the dove's neck or tail
These bottles were created and used as unguentaria (otherwise known as balsamaria) which are ancient vessels that were typically filled with scented oils, cosmetic powders, balms, or ointments. Unguentaria could be crafted from ceramic, glass, or stone, and they came in various shapes and sizes, but dove-shaped vessels made of glass were especially popular during the second half of the 1st century CE, when they were produced and distributed throughout the Roman Empire.

Each bottle was crafted from blown-glass that was carefully modeled into the shape of a bird; the inner cavity was then filled with perfume or cosmetic powder, and the tip of the tail was reheated and compressed, effectively sealing the vessel.
Above: dove-shaped vessels that were opened and emptied long ago, c.50-100 CE
As this article explains:
The vessels were produced with glass blowing pipes by so-called "free blowing," and are for this reason extremely thin-walled, with body thicknesses significantly below 0.1 cm.
After the containers had been filled, the tail feathers were sealed airtight by reheating to protect the contents from moisture. Parts of the containers, such as the head or tail feathers, had to be broken off in order to access the contents of the vessels, which means that they were disposable packaging.
Above: vessels with the tips of their tails broken off
Most of these bottles were made from clear or pale blue Roman glass, but some were crafted with a dark blue, green, purple, or yellow appearance instead:
As cheap, mass-produced goods, the packaging consisted mainly of the conventional thin-walled and transparent Roman glass with an unintentional light blue colouring. Specimens made of intentionally coloured transparent glass (e.g. dark blue, dark green, violet or yellow) are less common. This may also have to do with the fact that the pink or white contents could be visually better distinguished and marketed if the vessels were made of the conventional Roman glass, which offered more transparency to the beholder than the intentionally coloured glass.

Research suggests that many of these bottles were filled with powder, including pink substances that have been described as "blush" or "rouge," while others were filled with liquid.

Vessels with this design (which is also known as Isings form 11) have been unearthed at Roman-era sites located throughout Europe:
Evidence shows that these glass containers were widely marketed in the Roman Empire. The main areas of distribution are the central and northern Italian regions of Campania et Latium, Venetia et Histria, and Transpadana, along with the northwestern provinces of Gallia Belgica, Gallia Lugdunensis, Germania inferior and Germania superior [in what is now Italy, France, Belgium, Luxembourg, Germany, Austria, Switzerland and the Netherlands].
There is also evidence from the Balkan and Danube region in the provinces of Dalmatia and Pannonia, and also from the eastern Mediterranean in the provinces of Achaea, Creta et Cyrenae and Macedonia. The distribution in the western Mediterranean seems to be limited to Hispania Tarraconensis.
