Beewolves are solitary wasps that dig holes in order to store bees that they have paralyzed. The female beewolf will lay a single egg on each bee, which will eventually be eaten alive by her larvae.
Pipe lining is the process of lining old dirty pipes with a liner that is soaked in a combination of resin and epoxy. Making the old pipes complete new without ripping them out.
An Archimedes’ screw is a machine used for transferring water from a low-lying body of water into irrigation ditches, Archimedes first described it around 234 BC.

The vibration in a PS5 controller is made by the rumble motors at the bottom of the handles (green object) spinning rapidly. Captured with CT scan.
Ratcheting mechanism inside bicycle rear hub allows coasting and locks when pedals are turned forward
The triboelectric effect is a type of contact electrification in which certain materials become electrically charged after coming into contact with another different material, and are then separated.
In order to evade predation, the female blanket octopus will unfurl her veil-like webbing to mimic the appearance and behavior of noxious sea creatures such as the venomous Portuguese man-o-war. Once the perceived threat (a diver in this case) is deemed innocuous, she relaxes her defensive posture.
3D animation that demonstrates the radius of destruction of the fallen line and gives advice on how to behave if you find yourself in this situation.
Many species of polychaetes (marine annelid worms) undergo epitoky whereby sexually immature worms transform into pelagic morphs capable of sexual reproduction. After fertilization, they release their gametes through rapid disintegration.
The eggs of the newts form algae underwater on their surface to produce oxygen, as the embryos require a continuous supply of oxygen to survive. Without the formation of algae, the embryos would not receive enough oxygen, which could lead to their death.
Flashlight fish or lantern-eye fish are represented by three fish species characterized by the presence of a luminescent organ just below the eye which the fish can turn on and off while it seeks prey and communicates within its group. The light is produced by bioluminescent bacteria.
Bioluminescence is typically used by animals to warn or evade predators, lure or detect prey, or communicate among members of the same species. This Dana octopus-squid, which has the largest known bioluminescent organs of any animal, is likely flashing its photophores to ward off the observer.
The kākāpō is one of the most endangered birds in the world with only 252 adult birds as of 2022 (only 49 in 1995). This is Sirocco in the Fiordland Wilderness of New Zealand’s South Island being given a health check by researchers. Every kākāpō is equipped with a tracking device for their safety.
The Archimedes’ screw is a simple machine used to transport water from a lower level to a higher level. It consists of a screw-shaped surface surrounded by a tube. As the screw is turned, water (red ball) is pushed up along the surface and out the top of the tube. This animation shows how it works.
Like all mammals, whales also shed their dead skin cells, either gradually while swimming around or even intentionally. These humpback whales were observed getting “spa treatment” in Gold Coast Bay by giving themselves full body exfoliation scrubs using the sandy seafloor.
