Dakota is the only one of my animal roommates who would most likely never snap or bite. But because he's a snake, people are afraid. A 2008 study showed that the sight of a snake silhouette triggers stress in babies as young as 8 to 14 months old. So it's not something learned, but innate. Other studies have confirmed similar reactions in non-human primates. But the stress reaction does not automatically lead to a fear of snakes. As early as the 1980s, it was recognized that rhesus monkeys only react fearfully to snakes after they have observed it in other monkeys. It was an advantage for our ancestors to be able to recognize a snake quickly and react immediately. For one thing, venomous snakes pose a danger, and for another, our ancestors were also natural prey for giant snakes. But Dakota is just a harmless corn snake that strangles its prey.😇

Seeing in the Dark and the Green: How Eyes and Leaves Share a Lighty Secret

The world of biology reveals surprising connections, and the human eye and a seemingly ordinary leaf share a fascinating one. Both organs rely on sophisticated light-sensing mechanisms to function effectively in their environments, despite their vastly different purposes.

Within the human eye, the retina houses two crucial photoreceptor cell types: rods and cones. Rods, responsible for low-light vision, utilize rhodopsin, a specialized protein, to capture even the faintest light signals. Cones, responsible for color vision, rely on various forms of iodopsin to differentiate colors in bright light conditions. Both rhodopsin and iodopsin function by undergoing a shape change upon encountering light, triggering a biochemical cascade that ultimately translates light energy into electrical signals the brain interprets as vision.

Plants exhibit a similar strategy. Nestled within their leaves lies phytochrome, a remarkable molecule that, like its counterparts in the eye, acts as a light receptor. Phytochrome exists in several states depending on the specific wavelengths of light it absorbs. By sensing variations in light intensity and spectrum, phytochrome provides the plant with vital information about its surrounding environment. This information plays a critical role in processes like photosynthesis, where plants utilize sunlight as an energy source, and regulates growth patterns based on light availability.

In both the eye and the plant, the photosensors function together with chromophores: retinal in the eye and phytochromobilin in the plant.

This unexpected parallel between the human eye and the leaf underscores a fundamental principle in biology – the ability to detect light is a powerful evolutionary advantage. By harnessing the power of light, both humans and plants gain the ability to navigate their environments, grow, and thrive.

When I discover something...😅

Tiny leopard slugs (Limax maximus) everywhere! 🥰 They are totally cute as babies and popular in gardens because they fatally attack other slugs.☠️

🐞🌿 A ladybug nymph fell on my hand and clung to it tightly. 😅🤷‍♂️ I let it climb into a bush. Baby saved! 🤗

Green shield bug,
Palomena prasina
(07/2021 in Oberursel)


Little stinker in its fourth instar. Two moults remain until adulthood. It's a very common European species. You can find them from North Africa across Europe to Central Asia. It prefers to live on deciduous trees (linden, alder), bushes, nettles and thistles. I found this one below a linden tree. In German we call them Grüne Stinkwanze (green stink bug). My friends from North America have a very similar bug with that name (Chinavia hilaris). But they differ much in color in their larval stage and have a few small differences as adults. Both species are member of the Pentatomidae family, generally called shield bugs or stink bugs. They have in common that they release a pungent defensive spray when threatened, disturbed or crrrrushhhhed.💚
