…this is so rad
Aristolochia arborea, which imitates a fungus (a whole bunch of them) and Ophrys insectifera which imitates female wasps (here’s a nicer image, here’s one of a wasp trying to copulate with it in which case it gets pollinated. haha the irony)
plants are basterds
All clownfish are born male. When they become adults, the largest, most dominant fish becomes a female, and the second largest becomes the breeding male. If the breeding female disappears, the breeding male (now the largest of the group) will become a female, and so on. In other species of tropical fish, when the ratio between males and females becomes imbalanced, dominant females may become males.
I love how much humans fuss over their genders or how they do NOT want to have genders and fish just randomly (well not exactly but you get my point) change their sex just like that. Man, being fishes would save us quite some money :-D
Obturator (an object used to obstruct a hole) has to be my most favourite word in botany EVER.
It just sounds so much like a silly supervillain
Totally studying

That’s even better than the big inflation back in ye olden times when people had to buy stuff with wheelbarrows full of money (DID they actually use wheelbarrows? It’s often been said but I’m not sure if this is just a hyperbole…)
CAM-Pflanzen (Crassulacean Acid Metabolism): Stomata nachts offen -> CO2-Fixierung und Speicherung als Äpfelsäure, am Tag Stomata geschlossen (Verdunstungsschutz), CO2 wird freigesetzt und der Photosynthese zugeführt.
Kelp: besonders groß wachsende mehrzellige Algen aus der Ordnung der Laminariales.
nicht zu verwechseln mit Kelpie :
Wirft man einem Kelpie einen Brautschleier über den Kopf, so muss er einem zu Diensten sein.

Botulinum is pretty damn poisonous
But I didn’t know HOW poisonous until now:
It is the most acutely toxic substance known, with a median lethal dose of about 1 ng/kg when introduced intravenously[3] and 3 ng/kg when inhaled.[28] This means that, depending on the method of introduction into the body, a mere 90–270 nanograms of botulinum toxin could be enough to kill an average 90 kg (200 lb) person, and four kilograms of the toxin, if evenly distributed, would be more than enough to kill the entire human population of the world.
this means that 0,000000065g could kill me. Fffffffff this is like…NOTHING.
The toxin itself is rapidly destroyed by heat, such as in thorough cooking.
hooray!
