Biology is...

Drawing from 2018

To start talking about microbiology, we need to start to clarify some fields. In this case, Biology is the scientific study of life, from the biggest, to the smallest💜
This field is really broad. Some areas are focused in certain organisms or part of them. You can check some recognized areas of Biology in this link.

I did this watercolor illustration about the main concept of biology, with some example organisms. Do you recognized some?
🌳✨🌌

Species in the illustration:
Largest organism (by area): Honey fungus (Armillaria ostoyae) 🍄
This may be the largest living fungus, and are the example of teamwork. Despite their individual size is only 5cm stipe, they can extend and connect their mycelia (like the roots for fungi) and extend as a single organism in a colony. The biggest reported was a colony spanning 8.9 km2 and may be as much as 605 tons found in the Malheur National Forest in the Blue Mountains of eastern Oregon, U.S.

Largest tree (by volume): Giant sequoia (Sequoiadendron giganteum) 🌲
The largest tree is the well known giant sequoia. This tree is native from Sierra Nevada and California, which grows up to 85 m of height and 7 m of diameter.

Largest animal: Blue whale (Balaenoptera musculus) 🐋
The maximum weight reported to the blue whale is 190 tonnes, which as 27.6 metres length. However, there’re other reported largest individuals (up to 33.6 m!), with estimated weight of 250 tonnes.

Largest invertebrate: Colossal squid (Mesonychoteuthis hamiltoni) 🐙
The largest colossal squid was captured in New Zealand, which had a size of ~14 m long and 750 kg  weight.

Small organism:
Bacteria: Vibrio parahaemolyticus 🔵
Bacteria are common (micro)organisms in our environment, and V. parahaemolyticus is not an exception. This species is naturally found in the marine environment and warm seawater.
Certain strains can be also pathogens, when ingested, causes gastrointestinal illness in humans. Do avoid its infection, we must eg. cook seafood when is consumed.

Archaea: Pyrococcus furiosus 🔴
This Archea species is found in thermal marine sediments and can live under extremely high temperatures (up to 100 °C!), therefore is a hyperthermophile. Also, it’s one of the few organisms who contain tungsten in one enzymes (aldehyde ferredoxin oxidoreductases), which is a rarely found element in biological molecules.

Fungi: Penicillium roqueforti 🥦
This fungus is commonly found in nature, it can be isolated from soil, decaying organic matter, and plants. Also, this is used for the production of blue cheeses, flavouring agents, antifungals, polysaccharides, proteases, and other enzymes.

Viruses: bacteriophages (viruses infect bacteria)
Viruses are the most abundant biological entity on Earth. They are as abundant that, if you fill a wine bottle with seawater, you wil have as many viruses as humans are in the whole planet… but don’t worry, the vast mayority are bacteriophages and they infect only bacteria (not humans).
