Over the life of your printer, you’ll probably pay more than 500% of the total price of the printer itself on ink refill cartridges. At $30, a 42ml cartridge of black printer ink comes out to 71 cents per ml. On the other hand, the Red Cross charges $200 for 500 ml of blood, which comes out to about 40 cents per ml.

These rocks live on the coast of Peru and Chile. Two siphons connect the organisms to the surrounding ocean, where one is used to exhale and the other to inhale. They feed on sea water by inhaling and filtering out all edible microalgae by use of a moving layer of mucus found in its enlarged pharynx. The other siphon is then used to exhale the water out. The Pharynx acts as the organism’s mouth and is connected to its digestive tract.

The Pyura chilensis contains clear blood and high quantities of vanadium, a rare and mysterious element. The vanadium is 10 million times more in the creature than in sea water. How they are able to accumulate high quantities of vanadium and what part it plays in the creature’s development is not yet known.

These rocks belong to the Ascidiacea non-moving class of sac-like invertebrate marine filter feeders, known in other words as sea squirts. Since they cannot move around in search of mates, the Pyura chilensis are hermaphroditic. They are born male but over time grow female organs. Breeding involves the unique and fascinating release of both sperms and eggs into a fertile cloud, where they meet to form off springs that are tiny and tadpole-like. These eventually settle on rocks nearby and grow into adult form.

The Pyura chilensis belongs to the Tunicata Subphylum class due to the thick “Tunics” made of Tunicin that cover it. These help them blend into the surroundings. The Tunicin is a hard matrix of molecules that assist the creatures attach themselves on to hard surfaces. An epidermis and muscular band lines the insides of the tunics. Seeing one of these creatures sliced in half is the most bizarre thing ever because inside these Tunics is a tissue like mass that is bright red and that will leave you flabbergasted.

The raw insides of this alien-like organism are a delicacy and are used as ingredients for stews or eaten in their raw form. Locals describe them as having a “bitter” and “soapy” taste that has a “weird iodine flavor”. For many years, the Chilean and Peruvian locals have been fishing the Pyura chilensis for commercial use.

Why is the poo so popular? Turns out panda excrement is loaded with various vitamins and minerals that come from bamboo – what pandas primarily eat.

“Pandas have a very poor digestive system and only absorb about 30 percent of everything they eat,” Yashi told the Australian website. “That means their excrement is rich in fibers and nutrients.”

According to Yashi, those important nutrients end up in the tea through that fertilization process.

These nutrients are no joke, and Yashi claims that they are immensely powerful.

“Just like green tea, bamboo contains an element that can prevent cancer and enhance green tea’s anti-cancer effects if it is used as fertilizer for the tea,” he told SBC.com.
