The 6 Kingdoms sort
The blobfish (Psychrolutes marcidus) is a deep
sea (600-1,200 m) dwelling fish. To deal with
the intense pressure found at these levels, the
blobfish’s tissue is primarily a gelatinous mass
that contains no cell wall, which is slightly less
dense than water. This allows it to float slightly
above the sea floor without spending much
energy on swimming. It primarily swallows
eatable matter (like crab) that floats in front of
it.
The aye-aye (Daubentonia madagascariensis) is a
lemur native to Madagascar. The aye-aye finds food
like a woodpecker; it taps on the bark of trees,
gnaws on the tree, and then pulls the grubs out
with its fingers. Its cells have no cell wall, which
help provide flexibility in the aye-aye’s tissue.
The amoeba is a unicellular eukaryotic
organism that moves and eats using its
pseudopodia (“false feet”) to surround and
engulf other organisms living in its aquatic
environment.
The Hydnellum peckii is commonly called
Strawberries and Cream, Bleeding Tooth, or
Devil’s tooth because of its unique red and white
appearance. Its red gel has anticoagulant
properties. This heterotrophic organism reproduces
with spores and can be found as an individual or in
a colony. Its cell walls contain chitin.
The Azra microphylla is a muticellular autotroph
found in Chile. Its inflexible cell walls contain
cellulose. It produces an odor similar to white
chocolate.
The paramecium is a unicellular organism that
moves in an aquatic environment with cilia. It is a
eukaryote that feeds on micro-organisms like
bacteria and yeast.
Tremella foliacea is commonly called leafy
brain or jelly leaf. This multicellular organism is
a parasite to fungi. It is said to be edible, but it
is not much desired. Even though its cell walls
contain chitin, you won’t see it on your pizza
(unless you turn into a zombie). 
Euglena is a unicellular organism that can undergo
photosynthesis or surround and consume an
organism by phagocytosis. It does not have a cell
wall; instead this eukaryotic organism is
surrounded by a protein layer supported with
microtubules, which makes it very flexible and
motile.
E. coli is a prokaryotic organism typically found
in the lower intestine of various animals. Some
strains can cause food poisoning in humans. Its
cell walls contain peptoglycan.
Ferroplasma is a prokaryotic organism that obtains
its food through a chemical reaction involving iron
and oxygen. It produces sulfuric acid as a result,
which means that ferroplasma are acidophiles.
They are most often found in the runoff produced
from heavy mining that involves pyrite. Its cell walls
do not contain peptoglycan.
Halobacteria are prokaryotic extremophiles
found in water nearly saturated with salt like the
Dead Sea. The cell walls of halobacteria do not
contain peptoglycan. However, the pigment
found in them can turn the water they are found
in pink.
Streptococcus is a prokaryotic organism that
reproduces by dividing along many axes and
create grape like clusters of cells. Strains of this
organism are responsible for diseases like strep
throat, meningitis, and bacterial pneumonia. The
cell walls of this organism contain peptoglycan.
The leafy sea dragon (Phycodurus eques) is a
multicellular organism that camouflages itself
to appear like floating sea weed. The fins that
propel it are too small to be seen by the naked
eye. The leafy sea dragon feeds on small
creatures such as plankton off the coast of
Australia.
Salmonella Typhi is another type of salmonella;
this strain is responsible for typhoid fever. This
prokaryote releases toxins that affect the
stomach and intestinal area, resulting in
vomiting, diarrhea, high fever and bloody
stools. Typhoid fever is very dangerous, and can
be fatal for those who do not seek medical
treatment after symptoms begin to appear.
Diatoms are microscopic unicellular organisms that
are found in aquatic environments. They are
photosynthetic autotrophs. They create a shell
made of silica. When these eukaryotes die, their
shells are used as a key ingredient in toothpaste
because they help remove plaque buildup from
teeth.
Penicillum are eukaryotic heterotrophic organisms
that cause the “fuzzy” blue mold on breads. They
can also be used to make penicillin, which is an
antibiotic. Interestingly, penicillum reproduce
asexually by spore dispersal.
Yeast is a unicellular eukaryotic organism that is
used commercially to make bread, beer, and
cheese. Although some types of yeast can be
helpful, candidiasis is a skin infection caused by
yeast. The cell walls of yeast contain chitin and it
reproduces asexually through budding. Yeast’s
obtain their nutrition through absorbing nutrients
around them.
Bifidobacterium are prokaryotes that help
maintain homeostasis in a person. They are often
added to probiotic yogurts and found in breast
milk. These organisms are heterotrophs whose
cell walls contain peptidoglycan.
Methanococcales are prokaryotes that live in
extremely hot and oxygen deprived waters at
the base of a sea chimney in the deep ocean.
Methanogens are extremely important in
environments that are anaerobic (lacking
oxygen). They work by taking carbon dioxide
and hydrogen and converting it to methane gas
and water.
Streptococcus pyogenes is an organism that can
cause necrotizing faciitis. In other words, it is a
flesh-eating bacterium. This rare disease is
usually only contracted by people with
compromised immune systems. Sources
include: undercooked contaminated meat,
working at a waste water treatment plant,
hospital settings, and raw produce from farms
fertilized with human sewage.
Sulfolobus acidocaldarius is a prokaryotic organism
that grows in volcanic hot springs where they have
a high sulfur concentration and a low pH (very
acidic) environment. This organism is of interest to
researchers because of its ability to function at a
wide range of temperatures. It was first discovered
in the hot springs of Yellowstone National Park, and
later found in Italy and El Salvador.
Although the Sundew is a multicellular
photosynthetic organism, it compensates for the
poor soil nutrients by trapping and digesting
insects. This eukaryotic organism reproduces
sexually with the assistance of pollinators such as
bees.
Kelp is a type of marine algae that
photosynthesizes in the ocean. It has gas filled
pockets that help it stay close to the surface of
the ocean. This multicellular eukaryotic organism
is notable because it does not contain cellulose in
its cell walls or roots that anchor it to the ocean
floor. Kelp can grow up to 150 feet tall. A large
quantity of kelp is referred to as a “kelp forest”
by many people—especially those who harvest
kelp to sell as a food source.
According to the Guinness Book of World
Records, Deinococcus radiodurans is the toughest
bacterium on Earth. It can survive cold,
dehydration, vacuum, acid, and extreme levels of
radiation. Four cells normally stick together,
forming a tetrad. The bacteria are easily cultured
and do not appear to cause disease. Colonies are
pink to red in color.
