Description
Hydra are named after the nine-headed sea
snake of Greek mythology and are freshwater
relatives of corals, sea anemones and jellyfish.
All are members of a primitive phylum, the
Cnidaria, and share in common stinging
tentacles and a radially symmetrical body plan.
The gut of cnidarians has only one opening and
is termed the gastrovascular cavity. Unlike more
complex animals, cnidarians are designed
around 2 sheets of tissue: the ectoderm, lining
the exterior; and the endoderm, lining the
gastrovascular cavity. The two are separated by
a gelatinous partition named the mesoglea. This
layer is greatly expanded in jellyfish, but is
much reduced in hydra.
Hydra live attached to vegetation by the base of the tubular body or column, with their tentacles
suspended free in the water. At the base of the tentacles is the mouth. Smaller animals which
blunder into the tentacles are stung and paralyzed and drawn into the mouth. Most species of
hydra are less than 0.6 inches (15 mm) in length, not including the tentacles, and are
inconspicuous. Both column and tentacles are highly contractile and, by expelling gastrovascular
fluid from the mouth, a hydra can shrink to a fraction of its previous volume. Hydra will only
rarely be spotted in their natural habitats, but if samples of aquatic vegetation are transferred to a
clear glass or plastic container, they will often be found in considerable numbers. Both the
column and tentacles gradually extend in still water.
Several species of hydra have been recorded in the Great Plains, but most are difficult to identify
without detailed microscopy. Two species, however, are distinctive. Hydra (Chlorohydra

Anguillula aceti
Turbatrix aceti (Vinegar eels, Vinegar nematode) are free-living nematodes that feed on the
microbial culture, called mother of vinegar - that is used to create vinegar - and may continue to
persist in unfiltered vinegar.
Although they are harmless and non-parasitic, leaving eels in vinegar is considered objectionable
and is not permitted in vinegar bottled for consumers in the United States.[1] Manufacturers
normally filter and pasteurize their product prior to bottling to prevent the eels from occurring.
Vinegar eels are often given to fry (baby fish) as a live food, like microworms. Vinegar eels are
only found in unpasteurized vinegar. Vinegar that has been pasteurized no longer has the live
bacterial and yeast culture that these nematodes require for subsistence.[2]

Amoeba proteus
Amoeba proteus, previously Chaos diffluens, is an amoeba closely related to the giant amoebae.
This small protozoan uses tentacular protuberances called pseudopodia to move and
phagocytosize smaller unicellular organisms, which are enveloped inside the cell's cytoplasm in
a food vacuole,[1] where they are slowly broken down by enzymes. Amoeba proteus is very wellknown for its extending pseudopodia.
A. proteus possesses a nucleus containing granular chromatin, and is therefore a eukaryote.
Amoeba proteus
Return to main Sarcodina page
The Amoeba proteus is a large protozoan and
belongs to the Phyllum Sarcodina.
It has an ever changing shape and is
approximately 500-1000 um long. It can
almost be seen with the naked eye.
The Amoeba proteus can be ordered from
science supply companies and is the classic
specimen used in the classroom to
demonstrate the pseudopods in action. Other
species of amoebas are either too small, too
fragile or atypical in structure.
Amoeba proteus can sense light and tends to
move away from it. Just before it reproduces,
it rounds up into a ball with tiny pseudopodia
extensions. Over the next 15 minutes or so, it
splits and becomes two. Image below shows
one amoeba in the final stages of splitting.
Look carefully and you can see the clear
channel between the two new amoebas.

http://en.wikipedia.org/wiki/Paramecium
Paramecia, also known as Lady Slippers, due to their appearance, are a group of unicellular
ciliate protozoa, which are commonly studied as a representative of the ciliate group, and range
from about 50 to 350 μm in length. Simple cilia cover the body, which allow the cell to move
with a synchronous motion (like a caterpillar). There is also a deep oral groove containing
inconspicuous compound oral cilia (as found in other peniculids) used to draw food inside. They
generally feed on bacteria and other small cells. Osmoregulation is carried out by a pair of
contractile vacuoles, which actively expel water from the cell absorbed by osmosis from their
surroundings.
Paramecia are widespread in freshwater environments, and are especially common in scums.
Certain single-celled eukaryotes, such as Paramecium, are examples for exceptions to the
universality of the genetic code (translation systems where a few codons differ from the standard
ones).

The rotifers make up a phylum of microscopic and near-microscopic pseudocoelomate animals.
They were first described by Rev. John Harris in 1696, and other forms were described by Anton
van Leeuwenhoek in 1703.[1] Most rotifers are around 0.1–0.5 mm long (although their size can
range from 50μm to over 2 millimeters),[2] and are common in freshwater environments
throughout the world with a few saltwater species. Some rotifers are free swimming and truly
planktonic, others move by inchworming along the substrate, and some are sessile, living inside
tubes or gelatinous holdfasts that are attached to a substrate. About 25 species are colonial (e.g.,
Sinantherina semibullata), either sessile or planktonic. Rotifers play an important part of the
freshwater zooplankton, being a major foodsource and with many species also contributing to the
decomposition of soil organic matter.[3]
