Animals—Living, Protists
Protists, Ciliates
Unicellular organisms characterized by movement using cilia or ciliary-derived
structures. This group is commonly studied in feeding behavior and simple response
experiments. Ciliates have two, or more, nuclei—a macronucleus (typical cell functions)
and at least one micronucleus (reproduction). Internal organelles are easily
visible using a compound microscope with a 40X objective. Possession of cilia is the
only common characteristic. Some are typically mobile while others prefer attachment
to a substrate. Feeding behaviors also vary. Vital stained cultures have a dye
added that stains the internal organelles for easier observation. Ciliates prefer calm
water, room temperature and dim light. They will move away from a microscope’s
field of view. Culture contains enough live food to last several days. Aerate daily
using included pipet.

LM1160 100 25.65
LM1076 Paramecium caudatum. Possesses one micronucleus and one macronucleus. Osmoregulatory
action of contractile vacuole can be observed by exposing organism to hypo- and hypertonic
solutions.

LM1077 100 25.65
LM1175 Paramecium caudatum—Vital Stained. Prestained living culture. Stain highlights internal
structures and organelles, making observations easy and saving time.

LM1078 Paramecium multimicronucleatum. The largest of the commonly studied paramecia
(200–350 μm). With one macronucleus and three or four micronuclei.
30 9.04
LM1079 100 25.65
LM1082 Stentor. Distinctive trumpet-shaped cells with vivid blue-green coloration due to the pigment
stentorin. With a large, beaded macronucleus it may be up to two millimeters in length.
30 8.65
LM1083 100 25.65
LM1084 Vorticella. Sessile, bell-shaped ciliate anchored to the substrate by a contractile stalk. The
stalk will coil up like a spring when the organism is disturbed. With an elongate, curved
acronucleus.

★MAINTENANCE: Protist cultures are shipped in clear, two- to eight-ounce
polystyrene jars. Immediately upon receipt, loosen caps and aerate cultures with clean
pipet (included). Protozoans should be kept in diffuse, indirect light at temperatures
from 18 °C to 22 °C.
Long-term cultures should be maintained in clean culture dishes containing medium to
a depth of one inch. Dishes should be stacked or loosely covered to limit evaporation
and contamination. Subculture protozoans (inoculate fresh medium) once a month.

Protists, Pseudopods
Unicellular organisms characterized by movement using pseudopods, which act in
both locomotion and feeding behaviors (phagocytosis). Internal organelles are easily
visible using a compound microscope with a 40X objective. These slow movers are
easy for students to follow and observe organelles and behavior. A. proteus contains
a single nucleus. C. carolinesis is multinucleate. A. proteus vital stained are living
proteus that have been stained for easier observation. Pseudopods prefer stagnant
water, room temperature, dim light or darkness and tend to move away from a microscope’s
field of view. Culture contains enough live food to last several days. Aerate
daily using included pipet.
Amoeba proteus
LM1062, etc.
Catalog No. Description Pkg. Size Price/Pkg.
LM1062 Amoeba proteus. Common in freshwater lakes, ponds and slow-moving streams. Popular for
the study of basic animal cell structure, major organelles and the process of phagocytosis.
Single nucleus.

LM1065 100 25.05
Protists, Flagellates
Unicellular organisms characterized by movement using one or more flagella.
Flagella act in locomotion. Below flagellates are all photosynthetic species with red
eyespots. Internal organelles are easily visible using a compound microscope with
a 40X objective. Flagellates prefer calm, room temperature water. Culture contains
enough live food to last several days. Aerate daily using included pipet.
Catalog No. Description Pkg. Size Price/Pkg.
LM1039 Euglena. Extremely active organism moves by means of single flagellum. Popular for
behavioral studies involving responses to light, temperature and pH (taxes). Also used for
vitamin B12 assay.
