Arthropod Coloring/Labeling Activity
The kingdom Animals include many phyla, one of which is Athropoda. Athropods are considered the
“segmented” animals with hard exoskeletons. Within the phylum Arthropoda, there are four main
classes: Crustacea (the crustaceans), Myriapoda (millipedes and centipedes), Arachnida (the arachnids),
and Insecta (the insects).
First, label each animal below with which class it belongs to. Next, complete the coloring instructions
listed as well. Note, each animal may not have all of the items listed to color as they belong to different
classes within the phylum Arthropoda.
Color all the legs blue.
Color all the antenna brown.
Color all wings grey.
Color all the mandibles purple.
Color all claws or pinchers purple.
Color the head red.
Color the thorax yellow.
Color the cephalothorax orange.
Color the abdomen green.

and wall thicknesses. In this type of system, blood is pumped by a heart through vessels,
and does not normally fill body cavities.

permits movement of the body, maintains posture, and circulates blood throughout the
body.
5) Open Circulatory System - Blood is pumped by a heart into the body cavities, where tissues
are surrounded by the blood.
6) Reproductive System - The system of organs and parts which function in reproduction
consisting in the male especially of the testes, penis, seminal vesicles, prostate, and urethra
and in the female especially of the ovaries, fallopian tubes, uterus, vagina, and vulva.
7) Nervous Tissue – Main component of the nervous system.
8) Peripheral Nervous System – The nervous system outside the brain and spinal cord.
9) Connective Tissue - Tissue that connects, supports, binds, or separates other tissues or
organs, typically having relatively few cells embedded in an amorphous matrix, often with
collagen or other fibers, and including cartilaginous, fatty, and elastic tissues.
10) Lymph - A colorless fluid containing white blood cells, that bathes the tissues and drains
through the lymphatic system into the bloodstream.

Embryology Vocabulary Words - Part I
1. Reproduction – The production of offspring by sexual or asexual processes.
2. Sexual Reproduction - The production of a new living thing by two parent organisms, with
each parent contributing half the material in the DNA of the offspring.
3. Asexual Reproduction - A type of reproduction by which offspring arise from a single
organism, and inherit the genes of that parent only; it does not involve the fusion of
gametes and almost never changes the number of chromosomes.
4. Gestation Period - Fetal development period from the time of conception until birth.
5. Reproductive System - The organs and glands in the body that aid in the production of new
individuals.
6. Haploid - (of a cell or nucleus) having a single set of unpaired chromosomes.
7. Diploid - (of a cell or nucleus) containing two complete sets of chromosomes, one from
each parent.
8. Fertilization - The action or process of fertilizing an egg, female animal, or plant, involving
the fusion of male and female gametes to form a zygote.
9. Internal Fertilization - In mammals, reptiles, birds, and some types of fish the gametes meet
inside of the female's body.
10. External Fertilization - A strategy of fertilization in which a sperm cell unites with an egg cell
in the open, rather than inside a specialized organ within the body of a parent.
