Crustacea
By: Phil and Spencer
Phylogenetic Tree of Crustacea
Classification
• The class crustacea fits into the phylum Anthropoda and
the kingdom Animalia
• To be a apart of the class Crustacea, you must have an
exoskeleton that is grouped into three parts, cephalon
(head), the thorax, and the pleon (abdomen)
• Crustaceans have to have two antennae
• Also have to have gills for breathing
• Crustacea like crayfish, lobsters and crabs excrete waste
similar to humans through their anus but the American
lobster has have two urinary bladders on each side of
their heads where they urinate from.

Life Cycle of the American Lobster
Pistol Shrimp Food Getting and
Locomotion
• Pistol Shrimps have claws they use to
grab and tear their prey apart
• They have a powerful tail at the end of
their body that can propel them through
the water
Qualities of Crustacea
• Crustaceans have an open circulatory
system that transports substances through
their bodies by a heart that pumps blood
into body cavities, where tissues are
surrounded by the blood
• They exchange gases with gills that take
in oxygen and release carbon dioxide
• Many crustaceans feed on dead creatures
and digest them by using stomach acid,
much like humans
Interesting Fact #1
• A Japanese spider crab has a 12ft leg
span and can weigh up to 40 pounds
Interesting Fact #2
• The Stygotantulus stocki is the smallest
crustacea at 0.1mm in length
Interesting Fact #3
• Lobsters can produce noises. According to
the University of California, lobsters have
a mechanism of producing sound similar
to a violin. The lobster drags its antenna
across bumps next to its eyes to create
the noise.
