Study Notes

Importance of Invertebrate Zoology

Studying invertebrate zoology is not practical for recreational hunting or sport fishing
Invertebrates can be deadly to humans as parasites or vectors for serious human diseases

Characteristics of Invertebrates

The largest living invertebrate is the lion's mane jellyfish
Crabs have a leg span of up to 12 feet

Model Invertebrate Systems

Model invertebrate systems play a potential role in understanding human diseases

Disease Vectors

Mosquitoes are vectors for serious human diseases

Developmental Biology

Observations of clumping amoebocytes in injured starfish larvae led to the field of study in developmental biology

Taxonomy

Linnaeus's system for naming species is called binomial nomenclature
The first word in binomial nomenclature names the genus
The term for species having very large geographic ranges or worldwide distributions is cosmopolitan

Protozoa

Unicellular eukaryotes (protozoa) are found in aquatic environments
Protozoa play a crucial role in the economy of nature
50% of protozoa species are symbiotic in or on animals or plants
Protozoa can live successfully in extreme environments, such as hot springs and Antarctic lakes

Species Adaptations

The term for species adaptations that vary greatly as environmental conditions change is phenotypic plasticity
The term for species with very restricted geographic distributions is endemics
The term for the person who first describes a type specimen and publishes the name of a species is author
