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
