Animal Flashcards
Vertebrates
an animal of a large group distinguished by the possession of a backbone or spinal column, including mammals, birds, reptiles, amphibians, and fishes.
Invertebrates
Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a backbone or spine), derived from the notochord.
Consumer
A consumer is a person or a group who intends to order, orders, or uses purchased goods, products, or services primarily for personal, social, family, household and similar needs, not directly related to entrepreneurial or business activities.
Ganglion
A ganglion is a group of neuron cell bodies in the peripheral nervous system. In the somatic nervous system this includes dorsal root ganglia and trigeminal ganglia among a few others.
Gut
The gut refers to your gastrointestinal (GI) system, the health of which is generally determined by the levels and types of bacteria in your digestive, intestinal tract.
coelom
the body cavity in metazoans, located between the intestinal canal and the body wall.
Bilateral Symmetry
the property of being divisible into symmetrical halves on either side of a unique plane.
Radial Symmetry.
symmetry around a central axis, as in a starfish or a tulip flower.
Asymmetry
lack of equality or equivalence between parts or aspects of something; lack of symmetry.
Sponges
Sponges, the members of the phylum Porifera, are a basal animal clade as a sister of the Diploblasts.
Cnidarians
an aquatic invertebrate animal of the phylum Cnidaria, which comprises the coelenterates.
flatworms
The flatworms, flat worms, Platyhelminthes, or platyhelminths are a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates.
Roundworms
The nematodes or roundworms constitute the phylum Nematoda, with plant-parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments.
Mollusks
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda. The members are known as molluscs or mollusks. Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species.
Open circulatory system
Open circulatory systems are systems where blood, rather than being sealed tight in arteries and veins, suffuses the body and may be directly open to the environment at places such as the digestive tract.
