Study Notes
Kingdom Animalia
- Multicellular organisms that are heterotrophic.
- Reproduction primarily occurs through sexual means.
Phylum Porifera
- Includes sponges, aquatic animals with asymmetrical body structures.
- Composed of two cell layers, capable of asexual and sexual reproduction.
Phylum Echinodermata
- Characterized by a water vascular system and internal skeleton.
- Features spiny skin and symmetry; examples include starfish, sea urchins, and sea cucumbers.
Phylum Annelida
- Known as segmented worms, possessing a complete digestive tract.
- Features a closed circulatory system and a ventral nervous system.
Phylum Nematoda
- Comprises roundworms with long, cylindrical bodies.
- Equipped with a digestive system featuring a mouth and anus; most are parasitic.
Phylum Cnidaria
- Aquatic organisms with symmetrical, saclike bodies and two cell layers.
- Exhibits two body forms: medusa and polyp; includes jellyfish, corals, and anemones, reproducing sexually.
Phylum Arthropoda
- Characterized by segmented bodies and jointed appendages.
- Possesses an exoskeleton for support and protection.
Class Crustacea
- Distinctive for having two pairs of antennae; primarily aquatic.
- Respiration occurs via gills; examples include lobsters and crabs.
Class Arachnida
- Lacks antennae; comprises two body regions and four pairs of legs.
- Includes species such as spiders and scorpions.
Class Insecta
- Features include one pair of antennae, three body regions, and three pairs of legs.
- Many insects have two pairs of wings; examples are flies, ants, and beetles.
Phylum Mollusca
- Soft-bodied, unsegmented creatures with a muscular foot and mantle.
- Possesses a radula and well-developed digestive, circulatory, and nervous systems.
Class Bivalvia
- Notable for a two-part hinged shell and absence of a head or radula.
- Examples include clams, oysters, and mussels.
Class Gastropoda
- Characterized by a head with tentacles; most possess a spiraled shell.
- Includes snails and slugs among its members.
Class Cephalopoda
- Features a large head surrounded by arms or tentacles.
- Shell may be absent, internal, or external; highly developed nervous systems found in species like octopuses and squids.
Phylum Chordata
- Defined by the presence of a notochord, paired gill slits, and a dorsal nerve cord.
Subphylum Vertebrata
- Distinguished by an enlarged brain and vertebral column encasing the dorsal nerve cord.
Class Chondrichthyes
- Comprises fish with skeletons made of cartilage, equipped with movable jaws and fins.
- Sharks serve as a prominent example.
Class Osteichthyes
- Features a bony skeleton, movable jaws, overlapping scales, paired fins, and an air bladder.
- Includes species like salmon, trout, and carp.
Class Amphibia
- Moist, smooth skin lacking scales; possesses four limbs.
- Requires water for reproduction; examples include frogs and toads.
Class Reptilia
- Notable for dry, scale-covered skin and four limbs.
- Internal fertilization occurs, with organisms having lungs and a three-chambered heart; includes turtles and alligators.
Class Aves
- Birds with feathers; front limbs adapted as wings.
- Eggs are encased in hard shells, with a four-chambered heart and warm-blooded metabolism; includes robins and chickens.
Class Mammalia
- Mammals nourish their young with milk, characterized by fur or hair covering.
- Possesses a four-chambered heart and is warm-blooded; notable examples include humans, mice, and tigers.
