Study Notes
Animal Classification & Characteristics
- Domain, Kingdom, and Phylum: Sea stars - Eukarya, Animalia, Echinodermata; Planarians - Eukarya, Animalia, Platyhelminthes; Blue Crabs - Eukarya, Animalia, Arthropoda; Tapeworms - Eukarya, Animalia, Platyhelminthes
Animal Classes
- Squid: Cephalopoda
- Horseshoe crab: Polyphemus
- Slug: Gastropoda
- Grasshopper: Insecta
- Snail: Gastropoda
Flatworm Classes
- Three classes of flatworms: planarians, flukes, tapeworms
Planarian Sense Organs
- Sensory lobes on the side of the head used for finding food
- Eye spots to detect light
Tapeworm Adaptations
- No Eyes: Live in dark environments; no need for sight
- No Digestive System: Absorb nutrients from their host's digestive tract
Roundworm Complexities
- Eye Spots: More complex than cnidarians
- Sensory Lobes: More complex than cnidarians
Detritivores
- Animals that feed on dead plant and animal matter
Segmented Worm Classes
- Earthworms
Earthworm Circulatory System
- Closed circulatory system - blood confined to vessels throughout the body. This differs from clams (mollusks) which have an open circulatory system where blood flows freely.
Earthworm Digestive System
- Complex digestive system with a mouth and anus, specialized regions for different functions. This is more complex than a pinworm's simpler digestive system.
Earthworm Respiration
- Breathe through their skin
Polychaetes
- Segmented worms that live in water and have bristles
Earthworm Benefits for Plants
- Contribute to healthier, more productive soil environments, leading to stronger plant growth
Earthworm Locomotion
- Muscles and bristles
Mollusk Classes
- Gastropoda
- Bivalvia
- Cephalopoda
Mollusk Body Parts
- Shell: Protection
- Mantle: Covers visceral mass
- Visceral Mass: Contains gut, gills, other organs
Mollusk Differences
- Chart comparing shells, movement, feeding, and circulatory systems in gastropods, bivalves, and cephalopods.
Cephalopod Defense
- Camouflage, ink release, jet propulsion
Arthropod Classes
- Arachnids
- Millipedes/centipedes
- Insects
- Crustaceans
Arthropod Characteristics
- Segmented bodies, jointed limbs, exoskeleton, nervous system
Echinoderm Exoskeleton
- Endoskeleton made of calcium carbonate plates (ossicles)
Echinoderm Symmetry
- Radial symmetry with ossicles arranged around a central axis.
Echinoderm Defense
- Spines, pedicellariae (for defense and protection)
Echinoderm Nervous System
- Nerve ring, radial nerves, simple eyes, sense touch, chemical signals
Echinoderm Water Vascular System
- Sieve plate, ring canal, radial canals, tube feet, ampullae
Echinoderm Groups
- Sea stars or starfish
- Brittle stars and basket stars
- Sea urchins and sand dollars
- Sea lilies and feather stars
- Sea cucumbers
Endotherms vs. Ectotherms
- Endotherms (mammals) – internally regulate body temperature
- Ectotherms (reptiles) – body temperature regulated by the environment
Cartilaginous vs. Bony Fish
- Chart comparing skin, skeletons, breathing methods, buoyancy mechanisms in cartilaginous and bony fish.
Fish Circulatory System
- Closed circulatory system
Lateral Line System
- Sensory system in fish and some amphibians, detects movement, vibrations, pressure changes, currents to navigate, hunt, avoid predators and communicate.
