Respiratory Structure of Crayfish
Gills- In cephalothorax
Gas exchange structure, extension of bodies (inside or outside)
Permeable to gases, vascularized (blood vessels)
Respiratory Structure of Brineshrimp
Paddle shaped leg segments
Gas exchange surface
Respiratory Structure of Horseshoe crab
Book Gills
Page like structures (lamellae) in constant motion so water can flow through them
Oxygen from water to blood in hemocoel
Respiratory Structure of Muscle shrimp and seed shrimp
Lack Gills
Bivalve carapace
Respiratory Structure of Centipede
Spiracles--> Trachea-->transports oxygen to tissues directly
Spiracles can NOT be closed
Respiratory Structure of Millipede
Spiracles-->Trachea
Spiracles
Largest tubes in the trachea
Connect outside through the openings in the body wall
Respiratory Structure of Grasshopper
Spiracles-->Trachea
CAN be closed (valve)
Respiratory Structure of Garden Spider
Book Lungs (anterior ventricle abdomen)
Tracheal system and spiracles (supplies oxygen faster than book lungs)
Book Lungs
Invaginations that form pockets in the abdomen
Folded into plates between which air can flow
Exchange between air and blood
Respiratory Structure of Snowbug
Pseudotrachea, spiracles, gills
Gas exchange with air (gills)
Pseudotrachea delivers oxygen to blood and then to tissues
Pseudotrachea
Tiny tubules from external spiracle to interior of appendage
Feeding of Crayfish
2 sets of antennae for taste
Paired mandibles
1st and 2nd maxillae
maxillipeds
Feeding of Grasshopper
Labrum, labium, mandibles, hypopharynx
Organs in abdomen for digestion
Locomotion of Crayfish
Walk underwater, swim with tail
Rapid backwards movements of swimming (uropods/telson)
Locomotion of Grasshopper
6 legs (5 segments)
Coxa, trochanter, femur, tibia, tarsus, wings
Jumping and walking
Excretion of Crayfish
Anus
Excretion of Grasshopper
Organs in abdomen
Sensory perception in Crayfish
Antennules and antennae (touch)
Maxillipeds (sensory)
Sensory perception in Grasshoppers
Compound eyes (movement)
Ocelli (light intensity)
Tympanum (sound vibrations)
Centipede structures
Head and trunk tagmata
Eyes- group of ocelli (not compound)
Antenna, jaw like mouth
Fangs, 1 pair of legs and spiracles per segment
Millipede structures
Head and trunk tagmata
Eyes- group of ocelli (not compound)
Antenna, jaw like mouth
2 pairs of legs per segment and 2 pairs of spiracles per segment--Tagmatization
Insect structures
Head, thorax, and abdomen tagmata
1 pair of antennae
3 pairs of thoracic legs
Usually have 2 pairs of wings
Compound AND simple eyes
Crustacean structures
2 pairs of antennae
Gills
Cephalothorax and abdomen tagmata
Appendages branch into 2 parts
Horseshoe Crab structures
Prosoma, Opisthosoma, Telson tagmatas
Chelicerae, Pedipalps, 4 pairs of legs, mouth
Book gills, Spines
Compound AND simple eyes
Garden Spider structures
Prosoma, Opisthosoma tagmatas
Compound eyes, chelicerae, pedipalps, 4 pairs of legs
Book lung slits, tracheal spiracle, spinnerets
Maxillae
In Grasshoppers and Horseshoe crabs
Used for handling food
Hypopharynx
Tongue like structure in Grasshopper
5 segments of Grasshoppers legs
Coxa
Trochanter
Femur (muscles)
Tibia (plantar surface when walking)
Tarsus (grasping and holding)
Tympanum
Sensory structure in grasshoppers that detects sound vibration
Carapace
Shield like sheet of exoskeleton found in Crayfish
Maxillipeds
Found in Crayfish
Sensory functions, handle food
Chelipeds
Large pincer found in Crayfish (1st pair of walking legs)
Walking Legs
In Crayfish and Horseshoe Crabs
Defense and catching/handling food
Swimmeret
In Crayfish
1st in male reproduction
2-5th Water circulation, carry eggs and young
Uropod
Swimming, egg production in Crayfish
2 tagmas of the Horseshoe Crabs/Spiders
Prosoma (anterior)
Opisthosoma (posterior)
Chelicerae
In Horseshoe Crabs and Spiders
Most anterior appendage, used to detect and manipulate food
Pedipalps In Horseshoe Crabs
Grasp onto carapace of female during mating
Gnathobases
In Horseshoe crabs
Spiny processes that tear up food and pass it to the mouth (at the end of the appendages)
Telson
Tail spine
Anchors Horseshoe Crab when digging
Also helps to turn the animal over
Pedipalps in Spiders
Sensory function, manipulate food, transfer sperm
What Phylums are Acoelomate?
Platyhelminthes (flat worms)
What Phylums are Pseudocoelomates?
Nematodes (round worms)
What Phylums are Coelomates?
Molluscs
Annelids
What Phylums are Hemocoel?
Arthopoda (coelom reduced relies on muscles for movement)
Circulatory system of Nematodes
No Specialized system
Pseudocoelom distributes nutrients and wastes around body
Reproduction of Nematodes
Sexual reproduction only (mostly seperate sexes)
Internal fertalization
Respiratory system of Nematodes
No specialized system
Cuticle permeable to gas and water
Segmentation of Nematodes
Unsegmented
