What are the 2 key characteristics that all arthropods share in common? +Segmented bodies +Jointed appendages
What is the special skeleton of arthropods? +Possess a hard exoskeleton (bo xuong ngoai) made by chitin and protein that is secreted by and remains fused to the epidermis
What is the function of exoskeleton? +A continuous structure with overlapping folds. ( nep gap) allowing body to bend and the appendages( phan phu) to move. +Provides support for the body , provides an anchor for muscle attachment +protect the animals from predators and impedes waterloss
Do arthropod has coelom? Yes it is
Characteristics of arthropods +The main body cavity is a Hemocoel comprising part of the Open Circulatory System +The nervous system is like annelids, consisting of the dorsal brain and a single ventral nerve cord.
The specialized respiratory organs of athropods Varying from Gills in crustaceans, to Book Lungs in arachnid, to Tracheae and Spiracles in insect
The specialized excretory organs of arthropods for eliminating metabolic waste? The Malpighian tubules found in insect.
Major innovation of arthropods? +Bilaterally symmetry, three primary germ layers, a true coelom and segmentation +2 key elements: Jointed appendages(used for walking, flying feeding, reproducing, and sensing the envi) and an exoskeleton
Subphylum Myriapoda includes classes and animals? +Chilopoda (Centipedes) +Diplododa (Millipedes)
The traits and characteristics of Chilopoda (Centipedes)? +Cylinical body divide into head and segmented trunk +One pair of legs per body segment +One pair of antennae ( rau) +Poison fangs( rang nanh) absent;teresstrial
The characteristics of Diplopoda +Cylinical body divide into head and segmented trunk +2 pairs of legs per body segment +One pair of antennae +poison fangs absent;terrestrial
Subphylum Crustacea includes? +Malacostraca( Crayfish, lobster, crabs...)
What are the characteristics of Malacostraca class ? +2 pair of antennae +Biramous appendages +one pair of madibles (ham duoi) +Two pair of maxillae (xuong ham) +marine, freshwater, or terrestrial
Subphylum Hexapoda includes? +Insecta (Insects)
What are the characteristics of insecta class ? +body divided into head, thorax (nguc), and abdomen (bung duoi) +Three pair of legs on thorax +one pair of antennae +Primarily teresstrial
special about anthropods? The first animal to inhabit land, predating other familiar ancient The first animal to fly
Characteristics of centipedes? +Carnivorous predator that feed on worms and insect +body is divided into head and a trunk. +one pair of legs per body segment + A single pair of antennae on the head, and a pair of appendages modified into poison fangs.
Characteristic of Millipedes ? +Slow, docile herbivores feed on vegetation. +prefer dark, moist areas +Their clindrical body is divided into a head and a multi-segmented trunk + Two per of legs per body segments +single pair of antennae without poison fangs .
Characteristics of Crayfish? + Divided into two main regions ,The cephalothorax and the abdomen +appendages are present on both regions, +Rostrum,a pair of stalked, compound eyes, and 2 pairs of antennae +The longer pair is antennae, shorter is antennules
What organ does crayfish use for defense purpose and capturing killing prey? Cheliped.
What are the characteristics of Insects? +3 pairs of uniramous (Unbranched) walking appendages +1 pair of antennae +3 distinct body regions: Head, thorax, and abdomen
What are the evolution that allowed insects to thrive despite the challanges of a terrestrial environment +Stronger support system and stronger walking appendages to overcome the forces of gravity +waxy(sap) cuticles( vo) built to withstand the osmotic (tham thau) of dry air, yet adapted for gas exchange
Continue of evolutin in insects +Ability to fertilize eggs internally to prevent desiccation( su kho rao) of exposed gametes +Specialized respiratory, excretory, and digestive structures modified to conserve water +appendages modified into wings to take advantage of aerial habitats
