Arthropods Jointed-legged invertebrates
Arthropod Characteristics Chitinous exoskeleton Paired-jointed appendages Growth with ecdysis (molting) Open circulatory system Complete digestive tract
Exoskeleton Major reason for success! Provides Support Protection Prevention of dehydration Sites for muscle attachment
Metamorphosis Change body form from immature (larval) stages to adult forms Reduces competition between stages for Food Living space
Taxonomy of Arthropods 4 subphyla Trilobitomorpha (all extinct) Chelicerata Crustacea Uniramia
Chelicerata Horseshoe crabs Spiders Mites Ticks Scorpions
Crustacea Shrimp, lobsters, crayfish Fairy shrimp, brine shrimp Water fleas Barnacles
Uniramia Class Diplopoda (millipedes) Class Chilopoda (centipedes) Class Hexapoda (insects)
Nervous System Johnstons organs (hearing - on antennae) Tympanic organs (hearing – on legs or body) Compound eyes (facets – ommatidia – fused) Simple eyes (ocelli)
Economic Impact of Arthropods 1.Name one effect each major group has on mankind (good or bad). 2.For insects, list 4 good things that they do and 4 bad things that they are responsible for.
Arthropods Jointed-legged invertebrates. Arthropod Characteristics Metamerism with tagmatization Chitinous exoskeleton Paired-jointed appendages Growth.
9. Arthropods Largest and most successful phylum in the animal kingdom. 85% of all animals! Largest and most successful phylum in the animal kingdom.
ARTHROPODS HOLT CH. 29 PG ARTHROPOD CHARACTERISTICS Segmented body.
An arthropod is an invertebrate with an exoskeleton, a segmented body, and jointed legs.

Arthropods BIOL Phylum Arthropoda Cheliceriformes –Horseshoe Crabs –Arachnids: spiders, scorpions, ticks, mites Myriapoda: millipedes and centipedes.
Sponges are sessile and have a porous body and choanocytes Sponges, phylum Porifera, live in both fresh and marine waters Sponges lack true tissues and.
AATHROPODA SUBPHYLUM CHELICERATA Defining Characteristics chelicerates have segmented bodies with jointed limbs, all covered in a cuticle made of chitin.
Arthropoda Tavia Sin and Kelly Chen The most successful of all animal phyla
This PowerPoint presentation was developed to coincide with an eighth grade science textbook. This PowerPoint presentation is used to introduce and teach.
CHAPTER 26 Sponges, Cnidarians, Flatworms, and Roundworms.
Arthropods The Armored Achievers pp Arthropod Largest phylum with 1 million species (3/4 of all animals on earth) Segmented bilateral symmetry.

Simple Invertebrates Sponge Sponges are asymmetrical and do not have real tissue or organs. Cnidarians have radial symmetry and have a mouth, tentacles,

INVERTEBRATES CH Kingdom Animalia Major Characteristics= eukaryotic, multi-cellular, heterotrophic, lack a cell wall Invertebrates Include 95-97%
Phylum Arthropoda. Several million species. Hard exoskeleton.
INVERTEBRATES About 97 percent of all animals are invertebrates.
Insects Ms Shader. Insect Project 20 insect species for an ‘A’, 15 for a ‘B’ and 10 for a ‘C’ Labels must have common name on each –Plus place found and.
