Arthropods• “joint-foot”• Have jointed appendages modified for
different functions• Largest phylum of animals
![Page 3: Kingdom Animalia Phylum Arthropoda](https://reader033.vdocuments.us/reader033/viewer/2022061610/56816589550346895dd8482c/html5/thumbnails/3.jpg)
Exoskeleton
• Hard, protective exterior skeleton• Made of protein & chitin• Flexible for joint movement• Doesn’t grow w/ animal, must shed old to
produce new= molting• Limits size of arthropods• Highly developed nervous system

Subphylum- Crustaceans
• Include barnacles, krill, shrimps, lobsters, crabs
• 3 main body regions– Head– Thorax– Some have fused head/thorax = cephalothorax– Abdomen
• Each body segment has pair of appendages
![Page 7: Kingdom Animalia Phylum Arthropoda](https://reader033.vdocuments.us/reader033/viewer/2022061610/56816589550346895dd8482c/html5/thumbnails/7.jpg)
Crustaceans, cont’d
• Appendages include:– Sensory antennae– Mandibles/maxillae: for feeding– Walking legs– Legs modified for swimming, reproduction, feeding, and
defense• Gas exchange through body or using gills• Vary in reproduction• Most have separate sexes• Most fertilization internal
![Page 8: Kingdom Animalia Phylum Arthropoda](https://reader033.vdocuments.us/reader033/viewer/2022061610/56816589550346895dd8482c/html5/thumbnails/8.jpg)
Types of Crustaceans• Krill– Pelagic, shrimp-like animals– 3-6 cm long– Filter-feeders, feed primarily on zooplankton– Most bioluminescent– Extremely important feed animal. Primary food of
several whale species

• Barnacles– Sessile (don’t move)– Can cause problems for ships by attaching to
hulls & causing increased friction– Some attach to whales and large fish

More Crustaceans
• Decapods (“ten feet.”)• Shrimps, lobsters, crabs• Largest in number & size• 5 pairs walking legs usually w/ claws on first• Shrimps & lobsters: distinct & elongate
abdomens• Crabs: small abdomen, broad cephalothorax,
highly mobile

Chelicerates-Subphylum• Include spiders, ticks, scorpions, horseshoe crabs
![Page 13: Kingdom Animalia Phylum Arthropoda](https://reader033.vdocuments.us/reader033/viewer/2022061610/56816589550346895dd8482c/html5/thumbnails/13.jpg)
Horseshoe Crabs• Not true crabs• Live in shallow coastal
waters• 3 parts to body:– Cephalothorax-largest part of
body, obvious appendages– Abdomen-smaller, contains
gills– Telson- long spike, used for
steering & defense• Can walk or swim• Males smaller than females

6 pairs of appendages
Chelicerae(ka-LIS-er-ree): modified for feeding, replaces mouthparts
