Arthropod Features
26.1 Arthropod Characteristics
ArthropodsChapter 26
Arthropods are segmented invertebrates with bilateral symmetry, coelomate body cavities, and protostome development.
Arthropods have exoskeletons with jointed appendages.

Segmentation
Arthropods
The head has mouthparts for feeding and various types of eyes.
The thorax is the middle body region to which legs and wings are attached.
The abdomen is the posterior end of the abdomen and bears additional legs and contains digestive structures and the reproductive organs.

Arthropods obtain oxygen by using one of three structures—gills, tracheal tubes, or book lungs.
Circulation
Their circulatory systems transport nutrients and remove wastes.

Excretion
Cellular wastes are removed from the blood through Malpighian tubules.
Malpighian tubules are attached to and empty into the gut, which contains the undigested food wastes to be eliminated from the body.

The strength of muscle contraction depends on the rate at which nerve impulses stimulate muscles.
The muscles are attached to the inner surface ofthe exoskeleton on both sides of the joint.

Crustaceans
Most are aquatic and have two pairs of antennae, two compound eyes that can be on the tips of slender movable stalks, and mandibles for chewing.
Arthropods
Crustaceans possess branched appendages and have a free-swimming larval stage.

Most crustaceans, such as crayfishes, lobsters, and crabs, have five pairs of legs.
Arthropods
Behind the next four pairs of walking legs are the swimmerets, appendages that are used for reproduction and as flippers during swimming.
The first pair oflegs—the chelipeds—has large claws adapted to catch and crush food.

Spiders and Their Relatives
Most arachnids have two body sections—a cephalothorax and an abdomen—and six pairs of jointed appendages.
Arthropods
An arachnid’s most anterior pair of appendages is modified into mouthparts called chelicerae.
The second pair of appendages is called the pedipalps.

Spiders are capable of constructing only specific kinds of webs.
The spider ingests the softened food.
A spider secretesdigestive enzymes onto its prey.

Arthropods
The male inserts the sperm into the female.
The female lays her eggs in a cocoon spun of spider silk.
There can be as many as 100 eggs in one cocoon.
26.2 Arthropod Diversity
A male spider stores sperm in a cavity on his pedipalps.

Horseshoe Crabs
Arthropods
Horseshoe crabs have remained unchanged since the Triassic Period more than 200 million years ago.
The chelicerae, pedipalps, and the next three pairs of legs are used for walking and getting food from the bottom of the sea.
They feed on annelids, mollusks, and other invertebrates.
