Concept explainers
To list: The appendages on the head of the crustacean.
Introduction: Animal kingdom is vast which is divided on the basis of the properties possessed by the animal species. Arthropods have segmented body parts which are called appendages, each having a specialized role.
Explanation of Solution
Arthropods are the invertebrate species that are evolved to having a segmented body and exoskeleton. The arthropods have specialized appendages and structures present on their head. The appendages found on the head are:
- Two Antennae
- Mandible (Jaw)
- Maxillae(Accessory Jaws)
These specialized structures present on the head helps them in sensing and locomotory activities.
To describe: The dissimilarity between crustaceans and other arthropods.
Introduction: Structural and morphological development in the life stages of arthropods are the basic parameters on which these species are classified. Arthropods and crustaceans have more similarities than differences which can be seen in their stages of life.
Explanation of Solution
The body of arthropod consists of three segments with a hard exoskeleton and jointed appendages; these appendages further make head, thorax, and abdomen. The head has two pairs of antennae, one pair of mandibles, and two pairs of maxillae.
Among the Phylum Arthropoda, only crustaceans have two pairs of antennae, which makes all the crustaceans distinctive among the Arthropods.
