Typically, paired appendages around the mouth are used for collecting and handling food and are usually specialized in accordance with the particular diet of the animal. For example, the insect family Aphididae has mouthparts adapted for piercing vegetation and sucking out plant juices.

What is the name of a pair of appendages near the insect's mouth?
Insect mandibles are a pair of appendages near the insect's mouth, and the most anterior of the three pairs of oral appendages (the labrum is more anterior, but is a single fused structure). Their function is typically to grasp, crush, or cut the insect's food, or to defend against predators or rivals.
What is the purpose each type of crustacean appendage?
The appendages change both their form and their function during the life cycles of most crustaceans. In most adults the antennules and antennae are sensory organs, but in the nauplius larva the antennae often are used for both swimming and feeding.
What are mandibles used for?
The mandible (from Latin: mandibula or mandĭbŭ-lum, a jaw) of an arthropod is a pair of mouthparts used either for biting or cutting and holding food. Mandibles are often simply called jaws. Mandibles are present in the extant subphyla Myriapoda (millipedes and others), Crustacea and Hexapoda (insects etc.).
What is the function of a Chelicera?
The first pair, the chelicerae, often have claws or fangs. They are used to capture prey (spiders), transport a spermatophore (sunspiders, some mites and ticks), produce sounds (sunspiders, some spiders), cut strands of silk (web-dwelling spiders), and produce silk (pseudoscorpions).
What specialized paired appendages do the praying mantis use to handle food?
Maxillae — paired appendages with the following parts: Cardo — basal sclerite that articulates with the head capsule. Stipes — medial sclerite that supports a sensory palp. Galea and Lacinia — distal sclerites that act as fork and spoon to manipulate the food.
Do insects feel pain?
Over 15 years ago, researchers found that insects, and fruit flies in particular, feel something akin to acute pain called “nociception.” When they encounter extreme heat, cold or physically harmful stimuli, they react, much in the same way humans react to pain.
What are three functions of appendages in the crustacean?
Crustacean appendages are variously modified among taxa for locomotion (walking, swimming), feeding, grooming, respiration, sensory reception, reproduction, and defense.
Which set of appendages are used for walking?
The Order Decapoda have five pair of walking legs, and include the familiar crabs, lobsters, and crayfish. The first pair of appendages are usually modified as antennae. Crustaceans have two pair of antennae.
Why are crustaceans important to our marine ecosystem?
Crustaceans have an important role in the ecosystem as they serve as vital food sources for both marine animals and humans. Small crustaceans can recycle nutrients as filter feeders, and larger crustaceans can act as a food source for large aquatic mammals.
What are appendages in insects?
Insect appendage anatomy. Despite specializations into multiple appendage types, such as antennae, legs, and mouthparts, modern insect appendages are considered to be serially homologous structures that retain anatomical and developmental aspects of their common evolutionary origin (Boxshall, 2004, Snodgrass, 1935).
How are insect mouthparts used for feeding?
The most basic mouthparts, from which all other types have evolved, are for chewing. Predators such as the lady beetle have chewing mouthparts, but the mandibles have evolved into long, pointed appendages they can also use to grasp prey. Chewing mouthparts allow the insect to bite or rasp off and swallow solid food.
What is the function of maxilla in cockroach?
Maxillae (singular Maxilla) are part of an insect's mouthparts. The maxilla are paired and arranged behind the mandibles. Maxillae usually end in a sharp point and so the maxillae act like pincers. They are used to hold and manipulate food so that it can be chewed or sliced by the mandibles.
What are chelate appendages?
Chelicerae are chelate appendages that are used to grasp food. For example, in horseshoe crabs, they are like pincers, whereas in spiders, they are hollow and contain (or are connected to) venom glands and are used to inject venom to disable prey prior to feeding.
How are chelicerae used in feeding by a spider?
The chelicerae are a spider's jaws. They are located on the very front of a spider's cephalothorax. Every Kentucky spider has a pair of chelicerae, and they are tipped with fangs. Chelicerae are filled with muscles, and are used to hold prey while the spider injects venom.
What do the Chelicerates use for excretion?
To conserve water, air-breathing chelicerates excrete waste as solids that are removed from their blood by Malpighian tubules, structures that also evolved independently in insects.
