What makes a dragonfly in the Arthropod Insects phylum?
Its three-parted body, its antennae, and wings
What is the Common function of Arthropod antennae?
Antennae on arthropods perform sensory functions. In insects they detect moisture, temperature, and have olfactory functions; in crustaceans there are chemical receptors which function similar to our taste and smell for molecules drifting in seawater. There are also sensory receptors in many arthropod antennae which detect the amount of force from muscle action and the degree of bending and thus provide the touch sense. Some butterflies have a solar compass in their antennae, used for navigation.
An arthropod with four pairs of walking legs no antennae and two body parts?
The answer is very simple. an octopus of course It has no antannae but do own an exoskeleton,
What is an arthropod that has no atennae?
Spiders are arthropods that do not have antennae. They rely on other sensory organs, such as their pedipalps and hairs, to detect their surroundings and prey.
Which arthropod group has no antenna?
The Arachnid class is an example of an arthropod group characterized by possessing two main body segments, eight legs, but having no antennae. All arthropods except chelicerates and proturans have antennae. (The chelicerates include arachnids, horseshoe crabs, and sea spiders.)
How is the skeleton of an arthropod diffrent from your skeleton?
Arthropod skeletons differ from ours in that they are external, or exoskeletons. By contrast ours are internal, or endoskeletons.
How do crustaceans arachnids and centipedes and millipedes differ?
A crustacean is an arthropod that has two or three body sections, five or more pairs of legs, and two pairs of antennae. Arachnids are arthropods with two body sections, four pairs of legs, and no antennae. Arachnids are arthropods with two body sections, four pairs of legs, and no antennae.
What arthropods have two pairs of antennae?
Crustaceans are arthropods characterized (and classified) by their biramous (branching) appendages, which include two antenna pairs. The smaller set are referred to as antennules. All other arthropod groups have one pair except chelicerates and proturans, which have no antennae.
What insect has two sets of antennae?
No insect has two sets of antennae since Insects class membership is characterized by just one pair of front-located sensors. Scientists include insects within the arthropod phylum. Within that phylum, arachnids, chilopods and diplopods lack antennae whereas crustaceans have two sets.
Where are an arthropod's antennae located?
For those arthropods with antennae, they will appear on the head. The location and count depends on the subphylum or group; for trilobites, hexapods (including insects) and myriapods they are located on the first body segment; for crustaceans which have two pairs they are located on the first and second body segments, with the smaller pair called antennules. Arachnids including spiders and scorpions have no antennae.
What is the function of the isopod's antennae?
Antennae on arthropods perform sensory functions. In insects they detect moisture, temperature, and have olfactory functions; in crustaceans there are chemical receptors which function similar to our taste and smell for molecules drifting in seawater. There are also sensory receptors in many arthropod antennae which detect the amount of force from muscle action and the degree of bending and thus provide the touch sense. Some butterflies have a solar compass in their antennae, used for navigation.
What are the sense organs on the head of the arthropod used for?
The sense organs on the head of an arthropod, such as compound eyes and antennae, are primarily used for sensory perception. Compound eyes enable them to detect light and movement, providing a wide field of vision, while antennae serve as taste and smell receptors, helping arthropods navigate their environment, find food, and communicate with others. These organs are crucial for survival, aiding in predator avoidance and mate selection.
