Which of the following characteristic is unique to the phylum Cnidaria?
Nematocysts, the stinging cells found in cnidocytes, are the only item in this list that the cnidarians possess exclusively.
What characteristics of phylum Cnidaria are most important in their success?
Cnidarians have a unique feature: stinging cells called cnidocytes (NID-uh-sites). Each cnidocyte cell has a long, coiled, tubular harpoon-like structure, called a nematocyst (Greek root word nema meaning thread; Greek root word cyst meaning bag).
Which of the following is a characteristic of the phylum Cnidaria?
Phylum Cnidaria includes animals that exhibit radial or biradial symmetry and are diploblastic, meaning that they develop from two embryonic layers, ectoderm and endoderm. Nearly all (about 99 percent) cnidarians are marine species.
In what way does the phylum Platyhelminthes differ from the phylum Cnidaria?
Cnidarians are diploblastic, whereas Platyhelminthes are triploblastic. Platyhelminthes possess bilaterally symmetrical, soft, worm-like elongated bodies, whereas cnidarian possess radially symmetrical, soft, medusa-like or polyp-like body forms.
Which of the following are characteristic of the class Chelicerata?
This is a diverse class which belongs to a subphylum of the Arthropoda known as the Chelicerata. Chelicerata are characterized as having two distinct body regions, a cephlothorax and an abdomen. Chelicerates have six pairs of appendages, the first two pairs being mouthparts and the following four pairs being legs.
What are the five subphylum of arthropods?
Arthropods are traditionally divided into 5 subphyla: Trilobitomorpha (Trilobites), Chelicerata, Crustacea, Myriapoda, and Hexapoda. Myriapoda is divided into four classes: Chilopoda (centipedes), Diplopoda (millipedes), Pauropoda, and Symphyla. Millipedes were likely the very first animals to live on land.
Which of the following characteristics identify arthropods?
The important characteristics of arthropoda include:
- They possess an exoskeleton.
- They have jointed appendages.
- Their body is segmented.
- They are bilaterally symmetrical.
- They possess an open circulatory system.
What trait do all arthropods share?
All arthropods posses an exoskeleton, bi-lateral symmetry, jointed appendages, segmented bodies, and specialized appendages. The major arthropod classes can be separated by comparing their number of body regions, legs, and antennae.

Which of the following characteristics do Platyhelminthes and cnidarians have in common?
The major characteristic that these two animal phyla share is the presence of a gastrovascular cavity.
What are the characteristics of Chelicerata?
Common name: chelicerates, arachnids Like all arthropods, they have a segmented body and segmented limbs and a thick chitinous cuticle called an exoskeleton. Chelicerates have two body segments; a cephalothorax and an abdomen. They have no antennae, but have six pairs of appendages.
What one characteristic does every Chelicerata have?
Chelicerates have two body segments (tagmenta) and six pairs of appendages. Four pairs of appendages are used for walking and two (the chelicerae and the pedipalps) are used as mouthparts. Chelicerates have no mandibles and no antennae.
Which of the following are characteristics of the subphylum Chelicerata?
This is a diverse class which belongs to a subphylum of the Arthropoda known as the Chelicerata. Chelicerata are characterized as having two distinct body regions, a cephlothorax and an abdomen. Chelicerates have six pairs of appendages, the first two pairs being mouthparts and the following four pairs being legs.

This is a diverse class which belongs to a subphylum of the Arthropoda known as the Chelicerata. Chelicerata are characterized as having two distinct body regions, a cephlothorax and an abdomen. Chelicerates have six pairs of appendages, the first two pairs being mouthparts and the following four pairs being legs.
Which trait is unique to arthropods?
The distinguishing feature of arthropods is the presence of a jointed skeletal covering composed of chitin (a complex sugar) bound to protein. This nonliving exoskeleton is secreted by the underlying epidermis (which corresponds to the skin of other animals).
What characterizes members of phylum Platyhelminthes?
Characteristic features of Phylum Platyhelminthes
- Their body is dorsoventrally flattened.
- They exhibit bilateral symmetry.
- Also, they are triploblastic, with three germ layers.
- They do not have a body cavity and are acoelomate.
- The body is soft and unsegmented.
- They are mostly parasitic with a few free-living.
What organisms are in subphylum Chelicerata?
Most members of the subphylum Chelicerata belong to the class Arachnida, containing the spiders, scorpions, ticks, and mites. They are largely terrestrial arthropods, living beneath stones and logs, in leaf mold, and in vegetation, but there are some aquatic mites that live in fresh water and in the sea.

Which of the following are characteristics of animals within the phylum Platyhelminthes quizlet?
Which of the following is true of animals within the phylum Platyhelminthes? They have a simple circulatory and respiratory system, but do have a complex reproductive system.
What do all Platyhelminthes have in common?
The Platyhelminthes, both parasitic and free-living taxa, share a set of characters: they are nonsegmented acolomates without an anus, which lack respiratory and circulatory systems but possess an excretory system. In addition, all are hermaphroditic and asexual (mainly paratomy) and sexual reproduction are present.
