Horseshoe crabs are in subphylum Chelicerata because they have four pairs of walking legs, a pair of pedipalps, and a pair of chelicerae. Pedipalps control food, and chelicerae are pinchers that crush food. Horseshoe crabs also don't have mandibles, which are jaws, and they don't have antennae. They have two tagmata: cephalothorax and abdomen. All of these characteristics apply to organisms in subphylum Chelicerata, and so horseshoe crabs are in subphylum Chelicerata.

What are the organisms that belong to the subphylum chelicerata?
Organisms in the subphylum Chelicerata include spiders, scorpions, ticks, mites, and horseshoe crabs. They are characterized by having specialized appendages called chelicerae, which are used for feeding.
Characterize the animal from the subphyla chelicerata?
The subphylum Chelicerata is an offshoot of the phylum Arthropoda. This subphylum includes spiders, scorpions, ticks, mites, horseshoe crabs and many other diverse species. Animals classified under Chelicerata can be herbivores, predators, scavengers, parasites or detritivores.
What does chelicerata mean?
Chelicerata is a subphylum of the phylum Arthropoda. It contains organisms like spiders, ticks, and scorpions. Organisms in Subphylum Chelicerata have a cephalothorax and a posterior abdomen. They have six pairs of appendages on their cephalothorax: Chelicerae, pedipalps, and four walking legs. Chelicerae are pinchers that crush food, and pedipalps are appendages that control food. They do not have mandibles, which are jaws, and they don't have antennae, so organisms in Subphylum Chelicerata technically aren't insects.
What spider crab?
No its a crustationcrustaceans & arachnids are both arthropods(phylum) of the kingdom animalia, but a crustacean is a subphylum, while arachnids are a class of the subphylum chelicerata, so it's like they're they're a whole different category. Crabs are a class, malacostraca, of the subphylum, crustacean. As an interesting sidenote, certain"crabs" are not crabs or crustaceans at all; e.g., horseshoe crabs are a class, merostomata, of the same subphylum, chelicerata, as the arachnids, so they are, in fact, a closer relation to arachnids than to crustaceans, kind of like cousins.CRABKingdom: AnimaliaPhylum: ArthropodaSubphylum: CrustaceaClass: MalacostracaOrder: DecapodaSuborder: PleocyemataInfraorder: BrachyuraARACHNIDKingdom: AnimaliaPhylum: ArthropodaSubphylum: ChelicerataClass: Arachnida
What are the animals included in the phylum chelicerata?
The subphylum Chelicerata constitutes one of the major subdivisions of the phylum Arthropoda, and includes horseshoe crabs, scorpions, spiders, mites, harvestmen, ticks, and Solifugae. The chelicerata originated as marine animals, possibly in the Cambrian period, but the first confirmed chelicerate fossils, eurypterids, date from 445 million years ago in the Late Ordovician period. The surviving marine species include the four species of xiphosurans (horseshoe crabs), and possibly the 1,300 species of pycnogonids (sea spiders), if the latter are chelicerates. On the other hand, there are over 77,000 well-identified species of air-breathing chelicerates, and there may be about 500,000 unidentified species.
Are crabs arrachnids?
The class Arachnida includes animals with four pairs of legs. So mites, scorpions, false scorpions, harvestmen and vinegarones are all in the same class as spiders. Crabs are Crustacea. The only link between them is that both classes are arthropods. Sea Spiders are in a separate class altogether.Confusion and argument has raged over the position of Horseshoe Crabs. My understanding is that they are now generally accepted as arachnids
What arthropod class has exactly 8 legs?
Chelicerata, containing spiders, scorpions, harvestmen, mites, ticks, sun/camel spiders and horseshoe crabs, among others.
Where are horseshoe crabs born?
Horseshoe crabs are born (hatch) in the ocean.
Are insects in the category of animals?
Insects are definitely members of the animal kingdom. The animal kingdom is broken down into groups called Phyla. The Phylum insects are classified in is Arthropoda (root words arthro- (joint) and pod- (foot or leg) meaning "jointed leg"). Insects are further classified in Subphylum Hexapoda (root words hexa- (six) and pod- (feet or leg) meaning "six legs") and Class Insecta. Other arthropods include Subphylum Chelicerata with Class Arachnida (spiders and scorpions), Class Merostomata (horseshoe crabs), Subphylum Myriapoda with Class Chilopoda (centipedes) and Class Diplopoda (millipedes), Subphylum Crustacea with Class Malacostraca (lobsters, crabs, shrimp), just to give a few examples.
Are horseshoe crabs related to regular crabs?
no//////////////////horseshoe crabs are related to spiders and scorpions.. WEIRD RIGHT!!
What problems do horseshoe crabs have?
their horseshoe crabs so everyone makes fun of them
Are horseshoe crabs a problem?
