Are spiders a chelicerate?
yes
What is a xiphosuran?
A xiphosuran is a member of the order Xiphosura, a marine chelicerate commonly known as a horseshoe crab.
What is a xiphosauran?
A xiphosauran is a member of the order Xiphosura, a marine chelicerate commonly known as a horseshoe crab.
What is the function of chelicerae in chelicerates?
Chelicerae are specialized mouthparts found in chelicerates, such as spiders, scorpions, and horseshoe crabs. Their primary function is to grasp and manipulate food, often serving as fangs or pincers that help in feeding and defense. In many species, they also play a role in subduing prey, injecting venom, or processing food before ingestion. Overall, chelicerae are essential tools for survival and feeding in chelicerate species.
What structures of chelicerates are analogous to the antennae of chilopods and other mandibulates?
A chelicerate does not have antennae because it is missing the nerve bundle that would control that structure. Instead, chelicerates use setae to detect changes in air currents and provide equivalents to smell and taste.
Why is a crab an amphibian?
Neither. All crabs are crustaceans.Amphibians are cold-blooded, lay eggs and have an internal skeleton with soft skin.Crustaceans are cold blooded, lay eggs and have an external skeleton (shell).
Are trilobites related to horshoe crabs?
Yes!! a very astute and clever question!!! Trilobites and King/Horseshoe crabs share a proud lineage extending many millions of years. Back in the pre-triassic period, scientists believe the Genus Horseshoidae began in the deep Vandarin Delta -- what we now call the southern portion of the gobi desert - in the dark liquid mud they teemed in their millions. they fed on squidlike creatures whose delicate fossils scientists today call Mantissa. So the short answer to your question is YES! and YES!! both are all EDIBLE!
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.
What type of animal is the spider?
A spider is not an insect (insects have three body parts and six legs). Spiders are invertebrates, they have have eight legs and two body parts, silk spinning glands called spinnerets (but not all spiders spin webs), they are oviparous and can have six or eight eyes. Most spiders have fangs, through which venom is ejected. To learn more about spiders look for their following taxonomic classification: - Kingdom: Metazoa - Phylum: Arthropoda - Class: Arachnida - Order: Araneae
IS a horseshoe crab a crustacean?
A horseshoe crab actually is not a Crustacean. Although it is a crab, it is part of the Subphyla Chelicerate because it has a very small set of appendages just above the mouth called Chelicerae. It is more similar to spiders and other Chelicerates than Crustaceans.
How many types of spiders are there?
Spiders (order Araneae) are air-breathing chelicerate arthropods that have eight legs, and chelicerae modified into fangs that inject venom. Spiders are found world-wide on every continent except for Antarctica, and have become established in nearly every ecological niche with the exception of air and sea colonization. As of 2008, approximately 40,000 spider species, and 109 families have been recorded by taxonomists. However, there has been confusion within the scientific community as to how all these genera should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.
What are tarantula spiders?
These are arachnids. They are a large spider.Tarantulas are slow and deliberate movers, but accomplished nocturnal predators. Insects are their main prey, but they also target bigger game, including frogs, toads, and mice. The South American bird-eating spider, as it name suggests, is even able to prey upon small birds. They have a venom but it is not harmful to humans, it is much like a bee sting.
