Which organism would be classified as an arthropod?
Phylum Arthropoda is the most diverse and abundant phylum of animals, estimates range from 2 to 10 million species fall into Arthropada. All arthropods have an exoskeleton made of chitin (pronounced kite-en) which are strong fibers of long nitrogen-containing sugars. Additionally arthropods are the first animals to evolve jointed appendages, hence their name (arthro = jointed, poda = foot or appendage). Arthropods are coelomate, meaning they have an open circulatory system, but their organ systems are well developed. Examples of arthropods range from lobster, crabs, shrimps, and crayfish, to insects, arachnids (spiders, scorpions, mites, and ticks), millipedes, and centipedes.
What did the first arthropods on land eat?

How do arthropods give birth?
Arthropods include an incredibly diverse group of taxa such as insects, crustaceans, spiders, scorpions, and centipedes. There are far more species of arthropods than species in all other phyla combined, and the number of undescribed species in the largest assemblage of arthropods, the insects, probably numbers in the tens of millions. Members of the phylum have been responsible for the most devastating plagues and famines mankind has known. Yet other species of arthropods are essential for our existence, directly or indirectly providing us with food, clothing, medicines, and protection from harmful organisms.
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.
Where did the first arthropods appear more than 600 million years ago?
The sea
The first land animals belong to which group?

As you list animals from simple to complex the first animals with jointed appendages would be the?
arthropods
The first land animals belong to which group A arthropods B echinoderms C mollusks D vertebrates?
A. Arthropods
Which subphyla of arthropoda is caracterized by animals lacking antennae?
The subphyla of arthropoda that does not have antennae is chelicerata. Chelicerates, which include spiders and scorpions, are missing the first segment of nerve ganglion which controls antennae in other arthropods.
During the Silurian period the first animals to adapt to life on land were?
Arthropods ( EARTH SCIENCE )
What were the first animals to invade the land?
The first animals to successfully invade land were likely arthropods, such as early ancestors of insects, spiders, and scorpions. These creatures adapted to terrestrial environments by developing structures like jointed legs and exoskeletons to support themselves outside of water. They played a crucial role in the colonization of land and paving the way for subsequent terrestrial animal life.

What is a eurypterid?
Its the largest bug, kinda like a sea scorpion and is known to be taller than man! -- The eurypterids match the above description. Also, they first appeared in the Silurian period along with corals and early land plants.
What period did animals first begin to invade the land?
If you mean animals as in insects (arthropods), they came in around the Devonian period of the Paleozoic era If you mean animals as in fish, amphibians etc then they came in at the same time as the arthropods
What were the dominant organisms living during the carboniferous period?
The Permian period was about 280 to 248 million years ago. The dominant organisms in this time period were the amphibians because they were abundant. However, there were other organisms, such as synapsids, fish and invertebrates.
When did the first land plants and animals appear in the fossil record?
The first plants with spores, which indicates that they were land plants, appeared in the Middle Ordovician period, about 470 million years ago. First records of tetrapods, or land animals, show up in the fossil record around 370 million years ago.
