What are the three Chelicerate groups?

Chelates are divided into three categories (Merostomata, Arachnida, and Pycnogoida). The Merostomata class, including the horseshoe crab, Limulus, has been the subject of extensive neurobiological research.

What are chelicerate arthropods?

Chelicerata is a branch of the phylum Arthropoda that includes animals such as Spiders, scorpions, harvesters, mites and ticksLike all arthropods, they have a segmented body with segmented limbs and a thick chitinous cuticle called an exoskeleton. Chelicerates have two body parts; cephalothorax and abdomen.

What are the two types of chelicerae?

The two groups of chelicerae are Ocean, Horseshoe Crab (Xiphosura) and Sea Spider (Pycnogonida)which together make up less than 2% of the diversity of modern chelicerae.

What are Chelicerates named after?

Chelates are arthropods, with their feeding appendages are called cheliceraeThe chelicerae are a pair of special appendages that appear in front of the mouth. These appendages have become part of the mouth, and in spiders, the chelicerae form fangs.

Why are crustaceans so successful?

Crustaceans are Highly diverse and successful animal population…the great flexibility of this structure, and the general success of the arthropod program (exoskeletons and articulated limbs), make them very successful as a group of animals.

What are the three main body areas of crustaceans?

Crustaceans are usually grouped by the number of segments they have in each body area (head, chest and abdomen). The only common appendages of all crustaceans are two pairs of antennae. All others vary by group.
