pedipalps
A squid has ten appendages. A squid's appendages are arranged in five pairs. The longest pair of appendages, the fourth pair, are called tentacles or feeder arms.
Spiders are in the phylum arthropoda, but they are in there own subphylum called Chelicerata, because they are quite different from other arthropods. The name chelicerata comes from a unique pair of appendages called chelicera.
Crabs, and the clawlike appendages are called chilipeds.
A pedipalp is basically the appendages that you see on spiders (that look like antennae) or scorpions (that look like pincers) or almost any other anthropod.each of the second pair of appendages attached to the cephalothorax of most arachnids. They are variously specialized as pincers in scorpions, sensory organs in spiders, and locomotory organs in horseshoe crabs.
The crustaceans are arthropods with biramous (branching) appendages, including a larger and smaller pair of antennae, the smaller ones being referred to as antennules.
Arthropods are invertebrates with jointed appendages. They include insects, spiders, crustaceans (like crabs and shrimp), and centipedes. Their segmented bodies with exoskeletons provide support for their appendages.
Prawns have five pairs of appendages on their body. These include two pairs of antennae, one pair of mandibles, one pair of maxillae, and three pairs of walking legs.
The Sow bug has a pair of appendages, called the uropod's, that project from the rear of the animal. These are a sensory and defensive in function.
3 pair, like all insects. Arachids (Spiders) have 4 pair.
Antennae and compound eyes are appendages that insects have and that arachnids lack.Specifically, insects have three (3) pairs of legs and one (1) pair of antennae. In contrast, spiders have four (4) sets of legs and no antennae. They also see through a series of singular, lensed eyes whereas insects have compound eyes.
