Amblypygi

Amblypygi is an order of arachnids known as tailless whip scorpions. Its members have flattened bodies, spiny grasping pedipalps, and elongated sensory front legs.

Raptorial pedipalp: A modified appendage used to seize and hold prey. Amblypygids use their spiny pedipalps to capture prey and defend themselves.
Arachnid: A chelicerate arthropod with four pairs of walking legs and no antennae. Amblypygi is one order within this broader group of joint-legged animals.
Phrynus marginemaculatus: A small Caribbean tailless whip scorpion studied for its social behavior. This species provides evidence that some amblypygids recognize and tolerate familiar individuals.
Thelyphonida: An arachnid order of whip scorpions with a long, whip-like tail. Unlike Amblypygi, thelyphonids possess a conspicuous tail and lack antenniform legs.
Antenniform leg: An elongated sensory leg that probes the surroundings rather than supporting locomotion. The first pair of amblypygid legs detects nearby surfaces and prey through touch.
Chelicerata: A major arthropod group that includes arachnids and horseshoe crabs. Amblypygids inherit chelicerae and other traits from this larger lineage.
Damon diadema: A large African tailless whip scorpion with very long sensory legs. Its conspicuous proportions make it a recognizable example of amblypygid anatomy.
Schizomida: A small arachnid order whose members often have a short, segmented flagellum. Schizomids are close relatives, but their flagellum and body proportions differ.
Sensory bristle: A hairlike sensory structure that detects mechanical or chemical stimuli. Sensory bristles on the antenniform legs help amblypygids map nearby space.
Chelicera: The first pair of appendages in chelicerates, used for feeding or prey handling. Amblypygid chelicerae manipulate food after the pedipalps capture it.
