Setae in oligochaetes (a group including earthworms) are largely composed of chitin. [1] They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. [2] Diptera setae are bristles present throughout the body and function as mechanoreceptors.
Trichobothria (singular trichobothrium) are elongate setae ("hairs") present in arachnids, various orders of insects, and myriapods that function in the detection of airborne vibrations and currents, and electrical charge. [1] In 1883, Friedrich Dahl observed that they were deflected by the sound waves from a violin and labelled them 'hearing ...
In fact, spiders and other arthropods have modified their cuticles into elaborate arrays of sensors. Various touch and vibration sensors, mostly bristles called setae, respond to different levels of force, from strong contact to very weak air currents. Chemical sensors provide equivalents of taste and smell, often by means of setae. [33]

The largest lobster on record was 3 feet 6 inches long and weighed 44 pounds and 6 ounces. However, they are typically around 8-24 inches in length and weigh between 1-9 pounds. Most lobsters sold ...
The two main groups of squat lobsters share most features of their morphology. They resemble true lobsters in some ways, but are somewhat flattened dorsoventrally, and are typically smaller, ranging from 0.7 to 3.5 inches in length.
Lobster bisque, lobster stock, and lobster consommé are made using lobster bodies (heads), often including tomalley. In Maryland and on the Delmarva Peninsula , the hepatopancreas of the blue crab is called the "muster" or "mustard", probably because of the yellow color, which is not the bright yellow of regular prepared yellow mustard , but ...
The decapod (crustaceans, such as a crab, lobster, shrimp or prawn) is made up of 20 body segments grouped into two main body parts: the cephalothorax and the pleon . [1] [2] Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail:
