2. Appearance characteristics
Take Oratosquilla as an example: there is a movable trapezoidal frontal plate in the center of the front edge of the head breastplate, and there are movable eye joints and antenna joints in front. The abdomen is wide, * * * six segments, and finally a wide and short tail segment, with a ridge in the center of the back and strong thorns at the rear edge. The handle of the first antenna is slender and divided into three sections, and there are three touch whips at the end to control the sense of touch. The handle of the second antenna has two parts, with a touch whip and a rectangular scale. Mouth and jaw are very hard, divided into molars and incisors, both of which have dentate protrusions, which can cut off and grind food; The tentacles of the maxilla have three nodes, which are not significant and have sensory effects. The first jaw is small, the original limb has two segments, and the inner edge has bristles. The second jaw is thin and consists of four sections, with dense hairs on the inner edge. These two pairs of small jaws can help the big jaw tear up food. There are eight pairs of appendages in the chest, the first five pairs are jaw feet and the last three pairs are walking feet (just opposite to the three pairs of jaw feet and five pairs of walking feet of decapod animals). The first pair of jaws are slender, with flat distal ends and bristles; The second jaw foot is particularly powerful, with a flat end (finger joint) and six sharp teeth, which can match the marginal groove of metacarpal joint. It is a sharp weapon for preying on and defending the enemy, called grazing limbs; The third to fifth pairs of jaws are shorter than the first pair, and the ends are small claws. These appendages can send captured food into the mouth. All five pairs of jaws have no external limbs, but there are round upper limbs at the base.
