| 41. | Many arthropods have sclerites, or hardened body parts, which form a stiff exoskeleton made up mostly of chitin.
|
| 42. | The ventral side of the idiosoma bears sclerites, and the gonopore is located between the fourth pair of legs.
|
| 43. | The skeleton of " Gorgonia ventalina " contains hard structures known as sclerites which are unpalatable to predators.
|
| 44. | These sclerites are covered with many hairs and short spines directed backward, which also assist its movements on the host.
|
| 45. | All of the sclerites were tiny : the palmates ones ranged from to in length, and the cultrates from to.
|
| 46. | Sclerites interpreted as its mouthparts have since been assigned to a new priapulid worm genus, " Omnidens ".
|
| 47. | The anterior of " Fuxianhuia " is encased in an oval sclerite, from which two stalked eyes emerge.
|
| 48. | Its mollusc shell is unique, because " Cobcrephora " was described on the basis of isolated phosphatic sclerites.
|
| 49. | However, these additional sclerites, and even the clamps themselves, are lacking in certain members of the family Protomicrocotylidae.
|
| 50. | It is formed by the prothorax, mesothorax and metathorax and comprises the pleuron, a lateral sclerite of the thorax.
