Chelicerates are characterized by a pair of chelate preoral appendages and a body divided into two tagmata, the prosoma and opisthosoma. |
|
The chelicerate body plan is characterized by two tagmata, the prosoma, including head structures, and the opisthosoma. |
|
Cheliceramorphs are distinguished by having a body divided into two main divisions, technically called the prosoma and the opisthosoma. |
|
Of the eight specimens, three are almost complete and five consist only of the prosoma and part of the opisthosoma. |
|
The upper or dorsal side of the prosoma is equipped with two prominent kidney-shaped compound eyes, and in the middle a pair of small ocelli or simple eye-like sense-organs. |
|
One central pair of eyes and from zero to five lateral pairs are set into the dorsal carapace that covers the prosoma. |
|
The three major regions that form the body, from front to rear, are the prosoma, the mesosoma, and the metasoma. |
|
The prosoma has six segments, each with a pair of appendages. |
|
Multiparous Soft, membranous area of ventral prosoma dark colored, rub marks present on opisthosoma indicating previous amplexus. |
|
In another trial, the shrew flipped the scorpion on its back and killed it quickly by puncturing the body wall at the junction of the prosoma and opisthosoma. |
