  Identifying features are:

1. Multicellular heterotroph.
2. embryonic development, preceded by heterogametic fertilization.

            Hence, the specimen belongs to the Kingdom Animalia.

1. Segmented body covered by chitinous cuticle.
2. Body segment bear paired externally jointed appendages.

1. Elongated, cylindrical or subcylindrical body.
2. Body is composed of many diplosegments, each with two pairs of legs.
3. Legless first body segment.
4. Gnathochilarium & mandibles are included in the mouthparts.

               Hence, the specimen belongs to the Class Diplopoda.

1. Antenna seven segmented.
2. segments are cylindrical or flattened.
3. Body sclerites are fused to form rigid ring.
4. Seventh segment bears two pairs of gonopods.

                   Hence, the specimen seems to be Julus sp.
