| The cribellum is a cigar-shaped plate on the underside of the abdomen, in front of the spinnerets. |
| Six spinnerets with different types of spigots and a specialised spinning organ called the cribellum. |
| The last two abdominal segments are specially modified into spinnerets which secrete the silk threads for which spiders have become well known. |
| Their abdomens are variable in shape being triangular, round to ovoid to elongate, sometimes extending tail-like past the spinnerets. |
| The solution is then passed through a metal plate with fine holes, called spinnerets. |
| The cribellum is large for the size of the spiders and can generally be plainly seen just in front of the other spinnerets. |
