(ch1 and ch2), two pedipalps (p1 and p2), and four pairs of walking legs (l1-l4).
A drop of sperm is deposited on a thread held taut across his genital opening and from here it is picked up in his chelicerae
and absorbed by alternate applications of his palps.
Selden (1984) considered the possible function of pterygotid chelicera, concluding that the animals could rapidly extend these organs during hunting and that the curved tip and multiple denticles of the chelicerae
were effective in cutting up prey.
Brachytydeus formosa presents palps with 4 segments (trochanter, femur-genu, tibia, tarsus) (Figure 3), reduced fixed digits, movable serrated digits that are used to perforate food, and fused chelicerae
bases that were arranged one on top of the other.
Field cages were randomly assigned one of four treatments: 1) enclosures with only vegetation, where all herbivorous insects were actively excluded to serve as a control, 2) grasshoppers and vegetation, 3) vegetation, grasshoppers and spiders, and 4) vegetation, grasshoppers, and spiders with their chelicerae
glued with beeswax to prevent them from subduing prey and only acting as intimidating factors.
with 3 posterior teeth, close together, barely fused.
The jawlike chelicerae
rise 90 degrees and then slam fanged tips into the prey.
dark brown, endites dark brown with lighter tips.
The egg at the 35th hour of incubation showed the development of embryonic metameres which were anteriorely formed an acron, primary buds for pedipalp and chelicerae
and also first pair of legs.
In the city of Oriximina, northern Brasil (01[grados]45'S, 55[grados]50'W), two males were observed on tree trunks near the water, each holding in the chelicerae
a small, wrapped prey, consisting of an immature Ctenidae spider for one of them and an immature Lycosidae spider for another one (Figs.
Instead they have fang-tipped jaws called chelicerae
that are used to inject digestive enzymes into prey.
Then, the spider ingests the partially digested food by smashing it to a pulp with its chelicerae
, or a fang and a base, each of which may have teethlike projections.
, or mouth parts, rip the food to pieces, turning it to pulp while the digestive system secretes enzymes that liquefy the unrecognizable mass.
Spider jaws are called chelicerae
, and include hollow fangs through which they inject venom to immobilize or kill their prey.
Sunlight illuminates her body, accentuating the furry body hairs, the minute chelicerae
forking in front of her mouth, ending in hollow fangs.
