It is a Cave orb-weaver spider (tentative).

Scientific name: Meta sp. (tentative).

A brown, long-legged spider with a relatively small cephalothorax and a larger, rounded to egg-shaped abdomen. The abdomen appears dark gray-brown with lighter patches, although its markings are blurred. Eight jointed legs spread around the body; they are tan to brown with darker bands, particularly near the joints. Shorter mouth-associated appendages cluster at the front. The spider is positioned against a rough rock surface, with a few fine silk strands visible nearby. The photograph appears to show an oblique underside view..

Cave orb-weavers often live near cave entrances rather than in the deepest passages, placing their webs where insects move between the surface and the underground environment..

The two-part body, eight long legs, rounded abdomen, and nearby silk identify this as a spider. Its dark body, distinctly banded brown legs, and position beside rock are consistent with cave orb-weavers in the genus Meta. However, the image is soft-focused and does not clearly show the dorsal abdominal pattern, eye arrangement, or other diagnostic features. Other web-building spiders, including cave cobweb spiders, can look similar, so the genus identification is provisional and a species cannot be determined reliably.
