Marine Jumper
Although this species lacks the vivid colours displayed by many jumping spiders, it is readily recognised as the only jumpers known to live exclusively in the intertidal zone along Singapore’s coastline and that of its outlying islands. Both sexes are dully coloured, but the male has a thicker mane of white hairs on the clypeus and more distinct spots on the abdomen than that of the female.
Newly hatched spiderling
An underwater chamber exposed during low tide. It is made of sealing valves of oyster shells with thick silk. Spiderlings were hatched within the underwater nursery.
| Length | ♀ 7 mm; ♂ 5 mm |
| Type Locality | Port Dickson, Negeri Sembilan, Malaysia |
| Distribution | Singapore, Malaysia (Negeri Sembilan). |
| Habitat | Among rocks, coral rubble and oyster and barnacle beds. |
| Biology | The spider can sit, run and even hop on the water surface. It forages for marine creatures during low tide and hides in an underwater chamber sealed by thick silk during high tide. The chamber may be built between rock crevices, within dead barnacle shells, or between the valves of dead oysters. Eggs are laid within the chamber and serve as an underwater nursery before the spiderlings disperse. |
