help Desis martensi FAQ
What kind of habitat does the Desis martensi spider live in?
Unlike most spiders, Desis martensi is a marine species that lives in the intertidal zones of coral reefs across the Indo-Pacific. It is uniquely adapted to survive in harsh, saltwater environments.
How does the reef spider breathe underwater?
The spider does not have gills; instead, it spins air-filled silk retreats within the crevices and holes of coral reefs. These webs act as physical diving bells, trapping surface air that the spider uses to breathe during high tide.
What does the Desis martensi spider eat?
Because it hunts in the intertidal zone, its diet consists primarily of small marine arthropods and crustaceans. It actively hunts these creatures during low tide when the reef is exposed or in shallow tidal pools.
Are Desis martensi spiders dangerous to humans?
While all spiders possess venom to subdue their prey, Desis martensi is very small and its venom is not considered dangerous to humans. They are quite elusive and prefer to hide in their coral retreats rather than interact with people.
