Population
Locally this species is very common and abundant.
Current Population Trend: Stable
Habitat and Ecology (see Appendix for additional information)
E. limulus is a benthopelagic (ecological region at the lowest level of water body) species, that was found
inhabiting a small river with moderate water currents, a bottom of mostly rocks and is not found in
areas with sandy bottoms.
Systems: Freshwater
Threats
No threats to this species. Whilst there is damming in the area this species is only found in the smaller
tributaries and therefore not threatened by this disruption. There could possibly be a minor threat of
pollution in the area.
Conservation Actions
There are no conservation measures in place.
