After those first few days, a horseshoe crab will spend the majority of its life on the sea floor.

How long does it take horseshoe crab eggs to hatch?

14 to 30 days
Horseshoe crab eggs typically hatch 14 to 30 days after fertilization (Sekiguchi, et al., 1982; Jegla and Costlow, 1982; Botton, 1995), but factors such as overcrowding or high-density egg clusters can prolong the incubation period (Barber and Itzkowitz, 1982).
