The young copy their parents
Sand hoppers were reared indoors and during
their growth had never seen the sea or sky. These sand hoppers when placed
on a beach with the sea in the same direction as where their parents originated
from, were able to navigate in the right direction, whereas sand hoppers
that were placed on the "wrong" beach wandered off in the wrong direction.
Stay in their hole with the young
Sand hoppers can be as old as 1,5 years.
The female mates first after she has sheded her exoskeleton for the last
time. She can then have up 34 eggs in her nursery a couple of times during
the same summer. She stays in her hole the whole time she has eggs or
young.
Sufficiently warm and dry during the
winter
Hibernation during the winter can be as
far down as 50 cm in the sand or seaweed at a safe distance from the high-water
level. Those sand hoppers that hibernate in seaweed usually have it
very comfortable because of the heat that is generated from the rotting
seaweed.
