Abstract: Intraspecific aggressive burrow defense beha vior of the sea
urchin Strongylocentrotus purpuratus was observed. An urchin occupying a
burrow defends its position against intruders by moving out from the burrow
and pushing the intruder away. Only spines are used in this behavior. When the
intruder begins to retreat, usually within minutes, the occupant returns to the
burrow. The burrow defense behavior of S. purpuratus was compared to that of
the tropical urchin Echinometra lucunter.
