In honor of the spooky season, the Lake Superior Zoo is showing off some of their creepier and crawlier residents: Madagascar Hissing Cockroaches and African Giant Millipedes.

Both are detritivores, meaning they eat dead and decay material and break it down back into the earth.

These cockroaches can get up to 3 inches long, making them one of the largest kinds in the world.

Cockroaches has poor eyesight and rely heavily on there antennas.

Millipedes are not insects because they have more than six legs. When fully grown, they’ll have 300-400 legs on average.
