Tony Geiger tells sisters, Sarah and Chloe Lockwood, of Kennett Square, Pa. how sea stars like this one can live under rocks - just like SpongeBob’s friend Patrick does.
During one of the institute’s free aquarium feeding sessions held at the Diller Coastal Education Building, Geiger scooped up a horseshoe crab from a bucket of creatures.
At first glance, the prehistoric creatures look like giant sea roaches with menacing swords slashing out from beneath their greenish-brown shells.
“They are weird looking,” Geiger said to the small group of children who cringe at the creature’s odd appearance, “but they are actually very friendly.”
