The egg cases of certain conchs look like leathery wafers strung on a cord. These strings of egg cases are called sea necklaces. Meat of the pink conch is used in chowder and salad. Crabs and Horseshoe Crab Crabs have ten legs. There are many kinds of crabs.
Some crabs live in burrows on the sandy shore.
Others live only in the water. The horseshoe crab, king crab, is more closely related to spiders than to crabs. The most common species are found on the eastern North American coast from Novia Scotia to Yucatan. Crabs wave their pincers in the air as a defense when they are disturbed. Shore crabs hide under rocks and seaweed at low tide.
