whelk egg capsules are coin-shaped, 20 to 30 mm (0.8 to 1.2 inches) in diameter and 3 to 6 mm (0.1 to 0.2 inches) thick with crenulations around the edges. Eggs develop slowly, hatching in about 3 to 13 months. Usually egg cases found washed up on beaches are empty with open holes that provide evidence of successful hatches.

Common Name: Whelk Egg Casing Scientific Name: Busycon species Fun Facts: Whelk eggs are laid in intrinsically spiraled strings of egg capsules that resemble the cord of an old-fashioned hair dryer. Each capsule houses 100-200 eggs that go through several stages before developing into tiny whelks within the egg It lays its eggs in a spongy mass of up to 2000 egg capsules on the seabed. Once hatched, these balls of empty egg capsules often wash up on shore. The common whelk is carnivorous and feeds on worms and other molluscs, often using the edge of its own shell to prize open other shells.

The pear whelk is a medium-sized shell and is not as common as the other snails we often see in this area. This smooth shell lacks horns like the lightning whelk and is not as colorful. These snails also lay long snake-like chains of egg capsules that are very similar to the lightning whelk.

Whelks reproduce by sexual reproduction with internal fertilization. Some, like the channeled and knobbed whelks, produce a string of egg capsules that maybe 2-3 feet long, and each capsule has 20-100 eggs inside which hatch into miniature whelks. Waved whelks produce a mass of egg capsules which look like a pile of egg cases.

Common names: 'northern whelk', 'edible whelk', and 'European whelk' It is the largest sea snail found in our seas and therefore the largest snail shell you are likely to find on our beaches. It lays its eggs in a spongy mass of up to 2000 egg capsules on the seabed. Once hatched, these balls of empty egg capsules often wash up on shore. The common whelk is carnivorous and feeds on worms and other molluscs, often using the edge of its own shell to prize open other shells.
