What is it?

The queen conch is a large sea snail with a magnificent spiral shell that can grow as big as a rugby ball. Its shell is famous for its beautiful pink, orange, and peach colours inside, and it is one of the most recognisable symbols of the Bahamas. Conch (say it 'conk') are so important to Bahamian life that locals sometimes call themselves 'Conchs'.

Inside the shell lives the conch animal itself — a soft-bodied creature a bit like a large snail. It uses a muscular foot to move slowly along the sandy sea floor and feeds on algae and sea grass. The conch breathes through a set of gills and can even right itself if it gets flipped over, using a powerful lunge with its foot.

Conch shells have been used by people in the Bahamas for thousands of years. Early inhabitants used them as tools, jewellery, and musical instruments — by blowing through the shell's tip, you can make a loud, resonant horn sound. Conch shell horns were used to call people together and even to communicate between islands.

The shell that most people recognise is actually the conch's outer skeleton, which it grows throughout its life. Young conch have thin, fragile shells; older ones have thick, strong shells with a flared lip. A full-grown queen conch has been building its shell for about five years. The pink colouring inside the shell comes from the animal's diet and the minerals in the surrounding seawater.

Queen conch are an important part of the Bahamian marine ecosystem. Their grazing keeps sea grass beds healthy, and their shells become homes for hermit crabs and other creatures after the conch has gone. The Bahamian government protects conch carefully so that they remain part of the reef for future generations.

Discussion prompts

  1. 01The conch is so important to Bahamians that people call themselves 'Conchs'. Can you think of an animal or plant that is so important to where you live that people might name themselves after it?
  2. 02Conch shells were used as horns to communicate between islands. What other clever ways have people found to communicate across distances in history?
  3. 03After a conch dies, its shell becomes a home for hermit crabs. Why is recycling homes in nature a good thing for ecosystems?
  4. 04If you picked up a queen conch shell, what do you think you might hear? Why does holding a shell to your ear seem to make a sound?

Classroom activity

Using a spiral template, design your own 'shell'. Decide what colour it is, how big it grows each year, what creature lives inside, and what other animals might use it later. Label your shell design with five facts about your imaginary species.
