Oysters are some of the most fascinating creatures in the natural world. They’re not only delicious to eat, but also play a huge role in coastal ecosystems. Here we look at some amazing oyster facts.

In an effort to provide us with a million oysters a year, the UK’s first oyster restoration hatchery has just launched at Langstone Harbour, Hampshire. Once thriving, oysters have become almost extinct in the Solent and many other areas of Europe, having declined by more than 90% since the 1800s. The project is designed to help rejuvenate an industry that fell into decline nearly a decade ago.

Amazing oyster facts

If you want to be a connoisseur not just in taste, but in knowledge too, read on…

1. Oyster reefs are in danger

Oysters are free-floating creatures that attach themselves to rocks, piers and other hard surfaces, where they form vast reefs. These reefs help create the right conditions for hundreds of other marine species to thrive, as they’re an important source of food, naturally filter water and even act as storm protection.

Wild oyster populations are in danger of becoming extinct though; pollution, overfishing and climate change are all having a devastating effect on numbers.

2. Oysters can change gender

All oysters start life as males and usually end up as females in their later years, as this helps them keep populations high. Their reproductive organs produce both sperm and eggs, and they can change gender several times over the course of their life.

3. Some people consider them vegan

Oysters and scallops are part of the bivalve family, so while they are living creatures, they don’t have a central nervous system – which means they don’t feel pain (although some argue research is lacking on this point).

Some vegans are happy to eat them, although others say that because oysters close their shells when under threat, they may have the ability to feel fear.

4. They have a three-chambered heart

Oysters have a three-chambered heart that pumps colourless blood around their fleshy form. Like fish, they also breathe through the use of gills. Wild oysters can live for a whopping 25 to 30 years, but many don’t survive that long.

5. An oyster can filter 50 gallons of seawater a day

Oysters and other shellfish act as natural filters for the sea. They help remove excess nitrogen and other pollutants from the water by consuming them. In fact, adult oysters can reportedly filter up to 50 gallons of seawater a day.

6. Pearls don’t actually come from edible oysters

These days, the pearls used in jewellery are cultured (humans intervene and create the right conditions). When naturally occurring, pearls are created as a natural defence against an invading parasite or other threat, which could cause damage to the oyster’s body. But the species we tend to eat don’t operate in this way.
