Are you afraid of shellfish? Are the mere sight or smell of seafood enough to make your skin crawl and your heart race? If, you may be suffering from ostraconophobia.

Ostraconophobia is an irrational fear of shellfish, which includes crabs, lobsters, prawns and other crustaceans. It can manifest itself in a variety of ways – from mild discomfort or aversion at the thought of eating seafood to extreme anxiety when confronted with any type of shellfish. In severe cases, it can even lead to full-blown panic attacks.

Although this phobia isn’t talked about much in mainstream media or popular culture, there are millions who suffer from it all over the world. In this blog post we will explore what causes ostraconophobia and discuss how people can cope with their fears and reclaim their lives back from its grip.

What is Ostraconophobia?

Have you ever heard of ostraconophobia? It’s a phobia that affects some people and makes them intensely afraid of shellfish. Yes, you read that right- shellfish! From shrimp and crabs to oysters and clams, these creatures can cause extreme anxiety and panic in those with ostraconophobia. 

The word ostraconophobia comes from the Greek words “ostrakon” meaning shell and “phobos” meaning fear, so it is literally the fear of shells.

This phobia is considered a type of specific phobia, which means it is an excessive or irrational fear of a particular object or situation. Many people with ostraconophobia report feeling extremely uneasy around shellfish, even if the shellfish is not directly threatening them in any way. 

Interestingly, ostraconophobia is not a very common phobia and little research has been done on it specifically. However, it is speculated that it may be related to other phobias such as apiphobia (fear of bees) or cynophobia (fear of dogs), which are also specific phobias related to certain animals. Some experts believe that the fear of shellfish may come from a traumatic experience, negative upbringing, or simply through observing others around them. 

When it comes to types of shellfish, ostraconophobia can encompass a variety of creatures. Common examples include mussels, scallops, lobster, and even barnacles. It’s important to keep in mind that people with ostraconophobia may have different triggers and levels of severity, so what may not seem like a threat to one person may cause intense fear in another.

Causes of Ostraconophobia

So, what causes ostraconophobia? There are several factors that can contribute to the development of this condition. Here are some of the most common ones:

Negative Experience

One of the most typical causes of ostraconophobia is a negative experience related to eating shellfish. This could be anything from getting sick after consuming shellfish to having an allergic reaction.

For example, if someone ate shellfish and later experienced vomiting or other unpleasant symptoms, they may develop a strong association between shellfish and physical discomfort. This association can then trigger intense anxiety when encountering shellfish in the future.

Cultural Influence

Cultural influence is another crucial factor that contributes to the development of ostraconophobia. In some cultures, shellfish are considered taboo or even forbidden. For example, in Judaism and Islam, certain types of shellfish are prohibited. Growing up in a culture or religion that demonizes shellfish can lead to ostraconophobia, even in the absence of any negative personal experience.


Recent research has also suggested that genetics can play a role in ostraconophobia. According to the study, certain genetic factors can increase the likelihood of developing shellfish allergy and may even contribute to the development of shellfish phobias. While more research needs to be done in this area, the findings are promising in terms of developing more effective treatments for ostraconophobia.

Symptoms of Ostraconophobia

If you’re one of the unlucky people who suffer from ostraconophobia, the fear of shellfish, you know just how debilitating it can be. Just the thought of coming into contact with a shellfish can send shivers down your spine and cause a full-blown panic attack.

But what are the specific symptoms of ostraconophobia that make it such a distressing condition to live with? Let’s take a closer look.

Physical Symptoms 

One of the most common symptoms experienced by those with ostraconophobia is physical in nature. This can include sweating, shaking, and shivering, which are all signs of the “fight or flight” response that kicks in when the brain perceives a threat.

Nausea and vomiting are also common, as well as elevated heart rate and difficulty breathing. These symptoms can occur even if you’re only imagining a shellfish, making it difficult to go about your daily life without constant fear.

Psychological Symptoms 

The psychological symptoms of ostraconophobia can be just as distressing as the physical ones. Sufferers can experience intense feelings of terror, panic, disgust, and overwhelming dread at the mere thought of shellfish.

They may also experience intrusive thoughts, which can lead to obsessive-compulsive behaviors such as avoiding any location where shellfish might be present. Along with this, many people with ostraconophobia also struggle with anxiety, depression, and other mental health issues.

Some people with ostraconophobia even decide to avoid going to the beach altogether, convinced that they’ll come into contact with shellfish in the water or on the sand.

Medication: In some cases, medication may be prescribed to help manage symptoms of ostraconophobia. Anti-anxiety medications, beta-blockers, and antidepressants are all commonly used to treat phobias.

Hypnotherapy: This alternative therapy involves inducing a state of deep relaxation, in which the patient can access their subconscious mind. It can be helpful for uncovering the root cause of your phobia, and reprogramming your thought patterns.
