These allergies tend to develop later in life than the common childhood allergies. Allergies to crustaceans and molluscs are usually lifelong. People who are allergic to one type of seafood, may not be allergic to other kinds of seafood. Many people are only allergic to a single type of seafood. For example, some people can eat fish safely, but have allergic reactions to crustaceans like lobster or crab.
If you are allergic to one type of shellfish like molluscs , consult your allergist before trying other types like crustaceans.

Crustacean and molluscs should be listed on the label of pre-packaged foods using their common names e. The "may contain" label might contain the specific type of crustacean or mollusc e.
They live in inland and ocean waters from the Arctic to the Antarctic as well as from elevations in the Himalayas up to 16, feet to well below sea level. Crustaceans include commonly-known marine life such as crabs, lobsters , barnacles, and shrimp.
These animals are in the Phylum Arthropoda the same phylum as insects and Subphylum Crustacea. The largest crustacean is the Japanese spider crab, at over 12 feet long; the smallest are microscopic in size. All crustaceans have a hard exoskeleton which protects the animal from predators and prevents water loss. However, exoskeletons don't grow as the animal inside them grows, so crustaceans are forced to molt as they grow larger.
The molting process takes between a few minutes to several hours. During molting, a soft exoskeleton forms underneath the old one and the old exoskeleton is shed. Since the new exoskeleton is soft, this is a vulnerable time for the crustacean until the new exoskeleton hardens. After molting, crustaceans typically expand their bodies almost immediately, increasing by 40 percent to 80 percent.
Many crustaceans, such as the American lobster , have a distinct head, a thorax, and an abdomen. However, these body parts aren't distinct in some crustaceans, such as the barnacle. Crustaceans have gills for breathing.
Crustaceans have two pairs of antennae. They have mouths made up of one pair of mandibles which are eating appendages behind the crustacean's antennae and two pairs of maxillae the mouth parts located after the mandibles. Most crustaceans are free-ranging, like lobsters and crabs, and some even migrate long distances.
But some, like barnacles, are sessile —they live attached to a hard substrate most of their lives. Crustaceans are a subphylum of the Arthropoda phylum in the Animalia. If you're looking for crustaceans to eat, look no further than your local grocery store or fish market. But seeing them in the wild is almost as easy.
They are also known as cobra, a name from the local Aboriginal name, cah-bro. They are a marine wood-borer which inhabit trees and logs that have fallen into the water and remain submerged, preferably in still water. The only crustaceans reported by the colonists to have been eaten were crayfish, which were caught in Port Jackson with small hoop nets. There is no mention at all of prawns, crabs or barnacles being caught or eaten, though the name for crabs, Ke-ra , was recorded. Archaeological excavations have recovered only small amounts of crab and crayfish remains.
The fragility of the exoskeletons, which do not survive well in archaeological deposits, probably explains why only small amounts are found. Barnacles occur in middens, but they may not have been collected for food as they often attached themselves to other shellfish that were eaten.
