What Is the Orange Stuff in a Female Crab?

So you either caught or purchased a crab and you’re noticing it has orange stuff along the underside of its shell?

Don’t be startled the crab isn’t sick or infected, It’s simply a female crab, and those tiny orange bubbles on its underside are eggs, or “roe”.

These tiny, edible little eggs, each represent crab larvae, and potentially a future baby crab!

Located around the carapace of the female crab they can be identified by their bright orange colour and round mass shape. The eggs can be eaten raw or warmed and are rich in omega-3’s.

Many people will describe the flavour as somewhat sweet and salty and will complement it with toast and the like.



Sponge & Crab Roe Explained

As a  female crab matures and mates they will grow a “sponge” and produce a mass of eggs. This mass of eggs will develop on the rear of the female crab on her underbelly and will appear as bright orange bubbles.

These orange bubbles, or eggs, are ripe internal egg masses of crab larvae. The crab will generally take from 2-9 to release the eggs after mating.

This “sponge” or mass of eggs will be attached to the crab via fine hairs, around the crab’s apron/ abdomen area and contain up to 8 million eggs, with most female crab averaging 2 million to 2.5 million eggs.

Most eggs will not survive to maturity as a male or female crab.

It should also be noted, as the female crab nears the release of the eggs they will gradually change colour from their initial bright orange to a darker more brownish shade.
