Do You Know These Holiday Crabs?

Like the friends and family that you’ll be spending time with during the holidays, crabs exhibit all kinds of shape, sizes, and behaviors. If you’re going to be a crab for the holidays, be one of these.

1. Coconut Crab

The coconut crab is the largest terrestrial invertebrate in the world. They can have a leg span of up to 3 feet! They also live up to 120 years old. Can you guess one of their favorite foods? Coconuts! Though they are said to eat everything…

During the Holidays: Enjoys tropical destinations and beaches during the holidays. Will often eat what they want, just because.

2. Purple Shore Crab

Found all along the West coast, these crabs live in the shallow tide pools like those found on Oregon Coastal Refuges Complex . They hide under rocks to try to avoid being eaten by fish, gulls, and other birds. They like to feast on green algae, snail eggs, and crustaceans. They are about two inches in size.

During the Holidays: Participates in holiday festivities in a reasonable way. They are enthused enough but are not going to make a fuss.

3. Blue Land Crab

The blue land crab is mostly a vegetarian burrowing crab that stays close to home. They don’t usually wander beyond 100m to find their food. They are most active at dawn and dusk.

During the Holidays: Always dressed to impress — this is one classy crab to invite to your parties. They won’t be out much after dusk, but they’ll make an impression while they’re there.

4. Hermit Crab

There are nearly 1100 species of hermit crab, and they range in size and shape- but most of them rely on a scavenged shell to conceal their abdomen. They can live anywhere from 12–70 years!

During the Holidays: They may be somewhat reserved, but you can usually get them to come part way out of their shell during the holidays. Just ask them lots of questions.

5. Ghost Crab

Ghost crabs get their name from their “ghostly” color which allows them to camouflage with their sandy environment. They are nocturnal and are most active at night. They’ll dig J-shaped burrows usually with a way to exit nearby.

During the Holidays: They may or may not show up to events, and even if they seem like they’re having a great time, they may not call or respond. Tips for engaging? Have your events at night and always allow them an exit.
