Fiddler crabs have clear scales over their eyes, but they do not have eye lids that move like we do.

yes they will but certain tipes of fruit though.

its probably dying or sick

Hermit crabs are considered to be in the arthropods family. Hermit crabs have a hard exoskeleton made of chiton which helps provide protection and give the muscles attachment support. Although a hermit crab will grow, their exoskeleton does not so they must constantly shed said exoskeleton in favor for a new one that it grows into.

There are a huge number of differences between a crab and a fish including the fact that most fish do not have a hard shell or carapace while most crabs do have this type of covering. Crabs also have legs and claws while fish do not have those appendages.

Check if it is moving because it is most likely dead. If it is dead it will smell like dead fish Or check its food. It might be making the smell.

Yes they do. Spiders are the favorite food of crabs.

a crab can live forever until something eats it or squishes it

yes

No. If it's small enough for the Goldfish to try and eat it, it will. If it's a larger type of crab, like Fiddler or Rainbow, then these need salty water and land to get out on and will try and catch and eat a Goldfish.

Yes. They capture water in their gills.

Typically its about to molt or in the process of shedding it's outer shell, molting.

A well taken care of crab can live 30-50 years.

3-5 days if refrigerated shortly after cooking

it is a vetabrate if it has a endo skeleton made of bone or cartilage

A ghost crab isn't a single type of crab, but is a group or related crabs of the species Ocypode. They have a bit of range in their sizes, as you might guess, but the largest ones run just a few ounces, tops. A link is provided below.

Well, I know some because I have one, and for one, the 'Answer' was a question. See other 'posts' to mantain the balance of the society, of lower-numbered questions.

Shallow water is more dense than Deep water. This means that a wave travelling from deep water to shallow water would bend towards the normal. Also, the wave would travel slower in the shallow than in the deep water

Jellyfish have no skeletons so they don't need to worry about it.

it usually poops when it has grown more. so every time it poops you know its growing

Congratulations! No need to rename it. It's the same hermit crab. It molted it's old skin! This means your hermit crab is perfectly healthy and can grow! Make sure you have a slightly bigger shell though. Leave it alone until it walks around and is very healthy.

No they do not kill each other becaues they love each other

There are three possible answers here depending on the kind of crab.

1. If you purchased them at a boardwalk store then bring them home and follow the care guidelines outlined on www.crabstreetjournal.com

2. If you took land hermit crabs off the beach you can care for them much the same way but please know that personally harvesting land hermit crabs is illegal without a permit.

3. If you accidentally took marine hermit crabs out of the tide pools they need a very careful slat water setup, complete with live rock or else they will die.
