Crabs has protein. In every 100g of blue crab (canned, raw, or cooked), it has 18g protein. Highest protein number is with queen crab (cooked) with 24g protein per 100g.
yes
Yes. All crabs have blue blood, not just the species known as the blue crab. The reason for the blue blood is that crabs do not have haemoglobin, which is found in the blood of vertebrates, and which is red due to the iron molecule in the centre of the protein. Instead, crabs have a protein called hemocyanin, which contains a copper molecule. This is particularly pronounced in the horseshoe crab, the blood of which is a stronger blue than other species.
White glue is protein based, and is perfectly harmless for crabs to eat.
Yes, I've had this problem too. Lots of lotion and massaging worked well for me. My crabs loved to eat semen, it's very healthy and full of protein.
If you mean land hermit crabs, no, they don't. Hermit crabs of all sizes can get along just find as long as you: 1. Have enough room. Think of it as 3-5 gallons per crab needed. 2. Are feeding them protein and calcium along with fresh fruits and veggies.
No. They just miss out on the extra protein they would have gotten.
