Is it okay for a dog to eat a hermit crab?

There are several dozen foods that are perfectly fine for humans but very bad for dogs/animals. Normal fish, If fed exclusively or in high amounts, can result in a thiamine (a B vitamin) deficiency leading to loss of appetite, seizures, and in severe cases, death. Lobster is a shell fish; not quite the same but it's better not to risk fido's life for a tasty treat. A tiny bit of anything now and then (even chocolate or grapes) won't kill them depending on the size of the animal but their food is based on their dietary needs for a reason.

Crabs and sharks are both aquatic animals, but they belong to different taxonomic groups. Crabs are crustaceans, while sharks are cartilaginous fish. Both have adapted to their marine environments with specialized body structures and behaviors, such as the crab's hard exoskeleton and the shark's streamlined body for swimming. Despite these differences, both animals play important roles in their respective ecosystems as predators.

What is the life cycle of a horseshoe crab?

The common species of crayfish (crawfish) live about 2 or 3 years, but individuals may live to be as old as 8 years. Some rare species can live as long as 20 years.

What are facts about hermit crabs?

here is a list of what you need to do to have a hermit crab as a pet:

1. when you go to buy a hermit crab look for one that is active

2. I suggest getting more than 1 (they will live longer with friends)

3. For 1 crab (or 2 small ones) you will need at least a 10 gallon fish tank. Those mini homes that they sell in stores are not good for your hermie. They need room to roam, play, and sleep.

4. The things that are needed in a hermit crab cage.

- a fresh water dish & a salt water dish (DO NOT use table salt it will kill him. You need to get it from the pet stores!)

-a food dish

-a coconut hut or other hiding house

-things for him to climb on

- sand (LOTS AND LOTS of sand)

-a humidifier (they need at least 70% humidity to survive)

5. Food. Commercial brand food is ok, but they need a variety. So, feed them: grapes, cantaloupe, sunflower seeds, and other human foods. (search the internet for other safe foods)

6. You HAVE to spray your hermie with fresh water at least once a day.

7. hermies don't eat much so dont worry when you dont see much of his food gone.

Hermit Crabs aren't as easy to take care of as it seems. If you have anymore questions i suggest asking you local pet store employees.

Hermit crabs are very social and LOVE company they usally don't live as long as they do when their with others. They can live over 2 years mine lived for 3 years.

Hermit DO FIGHT they fight over shells. one likes a shell the other has (make sure your hermies has alot of shells, NOT over crowding the tank!) and they fight. The victim usally dies over the fight.

But if you are there when it happens, you should blow on them if they still fight pick them up (do NOT pull them one will lose a limb!) if that doesn't happen you need to LIGHTLY mist them with distilled water.

Is the relationship between hermit crab and snail shell commensalism?

This would generally be viewed as a symbiotic or mutual relationship. The anemone benefits by being transported to different locations, some of which may be richer in food supply. The crab benefits from the camouflage the anemone provides, the partial protection of having a stinging anemone in close proximity and also from pieces of food which the anemone may drop.
