If it doesn't kill 'em, it'll give 'em one heck of a good time, partying it up with the squid and starfish as the tide rolls in- who's up for sandshots!, anyone?
Seriously though,
the only studies I have read regarding alcohol and crustaceans have to do with Daphnia- a tiny microscopic crustacean used in many lab experiments- Results: when ethanol (alcohol) was administered to the Daphnia in large doses- it killed them.
Whether this means that you have to immerse a crab in a tank of alcohol or absorb its food in alcohol before the crab consumes it- I am unsure. But, both are cruel and would be considered a form of animal abuse.
Don't forget- Alcohol is a drug. A drug, by definition is a substance that effects the natural biochemistry of the body- this includes a little crustacean body!
What is the best type of cage for a hermit crab?
Fish tank with a screen top. You will also need a reptile light, water dish, and other accessories. If you go to your local mom and pops petstore, petco, petsmart or some place like that they will help you pick out everything you need for the fish tank
How do female insects deposit their eggs?
Female insects deposit eggs in a different ways depending on the species of insect. Some insects lay eggs on the ground, some lay eggs in the water and on leaves, and some female insects bury their eggs.
How do you tell a marine hermit crab is a boy or a girl?
If you look at the underside of your crab, on it's last pair of walking legs under it's abdomen, a female will have a dot on each side, these dots are called gonopores. They are what determines whether or not you have a female or a male crab
Because arachnids and crustaceans share a pair of appendages called chelicerae, which are specialized mouthparts that we find in both arachnids (spiders) and horseshoe crabs. In fact, these mouth parts define the name of the entire subphylum to which these animals both belong, the Chelicerata. There are a few different types of chelicerae, but in arachnids, these would be the mouth parts that most people think of as 'fangs,' some which are of course venomous. In horseshoe crabs, they are the anterior-most (front-most) pair of appendages, look like small claws, and are used for feeding.
YES! The Hawaiian strawberry crab, red boxing crab, or strawberry crab (Neoliomera pubescens) is a small, bright pink crab that has small white bumps on the main shell and whitish claws. It is found in the Indo-Pacific region, including Hawaii, Mauritius, and French Polynesia.
Yes
F. leucobalia have developed the method of "'loop-and-pull" behavior. The snakes are seen wrapping their bodies around a hard shelled crab, holding it in place, and then biting off the legs. If the crab body is not too large it will also be consumed.
Can hermit crabs have no iodine sea salt?
No. Crabs need ocean style salt water mixed with products you buy at the pet store. Table salt contains an anti-caking agent which can be harmful. Table salt also lacks the trace metals and minerals that are in the water mix that hermit crabs need.
Meaning of the quotation Big sisters are the crab grass in the lawn of life?
This quotation uses a metaphor to suggest that big sisters can be seen as invasive or unwanted elements in one's life, similar to how crab grass is an undesirable weed in a lawn. It implies that big sisters can be seen as bothersome or overbearing, disrupting the smoothness and beauty of one's life. The comparison highlights the idea that big sisters may sometimes be seen as a nuisance or source of annoyance rather than a positive influence.
Will crab spiders eat silk worms?
This would be a great thing to test and I'm pretty sure they do. Its funny cause in spring I did indeed test this, wondering the same question. As proof, i took the silkworm victim, placed him on the web, and there went the spider. I checked every twenty minutes and the spider was sitting right next to it as what seemed to have been "Dinner".
An international team of scientists recently announced the discovery of a new species of blind deep-sea crab whose legs are covered with long, pale yellow hairs. This crab was first observed in March 2005 by marine biologists using the research submarine Alvin to explore hydrothermal vents along the Pacific-Antarctic ridge, south of Easter Island. Because of its hairy legs, this animal was nicknamed the "Yeti crab," after the fabled Yeti, the abominable snowman of the Himalayas.This drawing shows the Yeti crab that was collected by scientists on the Pacific-Antarctic ridge. The drawing was created by scientific illustrator Karen Jacobson, who worked with the scientists on board the research ship Atlantis.

The Yeti crab was discovered during the Easter Microplate expedition to the southeast Pacific, led by MBARI scientist Bob Vrijenhoek. The primary goal of this expedition was to learn how bottom-dwelling animals from one deep-sea hydrothermal vent are able to colonize other hydrothermal vents hundreds or thousands of miles away. Vrijenhoek and his team were addressing this question by comparing the DNA of animals at hydrothermal vents in different parts of the Pacific Ocean.
During one Alvin dive, marine biologist Michel Segonzac, from Institut français de recherche pour l'exploitation de la mer (IFREMER) in France, noticed an unusually large (15-cm-long) crab with hairy arms lurking on the seafloor. Segonzac asked the Alvin pilots to collect this crab and bring it back to the surface.
The researchers saw more of these unusual crabs during subsequent Alvin dives. Most of the crabs were living at depths of about 2,200 meters (7,200 feet) on recent lava flows and areas where warm water was seeping out of the sea floor. According MBARI biologist Joe Jones, "Many of the crabs were hiding underneath or behind rocks---all we could see were the tips of their arms sticking out."
After returning to shore, researchers Segonzac and Jones worked with Enrique Macpherson from the Consejo Superior de Investigaciones CientÃficas (CSIC) in Spain to identify the crab they had collected. They found that the crab was not only a new species (which they named Kiwa hirsuta), but an entirely new family (Kiwaidae). The Yeti crab is a distant relative to the hermit crabs commonly seen lurking in tide pools.This map shows the locations of hydrothermal vents along the Pacific-Antarctic ridge that scientists explored during the Easter Microplate expedition. The vent sites are indicated by black dots with labels indicating their latitudes.

I love that question! I got my hermies from petsmart too.(hermies can live for over 6 yrs in captivity)
Hermies need the right temp (70-80) and humidity (70-85%) or they will die. They also need friend because they are very social, 2-4 hermis in a ten gallon tank (i used fish tank at petsmart cause it was way cheaper and came with a lid),
hermies also need sea salt water because they need to have that to harden their exoskeleon, (SEA salt because table salt will burn their modified gills and will kill them), and distilled water because clorine in tap water will burn their modified gills and will sofacate them.
Hermit crabs also need coconut fiber dirt and sand(optional). I have recently mixed sand with the dirt and my hermies LOVE it. they love to burrow so have the dirt deeper than your biggest hermies (they still try to dig down deeper).

Are crabs supposed to eat their water sponges?
no, a land hermit crab is not supposed to eat the sponge unless they are in bad condition
Is it normal for crabs to produce bubbles?
Aquatic crabs held above the water will produce bubbles through respiration. They draw the air into the space between their claws and shell (arm pit area essentially) and blow it out through their mouth. The protein in the water keeps the bubbles formed from bursting quickly, thus they "blow bubbles".
Can you have an allergic reaction after eating blue crabs?
You certainly can. Besides peanuts, allergies to shellfish are one of the most common food allergies (by shellfish I refer to both mollusk (oysters and clams, etc.) and to arthropods (lobster, shrimp, crab). The allergy can range from mild -- rashes and hives -- all the way up to anaphylactic shock and, in rare cases, death. You can verify this with your doctor. Depending on how strong the allergic reaction is, for extreme cases, getting this tested and verified is a good idea, as they can prescribe "allergy kits" that, in an emergency, can save your life. Or you can be very careful not to eat these animals again. Unlike peanuts, they aren't used in a lot of foods without saying so. Note that if you're allergic to blue crabs, that may mean the allergy extends to all forms of crab, shrimp, lobster, crawdads and crawfish, langostino, etc.
Where do you place the food when you feed the hermit crabs?
You place it anywhere that is easy to reach, the hermit crabs will small the food.
They are mostly nocturnal so they will be more active at night and will eat more.
