![]() ![]() Golden king crabs live much deeper, from 200-500 m, so they may not be exposed to strong seasonal signals. It lacks functional mouthparts or digestive apparatus so does not feed for 3 to 4 weeks, until molting to the juvenile stage. It can swim like the larvae, but has claws, and prefers to find structurally complex habitat in which to settle. The glaucothoe is a transitional stage between the larval and juvenile stages of king crabs. However, most seamounts in the Gulf of Alaska are too deep for red king crabs. As a result, they all reproduce during a specific season in the spring. Because of this they are exposed to seasonally changing conditions of temperature and day length. Red king crabs live in relatively shallow water (less than 50 m). Red king crabs do this too, but before they become bottom-dwelling crabs, they go through a transitional stage that is not capable of eating. Most crabs hatch from eggs as a swimming shrimp-like larva, that immediately begins to feed on small planktonic organisms. King crabs also have an unusual mode of development. Thus they can walk straight forward, unlike a Dungeness crab that normally walks sideways. Their abdomens (or tail-section) are twisted to one side, they have large right-handed claws, and their legs fold backwards, instead of forwards. They are closely related to hermit crabs, and have many similar characteristics. What are some of these, and what advantages do they offer?įirst of all, king crabs are not typical crabs. Most have evolved specific adaptations to cope with life in deep water. But as you go deeper into the sea, the crabs you encounter become ever more strange. Most of what we know about crabs comes from studies on shallow water species, such as the red king crab (the kind we normally eat).

Machine wash and dry clothing worn and bedding used by the infested person in the hot water (at least 130☏) laundry cycle and the high heat drying cycle.If you have an STD, don't have sex (oral, vaginal, or anal) until all partners have been treated.Have regular check-ups if you are sexually active.Careful consideration and open communication between partners may protect all partners involved from infection. Use latex condoms for all types of sexual penetration (oral, vaginal, anal). Note: Latex condoms, when used consistently and correctly, can reduce the risk of transmission of other STDs, but are not considered effective against crabs.Limit the number of sex partners to reduce your risk of all STDs.Mutual monogamy (having sex with only one uninfected partner).Persons with pubic lice should be evaluated for other sexually transmitted diseases.Repeat treatment in nine to ten days if live lice are still found.Persons should avoid sexual contact with their sex partner(s) until both they and their partners have been successfully treated and re-evaluated to rule out persistent infestation.All sex partners from within the previous month should be informed that they are at risk for infestation and should be treated.Items that cannot be laundered can be dry-cleaned or stored in a sealed plastic bag for two weeks.Use hot water (at least 130 degrees F) and the hot dryer cycle. To kill any lice or nits remaining on clothing, towels or bedding, machine wash and machine dry those items that the infested person used during the two to three days before treatment.Put on clean underwear and clothing after treatment. ![]() Nits may be removed with fingernails or by using a fine-toothed comb. Following treatment, most nits will still be attached to hair shafts.After waiting the recommended time, remove the medication by following carefully the instructions on the label or in the box. Leave medication on hair for the time recommended in the instructions. Thoroughly saturate the pubic hair and other infested areas with lice medication. Carefully follow the instructions in the package or on the label. ![]()
