The brown shrimp, Penaeus aztecus, is a species of grooved, burrowing shrimp, common in Florida waters. Antennae are significantly longer than body length. Its carapace has a medial carina on the anterior surface that is bordered on either side by a broad, somewhat rounded groove. The prominent rostrum is slightly upturned with 5-10 sharp teeth on the upper edge. The integument is thin and translucent in appearance. Chromatophores give the animal a brown to olive-green appearance, though both red and green specimens of this species have been reported. The first 3 pairs of walking legs are chelate. Uropods are rounded and generally colored reddish-brown in the distal portions. The telson bears a sharp tip and a deep medial groove anteriorally. \nThis species exhibits sexual dimorphism, with females growing larger than males. Generally, males attain only 3/5 of female weight, and 5/6 of female length. Females are further distinguished by the presence of a closed thelycum located on the ventral sternum of the thorax, while males are identified by the presence of the pentasma.

SOme are real lobsters and some are crayfish.  To tell if it is a genuine lobster look at the claws.  Lobsters have two different size claws where crayfish do not.\n\nBlue Lobsters - Fact or Fiction?\nBlue Lobsters Are Real! \n\nby James Smith\n\nLobsters are supposed to be red right? ... Well, yes and no.\n\nMost live American lobsters are naturally colored an olive green or mottled dark greenish brown. In rare cases, lobsters come in shades of bright blue, white (albino), yellow, black, and red have been reported from time to time. Perhaps the most unusual colors are the "half-and-half" lobsters with a line straight down their backs where the two colors meet.\n\nThe major pigment in a lobster's shell, astaxanthin, is actually bright red in its free state; but in the lobster's shell astaxanthin is chemically bound to proteins that change it to a greenish color. When lobsters are cooked, heat breaks down these bonds, freeing the astaxanthin so that it reverts to its normal red color.\n\nSo how does a lobster turn bright blue? A genetic defect has been found that causes a blue lobster to produce an excessive amount of protein. The protein wraps around a small, red carotenoid molecule known as astaxanthin. The two push together, forming a blue complex known as crustacyanin which often gives the lobster shell a bright blue color. About one in a million lobsters are blue, but when cooked, it turns red like the other lobsters.\n\nIt has been suggested that more than 'one in a million' lobsters born are blue, but many do not survive because their bright blue shell brings too much attention to themselves, making them a prime target for predators. Scientists also believe that blue lobsters tend to be more aggressive than their normal colored counterparts. Since they don't easily blend in, they have adapted and changed to be more aggressive to protect themselves.\n\nThe blue lobster is truly another gift from Mother Nature that most people never see. Many professional lobstermen go through their whole lobstering career without catching or even seeing a blue lobster. Those that do have the privilege of catching one, are amazed and excited as it is seen as a once-in-a-lifetime event and feel a sense of awe when they experience seeing the strikingly beautiful blue lobster for the first time. Those that are caught are not normally eaten, but rather given to aquariums and educational institutions and kept on display in tanks for others to admire.\n\nTaxonomy of Homarus americanus:\n\nKingdom: Animalia Phylum: Arthropoda Class: Crustacea Order: Decapoda Suborder: Macrura reptantia Family: Nephrodidae Genus: Homarus Species: americanus

Ghost crabs live in burrows along the sandy beaches of the Eastern United States. The crabs can reach relatively large sizes of over 50 mm carapace width. They are omnivorous and will eat other crabs, clams, insects, vegetation, and detritus. Feeding activity takes place at night, while burrowing occurs during the day. Burrows show zonation with young crabs found closer to shore, near water. Older crabs tend to burrow farther from water. The large eyes of the crab are sensitive to changes in light intensity. The crab can produce 3 sounds: a rapping of the claw on the substrate, a rasping stridulation of the legs, and a bubbling sound presumably produced from the gill chamber. Combat between males is highly ritualized and rarely ends with contact.\n\n  \n  http://www.vims.edu/~jeff/ghost.htm

Notostracans (often just called Triops, tadpole shrimp or shield shrimp) are small crustaceans in the Branchiopoda group. Triops have internal compound eyes and a flattened shield covering the head and leg-bearing segments of the body. The order contains a single family, with only two extant genera. Their external morphology has not changed since the Triassic (appearance of Triops cancriformis around 220 million years ago). Triops cancriformis may therefore be the "oldest living animal species on earth" (Kelber, 1999).\n\nTadpole shrimps usually live near the ground of astatic pools, where they move with their ventral side down. However, lack of oxygen can force them to swim upside-down with their gill-like legs close under the surface of the water. Notostraca are omnivorous; they dig around in the mud using the frontal part of their shield, looking not only for plankton but also for larger prey such as worms, chironomid larvae and even weak tadpoles. Anostracans, often associated with notostracans, can also be a considerable part of their prey (especially when weak or dying).\n\nNotostracans sometimes even cannibalize freshly moulted members of the same species. In northern and central Europe, with few exceptions, all tadpole shrimps are female, whereas sex ratios in southern and western Europe as well as in northern Africa are near unity. These "females" possess hermaphroditic glands, but instead of selfing, parthenogenesis takes place. Modified appendages of the 11th pair of limbs bear the ovisacs with the mature eggs.\n\nTriops evolved to survive in naturally temporary ponds all over the world. As inhabitants of such, there has never been any pressure for them to become long-lived creatures. These ponds usually dry up during certain times of the year when there is no rainfall. Although the adult Triops die during these droughts, the embryos remain in a state of diapause (suspended animation) until the rains return and fill up the temporary ponds once again, making it safe for them to hatch.\n\nThe maximum life spans in the lab agree with data from field observations on Triops survival. In the lab, T. longicaudatus has a maximum lifespan of about 50 days and T. cancriformis a maximum lifespan of about 90 days, with some individuals beginning to die off as soon as 2 weeks after hatching. Secondarily, some may suffer premature deaths from moulting complications or other reasons.

Feeding Habits - Warmouths are carnivorous. Crayfish, shrimp, insects and small fishes make up the bulk of its diet. Most of its feeding is done in the morning, as it seems to sleep at night.

Paella. No I think they eat sea anemones or other coelenterates and encorporate their nematocysts.

There is a ton of disagreement on this subject.\n\nDo a search for lobsters and pain and you'll find sites that talk about both sides of the story.\n\nHey submitter, sorry you are too lazy to figure this out on your own. Like I said, there is a ton of disagreement. Some scientists will tell you one thing and some will tell you another. How is anyone supposed to have the "right" answer for you?

Marine invertebrates usually consist of the phylum porifera, cnideria, coelenterata, arthropoda and mollusca.\nInvertebrates like zooplankton are the major source of food for marine filter feeders like whales. Sponges are known for their beauty and some sponges are used as bath sponges.Jelly fish are useful scavengers.Arthropoda are widely used by humans as seafood -- namely crabs, prawns, lobsters etc. Mollusca are also used as seafood, and for the immensely profitable pearl industry.

Predators will eat just about anything, but it's unlikely that a coyote or anything else would just eat the genitalia and then walk away from a feast like that.  If not aliens, the most likely candidate would be people. Either pranksters toying with her, or the woman herself, possibly to continue her hoax.  I've heard crazier things.  So the latter isn't too unlikely.\n\nujjwal, what are you, like ten?  Does your mother know what you're doing?

The first clue should be where they are from.  The were located along the shores of the Pacific Northwest, this would point towards seafood.  For protein it would be mostly whale meat and salmon.  For some additional help you might try http://www.makah.com

I was going to say pseudo-scorpion, a very common arachnid related to scorpions and spiders, but with no tail stinger, but then I saw the size in your details.\n\nThe only critter I can think of in North America that could possibly be that large is one of the types of crayfish.\n\nHere is a site with some pretty good crayfish pictures: http://www.shrimpcrabsandcrayfish.co.uk/Shrimp.htm?crayfishamerica.html~mainFrame\n\nIf you were in more tropical climes, I would guess that it might be some form of crab, such as a land crab or robber crab.
