The Lobster Conservatory includes information on the biology and conservation of lobsters. The majority can be applied to crayfish due to common ancestry and homology. Neural and tail anatomy provides an idea of the organization of the segmental ganglia in the tail of the crayfish. The second diagram on the page is a transverse section through ...
In lobsters which have had a pereiopod (walking leg) cut off or been injected with the irritant lipopolysaccharide, the endogenous morphine levels initially increased by 24% for haemolymph and 48% for the nerve cord. [53] In vertebrates, opioid peptides (i.e., enkephalins) have been shown to be involved in nociception.
Caught lobsters are graded as new-shell, hard-shell, or old-shell. Because lobsters that have recently shed their shells are the most delicate, an inverse relationship exists between the price of American lobster and its flavor. New-shell lobsters have paper-thin shells and a worse meat-to-shell ratio, but the meat is very sweet.
Lobsters have two urinary bladders, located on either side of the head. Lobsters use scents to communicate what and where they are, and those scents are in the urine. They project long plumes of urine 1–2 meters (3 ft 3 in – 6 ft 7 in) in front of them, and do so when they detect a rival or a potential mate in the area. [18]
Consider the age of the eggs. Some people swear by the trick that older eggs make for easily peeled hard-boiled eggs. The recommended time to store your eggs before boiling is between one and two ...
In the South American freshwater genus Aegla, the young hatch from the eggs in the adult form. [1] Squat lobsters pass through four, or occasionally five, larval states, which have a long rostrum, and a spine on either side of the carapace; the first post-larva closely resembles the adult. [1]
To boil anywhere from nine to 12 Easter eggs at once, bring the water to a rolling boil, making sure the cover is on the pot and the heat is on its lowest setting. Cook your eggs for 20 minutes ...
The LLF consider boiling lobsters alive (the traditional method for cooking them) unacceptable and use direct action to prevent it. Their claim that lobsters, which possess a rudimentary nervous system, can feel pain, is the subject of ongoing scientific debate. [3] [4]
