Did you know
Cats seem to possess at least 10 times as many vocal sounds as their canine rivals -- more than 100, as compared to the paltry 10 of man's best friend.
It's unclear who's doing the counting or how they are doing it -- those figures sound a little too precise -- but it is definitely true that cats communicate more vocally than dogs do.
You see, dogs have mastered the noble art of Marcel Marceau -- the art of the mime.
A faithful canine companion knows that with some simple contractions of the facial muscles, she can produce an expression that will tug on the heartstrings or warn the owner of her imminent displeasure. She is content to practice this art in silence because she knows that all it takes is a look of pitiable pleading and her food dish will be filled.
The cat, meanwhile, is a haughtier animal. While dogs pay homage to their owners as the breadwinners of the pack, cats believe that humans are, at best, their equals. Instead of engaging in the undignified but effective ploys of the dog, cats are happy simply to order us about. The fact that their orders may or may not be heeded is a sign of our defective character, rather than their own lower status in the household.

Did you know that Lobster's blood is colorless?
When exposed to oxygen, it develops a bluish color.
What is “tomalley”?
Tomalley is the lobster’s liver. It turns green when cooked and is considered a delicacy.
What is the coral colored material often seen in a cooked lobster?
Coral is the egg mass of a female lobster. Cooking colors the tiny eggs a deep coral or red.
Lobsters grow by molting. This is the process in which they struggle out of their old shells while simultaneously absorbing water which expands their body size.
This molting, or shell-shedding, occurs about 25 times in the first 5-7 years of life. Following this cycle, the lobster will weigh approximately one pound and reach minimum legal size.
A lobster at minimum legal size may then only molt once per year and increase about 15% in length and 40% in weight. No one has yet found a way to determine the exact age of a lobster.
However, based on scientific knowledge of body size at age, the maximum age attained may approach 100 years. They can grow to be 3 feet or more in overall body length.

Did you know thatgoldfish can see both infrared and ultraviolet lightGoldfish, in particular, have been widely used as a model system for the study of color vision. The goldfish retina contains rods and four cone types in juveniles, three cone types in adults. The majority of goldfish retina ganglion cells have center-surround organization and many are wavelength opponent goldfish evidence photopic spectral sensitivity functions reflecting both wavelength additive mechanisms and wavelength opponent mechanisms. Goldfish wavelength discrimination has been reported in many studies and found out to exhibit color constancy. the goldfish first developed full spectrum vision in order to see the micro-flashes of bio-luminescence and static electrical charges that tend to discharge when a sonar-hunter sends sound waves through micro-fauna rich waters in search of prey. It also proved effective in sensing various tell-tales that result from the bow-wave of a fast moving predator... Only later did they realize that they could track submarines, intercept trace reflections of communication lasers that took bad bounces of atmospheric interference, and even decode the ultra-faint eminations that are shed of trans-oceanic communication cables, and so much more.
