they are highly intellengent and have the most complex brain of all invertebrates.

You are clearly referring to the Class Cephalopoda (squids, octopi, etc.).  It is in the Phylum Mollusca.  Most molluscs, however, have moderate to poor eyesight relative to arthropods and cephalopods (snails and clams are molluscs) so saying the Phylum Mollusca is the correct choice is a bit off.

Sperm Whale. I don't believe they kill their own kind over oil and religion so I'd say they were more intelligent than a lot of humans :)

Everything that lives on or in land or water or the sky is intelligent enough to have survived till now against a plethora of predators. The future will let us know if man is intelligent enough to survive the most dangerous predator of them all - MAN Himself!

This isn't exactly an animal but I'd say Ants or Bees, Even though their numbers can be in the millions or billions they are very uniform and work towards a common goal. Chaos coming together as one.

We may have a gallon of brain matter inside our heads,\nbut some, if not many of us, only have a shot glass of knowledge, reasoning, and logic up there.\n\nI mean, look at the Deep South of the US???\n\nAn entire hive of bees have more logic than the entire region.\n\nWill this be "to go"?

The cell doesn't think.  It merely reacts to chemical signals that it detects.  The same goes for protozoa.  I strongly doubt that ants and worms do also.  I doubt that there's enough nervous tissue to form an actual thought.  They are certainly more complicated than protozoa, but they work on instinct, not by making conscious decisions.\n\nThe lesson that you were taught in your high school biology class was an analogy, not the literal truth.  The cell nucleus does control what happens in the cell, but it doesn't think.  It merely contains the programs that operate the cell, in the form of DNA.

She is knowlegable and uses her brain.

Ants are neat, and while that other guy was right about 'intelligence' not being a concrete concept, ants certainly can solve very complex problems.  The definitely don't wander around aimlessly and randomly like someone else suggested.  They have  incredible cognitive abilities for navigating from food sources back to their nests.  One of these is known as path integration, ants are able to keep in their memory all the different twists and turns in their path to find food so that when they do find food they can head in a straight line back to their nest.  They are also able to learn the location of different objects in their environment and use these to find their way home if they get off course, like if they get blown away by the wind or something!  When you consider that an ant's brain is smaller than the head of a pin, the amount of information they are able to hold in there and remember and manipulate, is pretty astonishing.  Using electron microscopes and neuroscience techniques, scientists have identified tiny clusters of neurons on the brains of some ants, called mushroom bodies.  They think that these structures are the sites of memory and navigational cognition in the ants. You might also find it cool to know that the navigational systems of ants have formed the basis of the navigational systems developed using artificial intelligence for robots.  And as for the division of labor, I think you are spot on.  Ants (and other eusocial insects) provide the natural world's best examples of self-organising systems and they are way cool and very neat!!!  Science nerds rock-on!

Although humans have evolved to have the greatest level of intelligence on earth,  intelligence is not only the preserve of Homo sapiens. Many physical and behavioural characteristics of animals occur among a disparate number of species for example, even though the Thylacine or Tasmanian Tiger was a marsupial it had the physical and behaviour characteristics of a wolf. This is called parallel evolution. The same can be said for intelligence, for example, cephalopod mollusc's such as squid and octopus (the most intelligent invertebrates) and dolphins and whales have both evolved seperately to become highly intelligent within their realm. \nAs for a species being a 'threat' in the race for the most intelligent \nin the future, this is very unlikely as evolututionary processes work on the order of thousands of generations. It is also unlikely that humans will survive long enough for another species to supercede us as mammals as a species generally only live on the order of 1-1.5 million years (we have passed our due date!) say compared to insects that live between 10-15 million years as a species.\nThe biggest threat from an intelligent species is more likely to be extraterrestrial!?

As they are social insects and they live by division of labor and work in unison. They are closely knit by pheromones.

The conduction of food materials,water,etc is very essential for the survival of an organism.If u take the example of lower organism devoid of any specialized structures for conduction,the complexities of life processes are not as complex as that of the higher organisms.The specialized structures are more efficient,protective in their own ways and above all indispensable.If the complex life forms can carry out many processes at same time its because they get uninterrupted supply of oxygen,blood in case of higher animals,water and many materials at the same time .its all because of specialized structures.

The Annelida have bilateral symmetry .The annelids also have a one-way digestive system . It has a segmented anterior with 8 hearts in each. It also has a body cavity. \n\nThe Mollusks are also bilateral like the annelids. They have a good nervous system. They also have a one-way digestive system. They have a coelom like the . The classes of mollusks are the bivalves, which have two valves, which the name suggests. It has 2 shells and 3 layers also. It has a mantle and it lives in the water. It has gills and abductor muscles. It has an excurrent and incurrent siphon, which no other phylum has. There are the gastropods, which live in land and ocean. It has one shell and one foot. There are also the cephalopods, which has tentacles a foot that can either be a sucker or hook.

Ant brains are largest amongst insects.  Mushroom shaped brain appendages have function similar to the gray-matter of human brains.\n \nIt has been estimated that an ant's brain may have the same processing power as a Macintosh II computer.\n\nProbably not sentient in the way that we are. They cooperate with each other and have acute senses.
