Here read this.
The Cephalopoda are a group of molluscs characterised by large heads, muscular tentacles (modifications of the molluscan 'foot') and in most cases internalisation or loss of the typical molluscan shell. They move about in the oceans with the aid of fins, tentacles and jet-propulsion (water is taken into the gills and forced out through a fold in the soft mantle, termed the hyponome). Cephalopods include the octopuses, squid and cuttlefish, well known for their incredible colour-changing chromatophores and ability to squirt ink (which is convergent with gastropods such as the sea hare Aplysia ). Other important cephalopod groups include the pearly Nautilus, and the extinct Ammonoidea (including ammonites and goniatites), both of which have external, coiled shells.
Cephalopods are a rich source of insights into evolutionary convergence, perhaps the most celebrated example being the camera-eye, which includes also the pupil, correction for spherical aberration, retinal sensitivity, polarized vision, lateral asymmetry of eye use, and crystallin proteins. Other convergences in the sensory systems include the lateral line system and the oculomotor balancing reflex. The cephalopod brain shows interesting convergences, both in terms of anatomy (e.g. blood-brain barrier and cerebellum-like structures) as well as intelligence manifested in aspects of learning, memory, psychology, personality, social play and even a sort of tool use.
Complex behaviour among cephalopods includes lekking and use of a nuptial dance during courtship. Some cephalopods, notably cuttlefish and octopus, show highly accomplished mimicry and camouflage, based largely on changes in the colour and pattern of their chromatophores. Aspects of convergence in terms of anatomy range from the vertebrate-like structure of the cephalopod aorta to the possession of 'statolith' balancing organs and in one octopus (Ocythoe) even a fish-like swim-bladder. Regarding limbs and locomotion, the movement of octopus tentacles rather remarkably converges on the operation of a jointed limb even though there is effectively no anatomical similarity, and a number of small octopuses and the cuttlefish Metasepia pfefferi are known to engage in a form of bipedal locomotion.
Examples of convergence at the molecular level include the blood pigment haemocyanin, which is found in most molluscs and also arthropods, and elastic proteins in the aorta, which are reminiscent of those in the vertebrate heart. Powerful bioluminescence is employed by certain deep sea squid, and other squid have been found to possess bioluminescent 'reverse eyes', uniting them with many other marine and terrestrial animals that employ bioluminescence for signalling or vision.
The extinct ammonoids (ammonites and their predecessors such as goniatites) are well known for their coiled shell, and within the ammonoids we see interesting examples of convergence of shell shape. In addition to echoing patterns of change in shell shape in gastropods, a particularly important example of convergence among ammonoids concerns the pattern of morphospace re-occupation after a mass extinction. |

Aha you see it's funny because the content is unrelated to the title.

Cherry chocolate lamington sandwiches
Photography by Ben Dearnley
This beautiful dessert is cleverly put together for you to please with ease!
Makes 8
Ingredients
* 50g dark chocolate, chopped
* 415g can stoneless black cherries in syrup
* 1 tablespoon caster sugar
* 2 teaspoons cherry brandy (optional)
* 1/2 cup thickened cream
* 8 lamingtons
Add above ingredients to your shopping list
Method
1.
Place chocolate in a heatproof, microwave-safe bowl. Microwave on medium (50%) for 1 to 2 minutes, stirring every 30 seconds with a metal spoon, or until melted and smooth. Set aside to cool.
2.
Drain cherries, reserving syrup. Place syrup, sugar and brandy (if using) in a saucepan over medium heat. Cook, stirring, for 3 minutes or until sugar dissolves (don't boil). Increase heat to high. Bring to the boil. Reduce heat to low. Simmer for 5 to 6 minutes or until slightly thickened. Add half the cherries. Remove from heat. Chop remaining cherries.
3.
Using an electric mixer, beat cream until soft peaks form. Fold cooled chocolate into cream. Fold chopped cherries into cream mixture.
4.
Cut 1 lamington in half horizontally. Place base on plate. Spread with 2 level tablespoons cream mixture. Sandwich with lamington top. Repeat with remaining lamingtons and cream mixture. Spoon over syrup mixture. Serve.

Thank you, I found both subjects both entertaining and enlightening, true edutainment. Probably the best COAD post of 2011, would reccomend.
Trust me, I almost know what I'm doing. |

I for one and disgusted by your thinly veiled yet vicious racist attack. I'm sure you are quite smug in thinking that the targets of your vile insults won't comprehend your carefully constructed metaphors due to the language barrier and your general assumptions about their intelligence, but I assure you, you'll be found out soon enough.

Most goons probably stopped reading when he got to tentacles...and then started masturbating.
