THE STRAIN-LIKE ORGANISMS ARE STRANGE AND THE LARGE MAJORITY OF THIS HAVE REMAINED IN SOFT BOTTOMS WITH VARYING DEGREES OF TISSUE FUSION (MANTLE AND PROTOLIMBS FUSION) AND IMPORTANT ADAPTATIONS FOR SUCKING BLOOD OR OTHER FLUIDS THAT ARE NAMED SIPHONS...THIS ORGANISMS LIVE IN SOFT AND IN HARD SUBSTRATES THEY ARE VERY PLASTIC THEY ADAPT EASELY THEY ARE THE RESULT OF A GREAT NUMBER OF DIFFERENT INVASIONS AND FOOD FIGHTS.....ANCHORAGE BY BYSSAL THREADS OR BY CEMENTATION TO THE SUBSTRATUM...REDUCTION OF LOSS OF THE FOOT OR OTHER LIMBS IS A NICE ADAPTATION IN A BLOODSUCKER THAT PREYS FOR AMBUSH LIKE GEORGES BUSH ABILITY TO DRILL INTO HARD SUBSTRATES ROCKS SHELLS CORAL AND WOOD IS A NATURAL EVOLUTION FOR MANY MANY GROUPS OF ORGANISMS... BURROWERS IN SOFT AND HARD BOTTOMS ARE GOOD SURVIVORS ... FOOD TRAPPED IN THE BOTTOM IN FINE PARTICLES IN THE DEEP SEA ...FORMATION OF THE GREAT FOOD GROOVES AND FUTURE OIL FIELDS ..ORGANISMS THAT FEED IN THAT BONANZA HAVE AN EXPLOSIVE EVOLUTION SOME SEVERAL MILLIONS OF YEARS AGO ...THE EVOLUTION OF FILTER FEEDERS IN THE BOTTOM OF THE GREEK OKEANOS LED TO THE EXPLOSION OF LAMELLIBRANCHS AND ISLAMIC STATE-LIKE ORGANISMS FOR THEY WERE NO LONGER CHAINED TO SCARCE FOOD SOURCES

THE MORE PRIMITIVE OF THIS NEW WAVE

OF FILTER FEEDERS 

ARE THE FILIBRANCHS 

THE MORE PRIMITIVE 

LAMELLIBRANCH CONDITION WITH

LITTLE MORPHOLOGICAL CONNECTION 

BETWEEN THE FOLDED GILL FILAMENTS 

IN THE SPECIALIZED CONDITION

THE FILAMENTS ARE FUSED TOGETHER

BY A VARIETY OF TISSUES 

AND TISSUE JUNCTIONS 

LIKE IN THE STRAIN  ....

EULAMELLIBRANCHS ARE STRAIN-LIKE 

ORGANISMS AND THE CHANNEL FOR 

BLOOD ...LEAVING THE FUSED GILL

RUNS ADJACENT TO THE TIPS OF THE 

ASCENDING LIMBS 

SCALLOPS DO NOT BURROW 

THEY ARE CAPABLE OF ESCAPING BY

SWIMMING LIKE MING IN MONGO....

CORRELATED WITH THE VAMPIRISTIC 

LIKE ORGANISMS OF THE STRAIN 

WITH THEIR RELATIVELY SLUGGISH 

HABITS AND THEIR LARGE SOURCE

OF OXYGENATED BLOOD

THEY SHOULD LACK RESPIRATORY 

PIGMENTS OF THEIR OWN

LIKE BIVALVES THAT HAVE A LARGE GILL

SURFACE .....
