SCALAR. Mathematical term. An abstract quantity having magnitude but not direction, such as volume, mass, weight, time, electrical charge, and always indicated by a real number.
 
SERPULID. A polychaet worm which builds a calcareous tube, usually coiled.
 
SESSILE. Attached, therefore not moving.
 
SIPHONOPHORE. A type of jellyfish. The Portuguese man-o’-war and other spectacular forms belong to this group.
 
SIPUNCULIDS. Worm-like animals characterized (among other things) by the possession of an introvert, and of rough, cuticle-like skin. Capable of great expansion; contracted, some of them merit the name peanut worm.
 
SYNDROME. A group of signs and symptoms occurring together and characterizing a disease.
 
SYNONYMY. The various names used to designate a given species or group.
 
TAXONOMY. A sub-science of biology concerned with the classification of animals according to natural relationships and with the rules governing the system of nomenclature.
 
TECTIBRANCHS. A group of sometimes shell-less gastropods to which belong the sea-hares and bubble-shells.
 
TELEOLOGY. The assumption of predetermined design, purpose, or ends in Nature by which an explanation of phenomena is postulated.
 
TENSOR. A mathematical term for the stretching factor which is necessary to change one vector, or force, into another vector having a different amount of force and direction. (Thus, if one imagines a given force
A
traveling south at 40 miles an hour, and another force
B
traveling southeast at 60 miles an hour, mathematically to translate force A into force B, the factor which changes one into the other must have not only force and direction, but stretching power, to pull
A
equal to
B,
and that factor is called the
tensor
.) Tensor is the quantity necessary in Einsteinian physics to translate vectors from one set of co-ordinates (frame of reference) to another.
 
TEREBELLID WORM. A polychaet worm which builds a sandy or pebbly tube, cemented usually to the underside of rocks by its own mucus.
 
THIGMOTROPISM. An innate tendency to seek enclosing contact with a solid or rigid surface, as in a burrow.
 
TROPISM. Innate involuntary movement of an organism or any of its parts toward (positive) or away from (negative) a stimulus.
 
TURBELLARIAN WORMS. The large group of flatworms to which the polyclads belong.
 
UBIQUITOUS. Occurring everywhere (though not necessarily abundantly) in the total area under consideration.
 
VECTOR. A mathematical term for an abstract quantity such as velocity, acceleration, or force, having
both
magnitude and direction. It may also have position in space, but this is not necessary. A vector is symbolized or represented by an arrow.
 
XEROPHYTIC. Plants structurally adapted to withstand drought.
 
ZOOID. Individual member of a colony or compound organism, having more or less independent life of its own.
