Results for “specimen”
Ichthyological terms, not general ones.
voucher specimen
Specimen housed in a permanent, usually museum, collection, ideally including detailed collection data such as date, location, etc.. Assigned a specific code in order in case later reference is required. May be a type specimen.
paratype
In zoological nomenclature, a specimen other than the holotype upon which a description is based, i.e., each specimen of a type series other than the holotype.
Used in 9 profiles
type
Can be used to refer to any taxonomic group, the characteristics of which are used for defining related, higher or lower ranking groups. For example, the type of a nominal species is a specimen (type specimen), the type of a nominal genus is the nominal species (type species), and the type of a nominal family is the nominal genus (type genus).

aff.
Abbreviation of the word 'affinis', meaning related but not identical to. Used in the fields of systematics and taxonomy when referring to undescribed specimens or populations that resemble, but are clearly different to, a described species.
atypical
Not conforming to type; an abnormal specimen.
Used in 1 profile
bycatch
Species other than the target caught incidentally when fishing with a net. Sometimes used when referring to aberrant specimens exported among shipments of wild-collected ornamental fishes.
Used in 49 profiles
cf.
Abbreviation of the word 'confer', meaning 'compare with'. Used in the fields of systematics and taxonomy to denote specimens or populations that resemble a described taxon but differ in some respects and thus may or may not represent a distinct species.
cheirotype
A type specimen of a species that only appears in an unpublished source.
cleithral spot
Variably-sized (depending on species), usually dark marking present in the cleithral area dorsal to the pectoral fin insertion. Normally visible externally in llive specimens.
Used in 17 profiles
clone
Specimen descended from and genetically identical to a single common ancestor with natural examples normally resulting from asexual reproductive events. Produced via parthenogenesis in some fishes.
designation
In icthyology, the nomenclatural act by which the type specimen of a previously or newly-established genus, subgenus, species, or subspecies is fixed via an express statement.
Used in 6 profiles
fork length
Length of a fish specimen measured from the tip of the snout to the end of the medial caudal fin rays, i.e., the deepest point of the 'fork' formed by the fin. Tends not to be used in systematics.
formalin
Aqueous solution of formaldehyde used as a preservative for biological specimens.
holotype
The single specimen designated as the name-bearing type of a nominal species or subspecies.
Used in 36 profiles
juvenile
Not yet fully mature though mostly similar in form to an adult specimen; young.
Used in 400 profiles
lamina circularis
Bony process or plate at the base of the first ( unbranched ) and second ( first branched ) ray of the pectoral-fin in most male specimens of the family Cobitidae. It is also known as 'Canestrini's scale'.
Used in 24 profiles
lectotype
In zoological nomenclature, a syntype specimen selected as the name-bearing type of a nominal taxon in the absence of a designated holotype.
Used in 6 profiles
monoecious
Having both the male and female reproductive organs in the same specimen; hermaphrodite. Opposite of dioecious.
name-bearing type
In zoological nomenclature, the biological type (normally either a genus, species, or specimen) that determines how a name is applied.
