NTR: fin fold
We should have a generic "fin fold" class. Note that neither TAO nor ZFA have this.
ext inherits a fairly minimal set of logical axioms from TAO:
[Term]
id: TAO:0000040
name: median fin fold
namespace: teleost_anatomy
def: "Surface structure that will develop into one of the median fins. Extends from dorsal surface of fish, caudal to the 8th somite, to the ventral surface ending at the caudal side of the vent." [ZFIN:curator]

Can we come up with a logical definition template for "X fin fold"?
Is an X fin fold always part of an X (currently it is for pectoral, but not the others? Or does it develop in to an X? If it develops into an X, can it also be part of an X?
- TAO:0000040 ! median fin fold [DEF: Surface structure that will develop into one of the median fins. Extends from dorsal surface of fish, caudal to the 8th somite, to the ventral surface ending at the caudal side of the vent.]
- TAO:0000102 ! dorsal fin fold [OBO_REL:part_of: median fin fold] [DEF: Region of the median fin fold that develops into the dorsal fin.]
- TAO:0000717 ! apical ectodermal ridge median fin fold [OBO_REL:part_of: median fin fold] [DEF: Apical ectodermal ridge that is part of the median fin fold.]
- TAO:0001069 ! ventral fin fold [OBO_REL:part_of: median fin fold]
- TAO:0005317 ! pectoral fin fold [OBO_REL:part_of: pectoral fin] [DEF: The functional webs of the paired fins. They arise as a consequence of apical fold (AER) expansion and of migration of the distal mesenchyme. The fin folds are delimited by a dorsal and a ventral striated epidermis. The cells of the epidermal basal stratum are positioned on a basement membrane. Directly beneath the basement membrane of each side there is an array of actinotrichs, fibers of the extracellular matrix which act as supportive elements of the larval fin folds.]
I think that use of pectoral or pelvic fin folds may not represent the developing fin bud or some precursor, but rather a part of the adult structure, and as such would be treated differently than the median fin folds, which give rise to the medial fins. to do- read http://www.sciencedirect.com/science/article/pii/S0925477398001762
Can we say that this new term was added at some point? https://www.ebi.ac.uk/ols/ontologies/uberon/terms?iri=http%3A%2F%2Fpurl.obolibrary.org%2Fobo%2FUBERON_2005316
