Two published records side by side, field by field. Each row says in words whether the two sides are the same, differ, or only one holds a record, and each empty cell says why it is empty. Only published records appear, and every value carries its reference.
Fields side by side
Fields shown: 15 — same: 4, differ: 7, only one side holds a record: 0, neither holds one: 2, each has its own: 2.
Measured specimen length
The length of a measured specimen, not the maximum length of the species.

An empty cell describes the register, not the animal: it does not mean the value is zero, or that science does not know it. A row carrying a state phrase ("unknown", "not recorded in the source") holds an explicit record saying so. A local name recorded for a sea is not an occurrence record, and a value two records share does not make them one record.
What the words in the comparison column mean
Same
Both sides hold the same value.
Differs
Both sides hold a value, and the two values are not the same.
Only the first / only the second has a record
The other side holds no row in the register for this field, and its cell says why.
Neither has a record
Neither side holds a row for this field.
Each has its own
A field whose two values are not compared: two identifiers, two plates; each record has its own.
