COMPARE

Compare two species

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.

Morphology	The register holds no row for this field.	According to the FAO identification sheet (western Indian Ocean, 1983): carapace hairless; rostrum slender and long, with 7 to 9 teeth on the dorsal margin and 4 to 6 on the ventral margin; gastrofrontal and hepatic crests absent. Colour: body pale pink to yellowish, semi-translucent, with olive-green to grey-blue speckles; rostral and middorsal abdominal crests mostly brown.

Habitat and distribution	The register holds no row for this field.	According to the FAO sheet (1983): lives on shelf areas from the coast to about 90 m, most abundant in shallow water of less than 30 m on sand or mud (a slight preference for sandy bottoms); very euryhaline, tolerating salinities of more than 45 in the Red Sea (the unit symbol is illegible in the source copy read); caught by day as well as at night.

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.
