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.

General description	The register holds no row for this field.	In FishBase this species sits in Lutjanidae, the snappers, in subfamily Lutjaninae within the teleost series Eupercaria. It is held as marine and reef-associated in a tropical climate, over a depth range of 3 - 150 m. The source gives a maximum length of 85.5 cm TL, a common length of 60.0 cm TL, a maximum published weight of 15.5 kg and a maximum reported age of 56 years. Its maturity range opens at 37 cm with no upper bound stated, and that figure is a maturity length rather than a maximum.

Morphology	The register holds no row for this field.	FishBase gives 10 dorsal spines with 15 - 16 dorsal soft rays, 3 anal spines and 8 anal soft rays. The source distinguishes a very deep body at a greatest depth of 2.1-2.4 in SL, greatly thickened lips in adults, a moderately developed preopercular notch and knob, a crescentic vomerine tooth patch, a smooth toothless tongue, gill rakers on the first gill arch totalling 17-18, and a truncate or slightly emarginate caudal fin. Colour is given as generally brown with a reddish tinge, each scale on the side bearing a pale brown border and 2-3 small bluish white spots, the head crossed by numerous undulating blue lines, the lips tan and the fins largely yellowish to dusky grey-brown. Juveniles are described with 3-8 brown bars on the sides and a chalky white spot with a broad blackish margin below the anterior soft dorsal-fin rays at the level of the lateral line, preceded by a black spot of similar size at mid-side.

Habitat and distribution	The register holds no row for this field.	The source holds this snapper as marine and reef-associated in a tropical climate, over a depth range of 3 - 150 m. FishBase reports it as occasionally encountered on coral reefs or shallow inshore flats, found singly or in small groups of up to 15 to 20 individuals. Adults are placed on deep coastal slopes, while juveniles are recorded on shallow algae-reef flats, often near freshwater run-offs.

Feeding	The register holds no row for this field.	FishBase records that this species feeds on fishes, cephalopods and benthic crustaceans. Reference 50 — FishBase species summary — Biology · verified	Only the second has a record

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.
