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.	FishBase places this snapper in the family Lutjanidae, subfamily Lutjaninae, within the series Eupercaria. The source describes a fish of marine, fresh and brackish water that is reef-associated and oceanodromous, in a subtropical climate of 16°C - 30°C. It records a maximum length of 150 cm TL, a common length of 80.0 cm TL, a maximum published weight of 12.0 kg and a maximum reported age of 31 years. The length at first maturity is given as 57.0 cm, which is a maturity length and not a maximum.

Morphology	The register holds no row for this field.	FishBase gives 10 dorsal spines with 13 - 14 dorsal soft rays, and 3 anal spines with 8 anal soft rays. The source describes a moderately deep body, its greatest depth 2.3 - 2.7 in SL, a poorly developed preopercular notch, a crescentic vomerine tooth patch, gill rakers on the first gill arch of 6-8 + 9-12 = 16-20 including rudiments, and scale rows on the back more or less parallel to the lateral line. The colour is generally greenish brown on the back, grading to reddish, with a silvery or whitish belly, and deep-water specimens are usually reddish overall. Juveniles are described with a series of about 8 white streaks and 2 blue ones across the cheeks. Reference 50 — FishBase species summary — Short description · verified	Only the second has a record
Habitat and distribution	The register holds no row for this field.	FishBase gives a depth range of 1 - 120 m for this reef-associated and oceanodromous species of marine, fresh and brackish water in a subtropical climate. The source calls it euryhaline and records juveniles and young adults from mangrove estuaries, the lower reaches of freshwater streams and tidal creeks, with adults often in groups around coral reefs. It adds that they eventually migrate offshore to deeper reef areas, sometimes penetrating to depths in excess of 100 m. Reference 50 — FishBase species summary — Environment: milieu / climate zone / depth range / distribution range; Biology · verified	Only the second has a record
Feeding	The register holds no row for this field.	FishBase describes this snapper as mainly nocturnal and records that it feeds mostly on fishes and crustaceans. Those two groups are the whole of the diet the source names. Reference 50 — FishBase species summary — Biology · verified	Only the second has a record
Distribution	The register holds no row for this field.	Global range: FishBase records the species as Indo-West Pacific, from East Africa to Samoa and the Line Islands, north to the Ryukyu Islands and south to Australia. The source adds that it has dispersed into the eastern Mediterranean, off Lebanon, by way of the Suez Canal, but that it is not well established there.

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.
