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.

Distribution	Saudi Arabian Gulf coast: preserved specimens held by the Smithsonian National Museum of Natural History (USNM) and published through GBIF, among them Safaniya (north of Safaniya Hill) (1982), Jurayd Island (north-east end) (1981), Abu Ali Island (1971). The GBIF records give Isabel Pérez Farfante as the determiner. Museum specimen records: not an estimate of abundance and not a statement about the species today.

A regional statement; the Saudi Gulf record of the species is the specimens named above. Reference 110 — Penaeus (Melicertus) latisulcatus sheet: geographical distribution · verified the evidence is a rendering of what the locator holds, not a verbatim quotation	Metapenaeus monoceros is the second most abundant commercially important shrimp species caught along the Saudi Arabian Red Sea coast … fishery-independent samples collected from shrimp trawling grounds off Al Qunfudhah and Jizan (October 2022–September 2023). Altogether, 10,859 specimens were examined. Saudi territorial waters, Red Sea Reference 12 — Abstract · verified the evidence is a rendering of what the locator holds, not a verbatim quotation According to the FAO sheet (1983): occurs throughout the area from South Africa to south India, including the Red Sea, Madagascar, Mauritius, La Réunion and Sri Lanka, but is “absent from the Gulf”; further east as far as the Malay Peninsula; it has entered the eastern Mediterranean through the Suez Canal. A regional statement; no range on the Saudi Gulf coast is attributed to the species.

Morphology	According to the FAO identification sheet (western Indian Ocean, 1983): carapace smooth; rostrum with 9 to 12 teeth on the dorsal margin and a single tooth on the ventral margin; gastrofrontal crest present; telson armed with 3 pairs of movable spines; no ischial spine on the first pereopod. Colour: body pale yellow to brown; dorsal crests dark brown; the pleura of the first 5 abdominal segments each with a short vertical red or brown stripe. A description for the western Indian Ocean (FAO Area 51), not a Saudi study. Reference 110 — Penaeus (Melicertus) latisulcatus sheet: distinctive characters · verified the evidence is a rendering of what the locator holds, not a verbatim quotation	According to the FAO identification sheet (western Indian Ocean, 1983): almost the entire body is pubescent (in East Africa, except the Red Sea, the pubescence is restricted to the dorsal part of the carapace and abdominal patches); rostrum with 9 to 12 teeth along the entire dorsal margin, straight, reaching as far as or beyond the tip of the antennular peduncle; telson armed only with spinules; a small ischial spine on the first pereopod. Colour: body pink, green-greyish or whitish with brown specks; antennae red. A description for the western Indian Ocean (FAO Area 51), not a Saudi study.

Habitat and distribution	According to the FAO sheet (1983): found from the coastline to depths of about 80 m, occasionally deeper, on sand or mud, with a clear preference in many localities for sandy substrates; nocturnal, burying in the seabed in daytime and emerging at night to feed. A description for the western Indian Ocean (FAO Area 51), not a Saudi study. Reference 110 — Penaeus (Melicertus) latisulcatus sheet: geographical distribution and behaviour · verified the evidence is a rendering of what the locator holds, not a verbatim quotation	According to the FAO sheet (1983): usually found from the coast to about 70 m (fished down to 170 m in an exploratory survey off Pakistan), mainly on mud, sandy-mud or silt; juveniles live in estuaries and backwaters or close to the shore.

Identity and names	WoRMS records the name Penaeus latisulcatus Kishinouye, 1896 as a “superseded combination”, its accepted name being Penaeus (Oleopenaeus) latisulcatus; the encyclopedia keeps the genus Penaeus as it does for its other species. Penaeus hathor is a separate accepted species that was originally described as a subspecies of P. latisulcatus.

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.
