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.

Fields side by side

Fields shown: 35 — same: 3, differ: 5, only one side holds a record: 19, neither holds one: 6, each has its own: 2.

Distribution
  • 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.

  • Saudi Red Sea: 3,274 individuals (3% by number) in the fishery-independent trawl surveys off Jizan and Al Qunfudhah, October 2022 to September 2023. Saudi territorial waters, Red Sea Reference 11 — Results 3.1 · verified
Differs
Morphology
  • 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): 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. A description for the western Indian Ocean (FAO Area 51), not a Saudi study.

General description
  • Maximum total length (TL) printed by the FAO sheet (1983): males 15 cm, females 20 cm. It is a maximum recorded total length, not a common size and not a measurement made in Saudi waters; the Saudi measurements on this page are carapace lengths and are shown separately.

Sources Differs

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.
