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: 36 — same: 4, differ: 22, only one side holds a record: 2, 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 coast off Jizan and Al Qunfudhah: the dominant commercial prawn of the fishery-independent trawl surveys of October 2022 to September 2023 (85,909 of 103,758 individuals, 83% by number). Saudi territorial waters, Red Sea Reference 11 — Abstract; Results 3.1 · verified
  • Saudi Arabian Gulf coast: a study published in 2019 examined the population dynamics of the green tiger prawn (Penaeus semisulcatus) at Dareen from May 2013 to April 2014; the maximum carapace length (CL) in the sample was 38 mm for males and 36.67 mm for females.

  • Saudi Arabian Gulf coast: preserved specimens held by the Smithsonian National Museum of Natural History (USNM) and published through GBIF, among them Tarut Bay (Ras Tanura) in 1973 determined by Isabel Pérez Farfante, Manifa in 1971 and Al Khobar in 1948.

  • According to the FAO sheet (1983): within the area from south and east Africa to India and Sri Lanka, including the Red Sea, the “Gulf” and western Madagascar, and further east as far as Korea, Japan, the Philippines, New Guinea and northern Australia; it has entered the eastern Mediterranean through the Suez Canal.

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.

  • According to the FAO identification sheet (western Indian Ocean, 1983): carapace smooth; rostrum with 5 to 8 teeth on the dorsal margin and 2 to 4 on the ventral margin; postrostral crest almost reaching the posterior margin of the carapace, with a distinct median groove; gastrofrontal crest absent; fifth pereopod with an exopod. Colour: body pale brown, sometimes greenish; carapace often with two yellow-cream dorsal transverse bands; abdomen with brown-grey and pale yellow dorsal transverse bands; antennae banded white and brown.

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.

  • According to the FAO sheet (1983): lives on the continental shelf from the coast to about 130 m, most abundant in less than 60 m on mud, sandy-mud or sandy-grit; forms small shoals; mostly nocturnal, burying in the substrate by day; mostly fished 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.
