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: 34 — same: 3, differ: 9, only one side holds a record: 14, neither holds one: 6, each has its own: 2.

Distribution
  • Saudi Red Sea: recorded but rare, 17 individuals (0.02% 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
  • According to the FAO sheet (1983): within the area from south and east Africa to the Gulf of Aden and the Red Sea, the west coast of Madagascar, Mauritius and La Réunion, and from Pakistan to south India and Sri Lanka, extending east as far as China and Japan, the Philippines, New Guinea and Australia. A regional statement that does not name Saudi Arabia.

  • 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.

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.

Morphology
  • According to the FAO identification sheet (western Indian Ocean, 1983): carapace smooth; rostrum with 7 or 8 teeth on the dorsal margin and 3 or 4 (rarely 2) on the ventral margin; gastrofrontal crest absent; fifth pereopod without an exopod. Colour: body green-grey to brown, sometimes reddish or bluish; abdomen with dark brown to dark grey and pale yellow dorsal transverse bands; antennae uniform pink-brown. A description for the western Indian Ocean (FAO Area 51), not a Saudi study.

  • 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 coast to about 150 m, occasionally deeper; the largest concentrations are fished in less than 60 m on mud or sand, sometimes mixed with shell fragments; juveniles are found in mangrove swamps, estuaries or backwaters; more easily available at night.

  • 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.

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.
