60+ Fishes That Start With R

Fishes that start with R include named species, larger groups, and common names that vary by region. Pair a common name with its scientific name when you need a precise identification. Several profiles in the original list assign the wrong scientific name or combine facts about different fish; the sourced clarifications below make those distinctions visible while preserving the full source article unchanged.

R-fish names that need a taxonomic check

Common names are useful search terms, but they are not always unique species labels. These examples correct mismatches in the original profiles:

Name in the source	Clarification	Why it matters
Redfish / red snapper	Sciaenops ocellatus is red drum. NOAA lists red snapper separately as Lutjanus campechanus.	The source misspells the red drum genus as “Scianops” and then calls it a red snapper. “Redfish” is a regional common name, so pair it with the scientific name.
Ragfish	Ragfish is Icosteus aenigmaticus. Siganus luridus is dusky spinefoot, also called squaretail rabbitfish.	The source attaches the ragfish profile’s reef and rabbitfish claims to the wrong fish.
Rabbitfish	FishBase records “rabbit fish” as a common name for Chimaera monstrosa, a chimaera. Rabbitfishes in family Siganidae are another group.	Shared common names do not make these fish close taxonomic matches; use the species name to identify which one is meant.
Red whalefish	The U.S. Fish and Wildlife Service identifies red velvet whalefish as Barbourisia rufa. FishBase identifies Melanocetus johnsonii as humpback anglerfish.	The source pairs “Red whalefish” with “Malacocetus johnsonii,” a combination not verified in the references consulted. Do not silently merge it with either name.
Reedfish	Reedfish is Erpetoichthys calabaricus. Etroplus suratensis is pearlspot.	The source gives the pearlspot binomial for reedfish, then later correctly identifies ropefish as E. calabaricus.
River shark	Name the species or genus before describing range, size, or reproduction. The river-shark genus Glyphis is documented in the Indo-West Pacific and Australian river/coastal habitats.	The source gives a broad Central and South American range and leathery egg-capsule claim without identifying a species; those details should not be generalized across river sharks.

For example, the ragfish’s name belongs with Icosteus aenigmaticus, not with a rabbitfish species. FishBase records Chimaera monstrosa as “rabbit fish,” but places it among chimaeras; the word rabbitfish is also used for Siganidae. A common-name match alone is therefore not enough to transfer habitat or behavior between entries.

Likewise, “redfish” should not be treated as interchangeable with “red snapper.” NOAA uses Sciaenops ocellatus for red drum and lists red snapper under the separate binomial Lutjanus campechanus.

The source also assigns Etroplus suratensis to Reedfish, then gives the correct reedfish/ropefish binomial later. FishBase records the former as pearlspot and the latter as reedfish.
