Pomadasys incisus, commonly known as the Roncador or Bastard Grunt, is a species of marine ray-finned fish belonging to the family Haemulidae, the grunts. It is characterized by its moderately compressed, oblong body and a distinctive coloration. This species is known for the 'grunting' sound it produces by rubbing its pharyngeal teeth together, amplified by the swim bladder, a common trait among Haemulidae.

Body Shape and Coloration
Look for the moderately compressed, oblong body with a silvery-grey to brownish-grey back and lighter belly. Faint longitudinal stripes or rows of spots may be visible.
Lips and Mouth
Observe the thick, fleshy lips. The inside of the mouth is often distinctly orange-yellow, which can be a key identifier.
Chin Pores
Examine the chin for two distinct pores and a median groove, characteristic of the Haemulidae family.
Dorsal Fin
Note the single dorsal fin with a deep notch, typically with 12-13 strong spines and 13-16 soft rays.
Anal Fin Spines
Pay close attention to the anal fin, specifically the second anal spine, which is usually very robust and longer than the third spine.

Fatos principais
Grunting Soundbehavior
The common name 'grunt' comes from the sound these fish make by grinding their pharyngeal teeth together, which is amplified by their swim bladder. This sound is often produced when they are stressed or caught.
Nocturnal Foragersbehavior
Roncadores are primarily nocturnal feeders, emerging from their daytime shelters to forage for benthic invertebrates and small fish under the cover of darkness.
Habitat Generalistsinteresting
This species demonstrates remarkable adaptability, thriving in a variety of coastal habitats including rocky reefs, sandy flats, and even brackish estuaries, showcasing its ecological resilience.
Thick Lipsinteresting
The 'Rubberlip Grunt' alternative name refers to its noticeably thick, fleshy lips, which are thought to aid in foraging for prey on the seabed.
Informações de segurança
Seguro- Nível de segurança: safe
- Venenoso: Não
- Comestibilidade: edible
- Observações de manuseio: No specific handling precautions beyond standard fish handling practices to avoid fin pokes. The spines, while not venomous, can be sharp and cause minor punctures. Handle with care to avoid injury to both handler and fish.
Espécies similares
Striped Grunt
Pomadasys stridens
P. stridens typically has more pronounced and numerous longitudinal stripes, often extending onto the head. Its body is generally more elongated, and the second anal spine is usually not as robust or long as in P. incisus.
White Grunt
Haemulon plumierii
While not in the same genus, White Grunts (found in the Western Atlantic) share similar body forms. H. plumierii has distinct blue stripes on its head and body, and its mouth is typically white or pale inside, unlike the orange-yellow of P. incisus.
Smallmouth Grunt
Pomadasys rogeri
P. rogeri generally has a smaller mouth and a more silvery body without the distinct dusky markings often seen in P. incisus. The fin coloration and proportions may also differ subtly.
