Description

Haemulon album, commonly known as the Margate, is a species of grunt belonging to the family Haemulidae. It is characterized by its robust, oblong body and silvery-white coloration, often with subtle yellow or dusky markings. This species is a demersal fish, typically found in coastal waters over various substrates, including coral reefs, rocky bottoms, and seagrass beds. Margates are nocturnal feeders, preying on benthic invertebrates, and are known to form large aggregations during the day. They are a commercially important species in some regions and are also targeted by recreational anglers.

Coloration
Predominantly silvery-white to pale gray, often with a yellowish or dusky wash dorsally. Fins are typically dusky or yellowish. Juveniles may exhibit faint longitudinal stripes or blotches that fade with age. The inside of the mouth is typically bright red or orange, a characteristic of the grunt family.
Scale type

Distinctive features
Robust, oblong body, Large eyes, Thick lips, Bright red or orange mouth lining, Absence of prominent stripes or spots in adults, distinguishing it from many other Haemulon species.
Dorsal fin
Single dorsal fin, deeply notched, with 12 spines and 16-17 soft rays. The spinous portion is longer than the soft-rayed portion.
Tail fin
Moderately forked caudal fin.
Pectoral fin
Long and pointed pectoral fins.
Distinctive fins
Anal fin with 3 spines and 8-9 soft rays. Pelvic fins are thoracic.

Identification Tips

Coloration

Look for the overall silvery-white to pale gray body. Unlike many other grunts, adult Margates typically lack prominent dark stripes or spots on their flanks.

Mouth Lining

The bright red or orange coloration inside the mouth is a key diagnostic feature for the grunt family (Haemulidae) and is particularly noticeable in Margates.

Body Shape

Its robust, somewhat compressed, and oblong body shape helps distinguish it from more slender or deeper-bodied grunt species.

Fin Count

Counting the dorsal fin spines (12) and soft rays (16-17) can aid in positive identification, especially when differentiating from closely related species.

Habitat

Water type
saltwater
Depth
Typically found in depths ranging from 1 to 70 meters (3 to 230 feet), most commonly between 5 and 30 meters.
Environment
Inhabits coastal waters, preferring areas with hard bottoms such as coral reefs, rocky outcrops, and ledges. Also found over seagrass beds and sandy areas adjacent to reefs. Juveniles often utilize seagrass beds as nursery habitats.
Geographic range
Western Atlantic Ocean, from Bermuda and Florida (USA) south through the Caribbean Sea, Gulf of Mexico, and along the coast of Central and South America to Brazil.

  • Compatibility: Can be kept with other large, semi-aggressive fish. Not suitable for small or timid tank mates. May consume smaller invertebrates.
  • Special requirements: Requires a large tank with ample swimming space and plenty of rockwork for shelter. Good filtration is essential due to their size and feeding habits. May be shy initially but becomes more active once acclimated. Best kept singly or in very large aquariums with multiple individuals introduced simultaneously to minimize aggression.

Key Facts

Nocturnal Foragersbehavior

Margates are primarily nocturnal feeders, venturing out at night to forage for benthic invertebrates. During the day, they often aggregate in large schools near reefs or other structures.

Grunt Soundbehavior

Like other grunts, Margates produce a characteristic 'grunting' sound by grinding their pharyngeal teeth together. This sound is amplified by their swim bladder and is thought to be used for communication, especially during schooling or when threatened.

Mouth Colorationinteresting

The bright red or orange coloration inside the mouth is a distinctive feature of the grunt family and can be a useful identification aid for Margates.

Ecological Roleinteresting

As benthic invertivores, Margates play an important role in reef ecosystems by controlling populations of various invertebrates and contributing to nutrient cycling.

Safety Information

Safe
  • Safety level: safe
  • Venomous: No
  • Edibility: edible
  • Handling notes: Margates are not venomous. However, like all fish, they possess sharp fin spines that can cause painful punctures if not handled carefully. Use gloves or a fish gripper when handling to avoid injury. They can also produce a 'grunting' sound by grinding their pharyngeal teeth, which is harmless.

Similar Species

White Grunt

Haemulon plumierii

The White Grunt typically has a more yellowish-white body with distinct blue stripes or spots on the head and body, which are absent in the Margate. The Margate is generally larger and more robust.

Smallmouth Grunt

Haemulon chrysargyreum

The Smallmouth Grunt is more slender and has prominent yellow stripes along its body. Its mouth is also noticeably smaller than that of the Margate.

French Grunt

Haemulon flavolineatum

The French Grunt has distinctive yellow stripes on a silvery body, often with a series of oblique stripes below the lateral line. It is generally smaller than the Margate.
