Florida and local context

Gymnothorax vicinus is a species-level row in the Blue Heron Bridge (WPB), Phil Foster Park report.

A documented past record does not establish present abundance or guarantee an encounter.

Size and life stages

Smithsonian reports a maximum of 122 cm. This is a source-specific upper length, not a typical local sighting size.

Habitat and where to look

Reefs and rocks within seagrass beds; listed at 2–280 m, usually shallower than 50 m.

Sources: Smithsonian Tropical Research Institute: Purplemouth Moray

Range and local context

Eastern, central and western Atlantic; New Jersey to Brazil in the west. Local inclusion rests on the supplied named-site survey, not this broad range.

Look-alikes and identification traps

Color varies greatly. Compare the mouth, iris and fin-edge pattern with other morays; do not provoke an open-mouth view.

Observe without disturbing

Keep hands and equipment away from holes and jaws. Do not feed, touch or corner a moray. This is observation advice, not a harvest assessment.

Harvest, protection and eating safety

Live-only collection; closed sites override

Verified listed-group live collection, not recreational food harvest and not a blanket protected-species designation.

This color is a qualified summary, not permission to collect or a guarantee that a particular animal is safe to eat.

Can it be hunted or harvested?

Muraenidae: listed ornamental group. Where lawful, land and maintain alive with adequate life support; five per species within 20 organisms daily, and ten within 40 in two-day possession. License requirements apply; recreational sale is prohibited.

Florida seasons and areas

No affirmative year-round season clearance is assigned. State marine-life requirements also apply in federal waters. Check the mapped site before any take. Blue Heron Bridge closes listed marine-life collection, not all county fishing. Biscayne prohibits ornamental collection without a superintendent permit and has a mapped March 1–May 31 fishing/possession closure effective in 2026, with a stowed continuous-transit exception. Pennekamp disallows tropical-fish collection and spearfishing. Key Largo Management Area prohibits tropical-fish take, marine-invertebrate take except specified lobster/stone-crab activities, and spearfishing. Sanctuary Preservation Areas prohibit fishing/collection except expressly stated exceptions. These are site rules, not whole-corridor bans.

Can it be speared?

Do not spear a live-only collection species. FWC allows specified nonlethal methods; no quinaldine. FWC restricts spearfishing near public swimming beaches, fishing piers/bridges, jetties and in state parks. The Long Key-north Monroe restriction concerns state waters; Key Largo Management Area has a separate prohibition. Federal location alone is not clearance.

Is it safe to eat?

Live-only collection is not recreational food harvest. No food-safety clearance, recipe or meal frequency is established. Consult current Florida Health guidance for the animal, capture site and consumer. A legal allowance does not establish that a catch is safe to eat. No dated species-matched local menu evidence was verified. Florida Health specifically includes moray eel among ciguatera-associated predatory reef fish; cooking and freezing do not remove ciguatoxin.

Muraenidae: listed ornamental group.

This review covers the Vero Beach–Key Largo Atlantic corridor: Indian River, St. Lucie, Martin, Palm Beach, Broward, Miami-Dade and Monroe counties. Florida Atlantic state waters and South Atlantic federal waters are distinct jurisdictions. Do not extend a state-water season tag to federal waters or transfer Atlantic rules to Gulf-side Keys waters. Park and sanctuary boundaries can override a species allowance.

Before you act: Confirm the species, date, exact management area, state or federal waters, gear, licenses and current local closures. A local occurrence record never grants permission to take an animal.

Identification and source cautions

Historical cumulative citizen-science occurrence is not an independently reidentified voucher or a current encounter probability.
Regional habitat, depth and range do not prove occurrence at every corridor site.
Maximum length is source-specific, not a typical encounter size.
Detailed local spawning and activity schedules were not verified.
