Copper deepwater sea fan with open, non-interconnected flattened branches and grooved twig tips.
Original educational illustration; not a photograph, occurrence voucher or exhaustive identification key. adult colony Version 3 removes pale terminal bulbs and provides visibly flattened fan branches with forked and grooved terminal ends. Noninterconnecting copper fan and basal holdfast intact.

Fun facts for your next surface interval

  • Its branchlets do not form a closed mesh. [source]
  • Polyps occur along branch sides. [source]
  • Grooved twig tips are a useful identification clue. [source]

Florida and local context

Florent Charpin’s individual photograph page identifies Iciligorgia schrammi and explicitly places that photograph at Palm Beach, Florida.

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

Sources: Biology or local occurrence reference

How to recognize this animal

A stiff, flat fan with flattened branches that fork but do not reconnect. Terminal tips are indented or grooved.

Sources: Biology or local occurrence reference

Size and life stages

The field guide reports 1 to 4 ft. (30 to 120 cm). Its measurement axis and sampling scope are not specified, so this is not presented as a verified maximum or life-stage range.

Sources: Biology or local occurrence reference

Habitat and where to look

Commonly found on deeper current-exposed slopes, walls and crevices; NSU says usually below about 15 m, though the full range is broader.

Sources: Biology or local occurrence reference

Range and local context

The local field guide lists Caribbean, Bahamas, Florida. The corridor evidence is a historical record from Palm Beach, Florida, not a survey of present distribution.

Sources: Biology or local occurrence reference

What is on the menu?

Coral polyps use tentacles and stinging cells to capture food. NOAA also describes collection of fine organic particles by many corals. This is general coral feeding context; no species-specific prey list, feeding rate or balance of energy sources is asserted.

Sources: Biology or local occurrence reference

Daily habits and behavior

Fans can vibrate in strong currents. It can look black underwater despite red-brown or copper coloration.

Sources: Biology or local occurrence reference

Mating and the next generation

Species-specific reproductive details and a local spawning calendar were not verified in the recovered evidence.

Look-alikes and identification traps

Gorgonia sea fans have interconnected branchlets. The open branching and grooved tips help separate this species.

Sources: Biology or local occurrence reference

Observe without disturbing

Maintain buoyancy and distance. Do not touch, feed, collect, turn over, detach or reposition the animal or its substrate for a photograph. A historical locality record is not permission to harvest.

Harvest, protection and eating safety

Live collection only, where permitted

Verified listed-group live collection is conditional, not recreational food harvest or year-round trip clearance.

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?

Iciligorgia schrammi is an erect octocoral, not either prohibited Gorgonia sea-fan species. Only qualifying non-encrusting colonies fall under the live-collection allowance: maximum six octocoral colonies per person daily within the 20-organism aggregate, subject to other applicable limits; no power tools. Attached substrate within one inch of the base is conditional on remaining attached. Confirm quota/closure and exact site before collection. Current 50 CFR 622.1 Table 1 note 5 limits FMP octocoral management to the EEZ off NC, SC and GA, so 622.223(d) is not a blanket Florida ban; Florida and sanctuary/site requirements still apply. Listed marine-life organisms must be landed and kept alive with suitable life support; a recreational saltwater license is required and recreational sale is prohibited. Verify applicable possession and other special limits.

Florida seasons and areas

No affirmative annual season or current-trip openness is established. Check exact mapped boundaries before any take. Blue Heron Bridge designated dive-site waters prohibit marine-life collection, not all Palm Beach County fishing. Biscayne ornamental collection requires a superintendent collecting permit; its mapped seasonal fishing/possession closure runs March 1–May 31, effective March 2026, with properly stowed continuous transit excepted. Pennekamp protects specimens and coral, prohibits tropical-fish collection and spearfishing, and allows fishing only under its designated-area rules; it is not permission to collect ornamental invertebrates. Key Largo Management Area prohibits taking coral and other marine invertebrates. Its exceptions are commercial spiny-lobster and stone-crab trapping and recreational spiny-lobster hand/hand-gear harvest under applicable rules, not recreational collection of the crabs or other taxa here. Sanctuary Preservation Areas prohibit collection and fishing subject only to expressly stated exceptions. These site rules do not establish a corridor-wide prohibition.

Can it be speared?

Do not spear a live-only collection organism. FWC restricts spearfishing near public swimming beaches, fishing piers/bridges and jetties, and in state parks. The Long Key-north Monroe restriction concerns state waters; Key Largo Management Area separately prohibits spearfishing. Federal location alone is not clearance.

Is it safe to eat?

No exact-species, site-specific food-safety clearance or meal frequency was verified. Legal take does not establish safety; some marine toxins survive cooking and freezing. Check current Florida Health advice and shellfish-area status where relevant. No dated, species-matched local menu evidence was verified; recipes remain disabled.

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

  • Reconstructed after workspace loss; new independent source review required.
  • Local photos establish historical occurrence only; they were not independently reidentified.
  • Unverified reproductive and feeding details are deliberately left unknown.
