Flame helmet

Flame helmet (Cassis flammea) — field identification starting point: a marine mollusk whose shell/body form varies by group; use the scientific name, approved photo and shell or soft-body anatomy for exact identification.

Most are around 3 in (7.5 cm).

Up to about 6 in (15.4 cm) long (disc). Source: SeaLifeBase

What it eats isn't well documented yet for this species.

It lives on sand bottoms near seagrass beds in shallow water.

Found in Puerto Rico. Start in the documented habitat and substrate for this species, then narrow the search using depth, current, structure and food activity. Habitat reference:

Habitat: sand bottom and seagrass.

From 3 ft to 39 ft deep (1–12 m).

Search only legal collection areas and depths where the bottom can be inspected safely; closures and sanitary status matter more than a fishing depth number.

Water: marine. Habitat: sand bottom and seagrass.

Collect only during open legal/sanitary periods.

Use daylight/visibility and safe tide conditions unless local rules and experience support another approach.

Low water or low current can improve access/visibility, but never enter exposed reef, surf or mudflat conditions unsafely.

Choose sea state, wind and visibility that let you hold position and handle the fish safely. Avoid treating rough weather as a feeding advantage.

Identify the exact species, verify collection area/season/size and sanitary advisories, then use the least damaging legal collection method.

Let it go quickly if you're not keeping it.

BigJoe does not classify Flame helmet as a routine food species from the current source set. That is not a claim that it is poisonous; before eating, confirm exact identification, lawful retention, documented local food use and current public-health advisories.

Not a common food fish — most anglers release it.

Only harvest from an open, approved area and after exact species identification. Keep shellfish cold and clean. Scrub shells where applicable; for shucked mollusks, separate edible tissue with clean tools and prevent contact with contaminated seawater or surfaces. Shellfish sanitation closures override any recipe or cleaning advice.

For live clams, mussels and oysters, FDA guidance says to cook until shells open and discard any that stay closed. Cook shucked shellfish until firm and opaque. Only use shellfish from open, approved harvest areas; cooking does not reliably remove every marine biotoxin.

Shell edges, reef and contamination are the main risks. Wear protection and never eat shellfish from an area with an active closure/advisory.

No species-specific size, bag or season limits are listed here.

Avoid needless kills and follow protected-species, area and season rules.
