Its shallow burrow can be U-shaped. [source]

Florida and local context

Florent Charpin’s species gallery identifies the photographed animal as Pseudosquilla ciliata and explicitly captions the photograph Blue Heron Bridge, Florida. This is a source-labeled photograph, not an independently reidentified voucher or a current sighting guarantee.

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

Sources: Named-site photograph: source identification, not independently reidentified

How to recognize this animal

A checkerboard pattern on the stalked eyes is a useful clue. The elongated body may be green, yellow, brown, black or cream, and can be plain, striped or mottled.

Sources: UC Berkeley, Roy Caldwell: Pseudosquilla ciliata

Size and life stages

Caldwell’s account gives 20–95 mm. That span is 2–9.5 cm and is not a measured Blue Heron Bridge population range.

Sources: UC Berkeley, Roy Caldwell: Pseudosquilla ciliata

Habitat and where to look

Uses sandy bottoms near reefs, reef flats and grass beds. Adults dig shallow U-shaped burrows; juveniles can occupy cavities in rock.

Sources: UC Berkeley, Roy Caldwell: Pseudosquilla ciliata

Range and local context

The account describes tropical and subtropical occurrence outside the American west coast. The exact local evidence remains the named Blue Heron Bridge photograph.

Sources: UC Berkeley, Roy Caldwell: Pseudosquilla ciliata

What is on the menu?

A spearing predator of small crustaceans, worms and small fishes. It is not appropriate to borrow shell-smashing claims from unrelated club-bearing mantis shrimps.

Sources: UC Berkeley, Roy Caldwell: Pseudosquilla ciliata

Daily habits and behavior

Active by day and able to forage away from its burrow; the account reports burrow closure at night. This is species guidance, not a promise of a daytime encounter.

Mating and the next generation

No species-specific breeding schedule, clutch size or local spawning season was verified in the source used here. Burrow occupancy alone does not establish mating or egg care.

Look-alikes and identification traps

Color varies too widely to identify it by color alone. Check the patterned eyes and body form; an animal disappearing into a hole may remain unidentified.

Sources: UC Berkeley, Roy Caldwell: Pseudosquilla ciliata

Observe without disturbing

Leave burrow entrances clear. Do not use a pointer, food or fingers to draw the animal out; photograph only what it exposes voluntarily.

Harvest, protection and eating safety

Unknown: exact harvest rules need verification

The neutral gray status means the rules or scope have not been fully verified. Exact species and jurisdiction clearance remains unresolved. Unknown is not a protected or prohibited classification.

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?

Pseudosquilla ciliata is a stomatopod, not an automatically covered food shrimp or listed cleaner/snapping shrimp. Exact take and gear rules require confirmation. This review does not establish a bag, size, method or season allowance for this exact taxon.

Florida seasons and areas

Annual season and current-trip openness are both unverified. Absence of a listed closure is not affirmative evidence of year-round harvest. 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?

Species-specific spearing clearance is unverified; do not treat a missing prohibition as permission. 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?

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.

Pseudosquilla ciliata is a stomatopod, not an automatically covered food shrimp or listed cleaner/snapping shrimp. Exact take and gear rules require confirmation.

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

Occurrence is supported by a named-site photograph, not an estimate of abundance or a guarantee of a current sighting.
The local identification is the cited photographer or publisher’s identification; it has not been independently reidentified from a specimen.
Broad range or non-Florida research does not establish abundance, spawning dates or encounter probability at this Florida site.
Unverified species-specific details are identified in the relevant section rather than inferred from related animals.
