Atlantic Butterfly Ray

Identification

An exceptionally broad disc and a very short tail give the Atlantic butterfly ray its distinctive shape. The outer corners of the disc are pointed, and the tail lacks the defensive spine found in the spiny butterfly ray. Fine, wavy markings can form a pattern across the upper surface; darker bars may cross the tail. The Smithsonian’s Atlantic butterfly ray account is the primary comparison reference for this profile.

Use the disc and tail together when making an identification. A partly buried tail may hide the feature you need, and a photograph that fails to show a spine does not by itself prove that none is present. Leave the animal undisturbed and retain a tentative identification when the view is incomplete.

A name worth checking

Older North American guides often placed this ray under Gymnura micrura, commonly called the smooth butterfly ray. The 2017 taxonomic revision recognized Gymnura lessae in the northern and central western Atlantic. Consequently, old range, growth or breeding statements attributed to G. micrura should not all be transferred to this species.

Eschmeyer’s Catalog of Fishes recognizes G. lessae and includes Florida in its range. That supports regional inclusion, without establishing a particular Stuart Scuba dive-site record.

Habitat, feeding and reproduction

The Smithsonian data report associates this bottom-dwelling ray with shallow coastal settings, estuaries and soft substrates. Listed prey include bony fishes, mobile crustaceans and mollusks. It gives birth to live young. These habitat and life-history details are linked to the current species account rather than assumed from the older name.

Responsible observation and rules

Keep fins above the sediment and allow a resting ray to remain covered. Do not brush away sand to inspect its tail. A photograph of its natural position is preferable to a clearer view obtained by disturbing it.

FWC’s general harvest guidance still imposes restrictions on species described as unregulated. No open-harvest badge is justified by this profile. Confirm current species, gear, jurisdiction and site rules before collection. This is a wildlife-identification guide, not an eating recommendation.

Quick quiz

• Which scientific name is used here? Gymnura lessae.
• Is its tail long and whip-like? No, it is very short.
• What separates it from the spiny butterfly ray? The absence of a tail spine, assessed with other features.

Current observation and collection guidance

This identification guide does not establish permission to collect or harvest this species. Check current FWC rules for Florida waters and possession or landing in Florida, and applicable federal rules for fishing in federal waters. Those jurisdictions are not interchangeable. Biscayne National Park and Florida Keys sanctuary zones can impose additional restrictions or closures. Verify the exact species, location and activity before any proposed take; no food-safety recommendation is made here.
