Jeboehlkia gladifer, commonly known as the Swordtail Cardinalfish, inhabits the deep waters of the Caribbean. It features a distinctive elongated body and a unique sword-like extension on its tail, which aids in defense and communication. This elusive species thrives in rocky crevices and coral reefs.

Jeboehlkia gladifer, commonly known as the Longfin Dragonet, is native to the Western Central Atlantic. It is typically found in regions such as the Caribbean Sea and the surrounding waters of the Gulf of Mexico.

The Longfin Dragonet inhabits shallow marine waters, often found in coral reef environments. It thrives in tropical climates with warm water temperatures and clear, saline conditions. The species is usually found at depths ranging from 3 to 30 meters.

Jeboehlkia gladifer is adapted to life among coral reefs, where it can camouflage against the complex and varied substrates. It feeds on small invertebrates and plays a role in the reef ecosystem as both predator and prey. The species' long fins and body coloration aid in its camouflage, helping it to avoid predators while hunting.
