Gelastocaris

Gelastocaris is a genus of decapod crustaceans belonging to the family Palaemonidae. These shrimp are commonly known as “ghost shrimp” or “glass shrimp,” a moniker they share with other transparent or translucent shrimp species. They are found in marine environments across the world, particularly in the Indo-Pacific region.

Characteristics

Gelastocaris species are characterized by their slender, transparent bodies. They typically have a length of 2-4 cm, and possess long, delicate antennae. Their coloration is often translucent or pale, allowing them to blend in with their surroundings. These shrimp have distinctive, elongated rostrums, a beak-like projection on their head, which are often toothed or serrated.

Environment

Gelastocaris shrimp prefer shallow coastal waters, often inhabiting areas with sandy or muddy substrates. They are typically found in coral reefs, seagrass beds, and mangrove swamps. Their translucent bodies provide excellent camouflage, allowing them to avoid predators and ambush prey.

Diet

Gelastocaris species are primarily scavengers, feeding on detritus, algae, and small invertebrates. They play an important role in marine ecosystems by cleaning up dead organic matter.

Reproduction

Gelastocaris shrimp reproduce through external fertilization. Females lay eggs that are attached to their swimmerets. The eggs hatch into larvae, which undergo several molts before reaching adulthood.
