Water Type: Marine

Helice latimera is a species of crab belonging to the family Varunidae. These crabs are commonly found in intertidal zones, particularly in muddy or sandy substrates. They are known for their unique adaptations to their environment and play a crucial role in the ecological balance of their habitats.

Description & Characteristics

Helice latimera is characterized by its relatively small size, typically reaching a maximum carapace width of around 30 millimeters. Its carapace is typically smooth and slightly convex, with a distinct pattern of ridges and furrows. The crabs are generally brown or gray in color, with variations depending on their environment. They possess prominent chelipeds, or claws, which are used for defense and feeding. Their walking legs are slender and adapted for maneuvering across the substrate.

Habitat and Occurrence

Helice latimera is primarily found in intertidal zones, particularly in muddy or sandy habitats. These crabs prefer areas with moderate wave action and ample access to food sources. They are often observed in estuarine environments, where freshwater mixes with saltwater, creating a unique and diverse ecosystem. This species is commonly found in the Indo-Pacific region, extending from the coasts of East Africa to the western Pacific Ocean. Their distribution includes various marine zones, from the neritic zone, which encompasses the shallow waters near coastlines, to the intertidal zone, where they are most abundant.

Taxonomy

Helice latimera is classified within the Class Malacostraca, which comprises a diverse group of crustaceans, including crabs, lobsters, and shrimp. It is further categorized within the Order Decapoda, a group that includes all crabs, lobsters, and shrimp. Within this order, Helice latimera belongs to the family Varunidae, a family of crabs that are commonly found in coastal and estuarine environments.

Feeding

Helice latimera is an omnivorous species, meaning that it consumes both plant and animal matter. Their diet includes algae, detritus, and small invertebrates such as worms and mollusks. They are often observed scavenging on the seafloor, utilizing their strong chelipeds to break down food and consume it. Their feeding habits play an important role in maintaining the ecological balance of their habitats by recycling organic matter and controlling populations of other species.
