Gordonopsis mazupo is a large homolid crab, with the holotype male measuring 33.4 mm in carapace width. [1] [3] The carapace is ovate in shape, distinctly wider posteriorly than anteriorly, with an inflated and prominently convex dorsal surface. The rostrum is relatively short and triangular, flanked by two longer pseudorostral spines.
Tachypleus tridentatus, commonly known as the Chinese horseshoe crab, Japanese horseshoe crab, or tri-spine horseshoe crab, is a species of horseshoe crab found in Southeast and East Asia, with records from China, Indonesia, Japan, South Korea, Malaysia, the Philippines, Taiwan, and Vietnam.
The smallest species is the mangrove horseshoe crab (C. rotundicauda) and the largest is the tri-spine horseshoe crab (T. tridentatus). [ 44 ] On average, males of C. rotundicauda are about 30 centimeters (12 inches) long, including a telson that is about 15 cm (6 in), and a carapace about 15 cm (6 in) wide. [ 45 ]
Latreilliidae is a small family of crabs. They are relatively small, long-legged crabs found on soft bottoms at depths of up 700 metres (2,300 ft) in mostly tropical and subtemperate waters around the world. [1] Their carapace is very small and doesn’t cover the bases of their legs, which protrude from the cephalothorax in a spider-like manner.
During these stages, the crabs use appendages stemming from the thorax to swim and will also have a large dorsal spine. [7] Crabs in the megalopa stage also live in brackish waters, but here they have a segmented abdomen, meaning their legs will no longer stem from the abdominal area. [ 7 ]
Charybdis natator, the ridged swimming crab, wrinkled swimming crab or rock crab, is a widespread Indo-Pacific species of swimming crab from the genus Charybdis. It gets its name from the ridges on the dorsal surface of the carapace. It is a crab species which is of minor importance in fisheries.
The crab seen fending off the lions is a freshwater crab of the genus Potamonautes. There have been 26 species discovered in South Africa as of 2023, with new species discovered in recent years.
The dorsal portion of the dactylus possess 65-80 densely packed projections called tubercles [5] These bony spine-like structures are more pronounced in males and, as seen in other crab species with tubercles, seem to be stridulatory organs for generating sound. [4]
