In 2020, CollectA introduced a Horseshoe crab model. These animals are members of the Limulidae family. This model of an ancient invertebrate is extremely detailed. The Horseshoe crab lineage has a fossil record that dates back to the Ordovician. Team members were asked to take some photographs of the figure for a palaeontology related project.

The CollectA Horseshoe Crab Model
The model is very detailed, and the paint scheme makes this replica look extremely realistic. However, it is on the underside where the care and dedication of the design team really shows.

The small chelicerae (modified claws) are bent towards the mouth. These appendages pass food into the mouth. The walking legs show the bifurcated end segments, and the rear “pusher” leg is clearly visible. The design team have included a vent at the base of the long, pointed telson.

The picture (above) shows an Atlantic Horseshoe crab (Limulus polyphemus) in ventral view. It is on display at the London Natural History Museum.
In horseshoe crabs, the head and thorax are fused. This structure is called the prosoma. It is also sometimes referred to as the cephalothorax. The cephalothorax is covered in a hard, protective carapace.
