Imagine peering into a vibrant rockpool, the sun glinting off the water, and suddenly spotting a miniature, translucent dancer! That's likely a Rockpool Prawn (Palaemon elegans), a common sight for snorkellers and divers exploring shallow coastal waters in the Mediterranean and North Atlantic. These little crustaceans, typically around 4cm but sometimes reaching 6cm, are fascinating to observe as they scuttle amongst the rocks, seaweed, and crevices. While they might not be as flashy as some reef inhabitants, their delicate beauty and active behaviour make them a rewarding find. You'll often see them in large groups, busily foraging for food or darting away from potential predators. Keep an eye out in depths of up to 30m, where they contribute to the rich biodiversity of the neritic zone. Rockpool Prawns are omnivores, meaning they'll eat just about anything they can find, from algae and detritus to small invertebrates. This makes them crucial players in the rockpool ecosystem, helping to keep things clean and balanced. They are also an important food source for larger animals, so they're always on the lookout for danger. The best way to spot them is to move slowly and observe carefully, as they are easily startled. Their translucent bodies, adorned with subtle markings, make them masters of camouflage, so patience is key!
Rockpool Prawns are easily recognised by their almost transparent bodies, allowing you to see their internal organs! Look for subtle brown or reddish markings along their bodies and legs. They have a distinct curved body shape and long, slender antennae that they constantly use to sense their surroundings. Their small size (typically 4-6cm) and lively, darting movements are also key identifiers. They are often found in groups, adding to their visibility.
