Palaemonidae
The Common Prawn, *Palaemon serratus*, is a delightful crustacean frequently encountered by divers and snorkellers in the North Atlantic. These little guys, typically around 7cm but occasionally reaching up to 11cm, add a splash of character to rocky reefs and seagrass beds. What makes them special is their adaptability; they thrive in a wide range of depths, from the sun-drenched shallows to depths of 40 meters. Keep an eye out for them scavenging amongst the seaweed or darting between rocks – they're always on the lookout for a tasty morsel!
Common Prawns are easily recognizable by their translucent bodies, often tinged with a greenish or brownish hue. A key identifier is the prominent, saw-toothed rostrum (the pointy bit on their head), which gives the species its name *serratus*. Look for dark bands or spots along their bodies, and their long, slender legs which they use to deftly navigate their environment. Their behaviour, a quick darting movement followed by a pause, is also a good clue.
