Coloured SEM of a tick (Ixodes sp. ) in human skin
Feeding tick. Coloured scanning electron micrograph (SEM) of a tick (Ixodes sp. ) feeding head- down in human skin. Ticks are arachnids which parasitise mammals, birds and reptiles

Hedgehog flea, SEM
Hedgehog flea (Archaeopsylla erinacei), coloured scanning electron micrograph (SEM). The two structures protruding from the centre of the fleas head are sensory palps

Female tick feeding on a human leg

Hedgehog flea claws, SEM
Hedgehog flea claws. Coloured scanning electron micrograph (SEM) of claws at the tip of a hedgehog fleas (Archaeopsylla erinacei) leg. The claws help to anchor the flea to its hosts fur

Bat tick, SEM

Monitor lizard tick (Amblyomma exornatum, formerly Aponomma exornatum). This tick is native to Africa, where, as the name suggests, it is mainly a parasite of monitor lizards

Seal louse, SEM
Seal louse (Echinophthirius horridus), coloured scanning electron micrograph (SEM). This ectoparasite (external parasite) feeds on the blood of seals, but only when the seals are on land

Female lone star tick (Amblyomma americanum). This tick is found through the southeast and south-central United States. It is the vector for the spirochete bacteria Borrelia lonestari

Male yellow dog tick (Amblyomma aureolatum). This tick is the vector for the bacteria Rickettsia rickettsii in Brazil. Rickettsia rickettsii, causes the often fatal Rocky Mountain spotted fever (RMSF)

"Exploring the Intricate World of Ecto Parasites: From Head Lice to Fleas and Beyond" Delving into the microscopic realm, we uncover a captivating world teeming with ecto parasites. Through scanning electron microscopy (SEM), we witness the minuscule yet formidable head louse, its tiny claws gripping onto human hair strands like a tightrope walker defying gravity. Moving on, our attention shifts to the sheep tick, another notorious ecto parasite that attaches itself firmly onto its host's skin. Under SEM, its intricate mouthparts resemble a menacing apparatus designed for bloodsucking survival. But not all ecto parasites evoke fear; some offer intriguing spectacles. Enter the flea circus, where these agile creatures perform acrobatic feats under magnification. Their vibrant colors and delicate structures astound as they leap through miniature hoops and balance on invisible tightropes. Venturing further into this hidden world reveals unexpected wonders. Eyelash mite tails come into focus under SEM, resembling wispy appendages that navigate their way amidst eyelashes without detection by their unsuspecting hosts. Intriguingly grotesque yet medically significant is the medicinal leech – an ancient remedy for various ailments. Its segmented body and powerful suction cups are revealed in vivid detail through SEM imagery. Stepping away from SEM but no less fascinating is the light micrograph showcasing Trichodina parasite - a circular organism with cilia adorning its surface like ethereal hairs dancing in water droplets. For those seeking unconventional curiosities within this realm of parasites, look no further than the colored SEM image capturing a flea penis in all its peculiar glory – an anatomical marvel tailored for reproduction. Zooming out slightly from individual organisms brings us to fleas mating captured under SEM - an intimate moment frozen in time as nature perpetuates itself through these tiny insects' union. Shifting gears slightly but still within this captivating ecosystem, we encounter the white-clawed freshwater crayfish.
