But while pinworms are relatively benign as far as parasitic roundworms go, there are some that are nastier - like gut-dwelling, blood-feeding hookworms - and of the hookworms, those that infect seals and other pinnipeds are especially nasty - and this has something to with their host's life style. Speaking of nasty things that burrow in the belly of aquatic animals, this year we also featured a parasitic isopod that live in the belly of an armoured catfish.
And the, there are hosts that can't seem to keep their parasites all to themselves, for example, the introduction of the Burmese Python to Florida as resulted in a series of parasite exchanges between it and Florida's native snakes. So even if you end up living in a new location, you can never truly escape from your parasites - even for salamander living out their quiet lives in a cave, they can also become host to some hungry leeches.
But it's not just the parasites of vertebrate animals which get the spotlight here. This year the blog also featured posts on two parasites that give cicadas a bad time. One is a fluffy caterpillar that simply cling on to cicadas and suck their blood, while the other is a fungus that cause the infected cicada's butt to disintegrate. That fungus also seize control of the cicada's behaviour, and it is not alone in doing so. This year I also wrote a post about how the lancet fluke puts itself in the pilot seat of an ant.
Meanwhile, we continue to feature more student guest posts about topics such as a parasitoid wasp's bodyguard caterpillar, whale lice, how parasitoids are affected by what their hosts eat, the cuckoo's thicker egg shells, and a maggot that eat baby birds.
And for those who thought I was done with drawing Parasite Monster Girls, I have some bad news - I'm at again; meet the medically proficient Dr Delilah, and the elegantly composed Sayuri. They've even made their way out of the digital into the the physical realm, with prints of the Parasite Monster Girls being featured at the University of New England Library. I also recently got the opportunity to visit the Meguro Parasitology Museum which should be on the top of the bucket-list for any fans of parasites or parasitology.
That does it for this year on this blog, but until next year, you can continue to follow my parasite-related and other antics on my Twitter @The_Episiarch if you wish to do so. See you all in 2019!
