What if your deep-sea habitat was less rocky and more fleshy? That’s right, the time has come to talk all about deep-sea parasites and their fascinating life cycles.
We couldn’t think of anyone better to speak with than Dr Rod Bray, a pioneer in deep-sea parasitology research. Rod talks us through the captivating world of parasitic worms and his ongoing research into their ecology.

We couldn’t think of anyone better to speak with than Dr Rod Bray, a pioneer in deep-sea parasitology research. Rod talks us through the captivating world of parasitic worms and his ongoing research into their ecology.
Continuing with the parasitic theme, Thom and Alan share their critiques (and also their love for) ‘The Last of Us’, an apocalyptic TV show involving fungal parasitology. The news is somewhat less parasite-y this month with Alan officially extending the depth records for several taxa and there’s a new species of cavefish described! Don also provides a highly unexpected story from his days as Captain of a submarine...

Glossary
Cercaria - Offspring of digenean parasites.
Chimaera - A group of cartilaginous fish mostly found in deep waters.
Competition - A type of symbiosis where both species are harmed.
Commensalism - A type of symbiosis where one species benefits and the other is unaffected.
Ctenophore - “Comb jelly” marine invertebrates found worldwide.
Digeneans - A class of trematodes consisting of parasitic flatworms with two suckers.
Ectoparasites - Parasites that live on the skin of the host.
Elasmobranch - The subclass of cartilaginous fishes consisting of sharks, skates and rays.
Emmensalism - A type of symbiosis where one species is harmed and one is unaffected.
Endoparasites - Parasites that live inside the tissues of the host.
Facultative symbiosis - A type of symbiosis which is optional; not necessary for survival.
Flukes - “Trematoda” is a class of flatworms. They are internal parasites with a complex life cycle requiring at least two hosts.
Hydrozoan - A class of cnidaria. They are small predatory animals, most are benthic and involve a polyp stage.
Monogeneans - A group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish.
Mutualism - A type of symbiosis where both species benefit.
Myxozoa - A group of aquatic parasites which contains some of the smallest animals known to exist.
Neutralism - A type of symbiosis where neither species benefit nor are negatively affected.
Parasitism - A type of symbiosis where one species benefits and one is harmed.
Parasite burden - A measure of the number and virulence of the parasites that a host harbours.
Symbiosis - “Living together” two different species living closely together.
Teleosts - “Bony fishes”.
Tunicate - These are marine invertebrates sometimes called “sea squirts”.
