We found Trichoplax at Portobello Marine Lab (University of Otago) in November 2019, using microscope slides suspended in a display tank. We tried to cultivate them but lost them during Covid-19 lockdown. Found another one today. In total we have found 4, all of them are about 100um in diameter. We have video which makes us confident that this is Trichoplax (not a giant marine amoeba). If we can trap more and/or breed this one we will do DNA analysis to confirm that it is Trichoplax and whether it is a known (e.g. adherens) or new species.

Varios ejemplares.
Salinidad 6030 ppm.
Las últimas cuatro imágenes podrían corresponder a un macho, porque no he observado ningún otro ejemplar como él y en cambio hay numerosas hembras de E. marinum en la muestra. No he encontrado imágenes de machos de E. marinum en la literatura. Los machos de rotíferos son muy escasos y desconocidos para muchas especies.
@rotiferologist y @plingfactory ¿conocéis
referencias bibliográficas sobre esta cuestión? Parece poseer trophi lo que es poco frecuente en los macho de rotíferos.

Pentastomid Gecko Parasite
Identified as Waddycephalus on Bowerbird by Ken Walker: "The identification was made by a colleague at Melbourne University. It's a Crustacean nymph parasite of all things. Pentastomiasis (also known as Porocephalosis) is a disease caused by infection with pentastomids. Pentastomids or Rallietellids are endoparasites of the respiratory system of vertebrates, maturing primarily in carnivorous reptiles (eg. snakes). Adult and larval pentastomids can cause severe pathology resulting in the death of their intermediate and definitive hosts. These parasites have an indirect life cycle involving one of more intermediate host. A closely related parasite genus Raillietiella was found to use frogs as an intermediate host in frog eating snakes. Nymphs of Waddycephalus have been recorded in numerous taxa (e.g. dasyurids, elapids, geckos, skinks, frogs, and owls) but it is unclear whether these animals are viable intermediate hosts or accidental hosts in which the parasite will not develop further or will transfer to other hosts. Considering the diet of known definitive hosts of Waddycephalus, frogs and/or lizards are the most plausible intermediate host for these parasites.
