Thiony Simon

Name Opistognathus thionyi is kept in the honor of Thiony Simon (1985–2016), who passed away during preparation of this article. He collected most of the type material of the new species and dedicated his life to study and conservation of Brazilian reef ecosystems.

A new Jawfish, Opistognathus thionyi has been discovered near Brazil, Trindade Island, Dogaressa Seamount, and Fernando de Noronha Archipelago.What an interesting Opistognathus thionyi is with, chestnut brown to dark brown body color with five very irregular and poor defined dark bands, eyes reddish brown. So firstly this fish has been recorded from 10–65 m deep, and always in small burrows on sandy rubble bottoms. Therefore a hiding shy fish.

So certainly an interesting read about the all of the Opistognathus. Most importantly the complete set of papers on Opistognathus thionyi are with Zookeys. We have been finding quite many new species across the globe. So there could be many reasons of this from climate change to evolution, but surely the year isn’t over yet. In short there is still more to see.

Like always it's my day one in the hobby. Always been a hobbyist but never knew would dive so deep in the hobby. I too started with a freshwater aquarium. When I first started saltwater aquarium it just grew on me and I knew that had to do more in this hobby. I am a Post-Grad in Business Administration have worked with Coldstar Logistics, Amazon and Jindal's before jumping completely in the ocean. Other than aquarium hobby I have my interests in travel, digital games and consumer web technology.
