Extremely sloppy
Sword fish and relatives have brain endothermy. Warmer brain and optic nerve benefit these organs when fish encounter steep thermal changes (e.g. deep dives). More in the paper by Wainwright and Longo https://t.co/FSxvC7xRnz

This week "endotherm fish", I figured we would see many Opah, so, I tried my luck with its stage. Fun but challenging task, as very few image exist, except from Matarese et al. 1989 drawings. I hope you'll like it! Its certainly not that accurate.

has scrambled my brain this week. The brief is to make a fish from an inanimate object. I’ve made the short leap from a box fish to a cardboard box fish. It turns out that cardboard is tricky to draw.

For this week the round goby seemed appropriate. This small benthic fish have been introduced in the Great Lakes in 1993 probably by ballast water. Territorial and aggressive, it remodeled a lot of freshwater benthic communities.

The brief this week was for a fish that you hadn’t heard of before.
In my reading up of Chondrichthyes I discovered Cladoselache fyleri who was a pre-Elasmobranch shark from the Devonian period.

So random function provided me the Yellow Spotted Catshark for this week a quite cute little shark who like to hag out in costal South Africa, down to 500m deep. New species learn, I guess the challenge is completed! ;)

For this I chose to do further research on an unknown cichlid. This is the Blunthead Chimba Red. Tropheus moorii is endemic to Africa’s Lake Tanganyika. 40 different color morphs are dispersed throughout the lake, ranging from dark green to flame red and yellow.
