Once again, Monday’s are my Sunday’s so here is a VERY motivated Bluehead Chub for Bluehead Chubs are known as the “architects of the streams” due to their strong motivation to make nesting mounds pebble by pebble.

Totally out of my comfort zone here but I’ve gone for the Anchor Tuskfish as my motivational as it’s possibly the first tool using fish discovered. It tenaciously uses rocks to break open mollusc shells.

For this weeks motivation theme fro I decided to go with something mythical - How a Koi became a Dragon.

A school of golden koi was swimming upstream the Yellow River in China. Gaining strength by fighting against the current the school glimmered as they swam.

Here an interesting paper regarding the effects of salmon declining body sizes for the ecosystems they inhabit. https://t.co/NpR9p0CFfM

Since my first was only a few months ago, I decided to do a different sunfish: the Opah.

An awesome ambush predator, the is found in UK rivers, lakes and canals. With tiger-like stripes, this ferocious hunter is easily identified by a row of dorsal spines and orange fins

I think my first entry was for the themed fish. Here is a new take on Lacipenfu the in early Ken Sugimori style using ink & watercolor.

An old that fits this week's theme of "Fish that live inside other animals" - many species of cichlids are maternal mouthbrooders, meaning baby cichlids live in their mom's mouth until they are big enough to avoid predators!

The bladefin bass (Jeboehlkia gladifer)

Offtheme and I couldn’t decide so I’m posting both. Tope shark ( locally soupfin) - recently assessed as overexploited in SA. This species has been fished for over a 100 years in the Western Cape.

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.

Back to a watercolor attempt for this week’s Theme is fish. Though not truly endothermic, this Indo-pacific sailfish, have heat-producing tissue derived from the superior rectus eye muscle that warms their brain and eyes
