Here is every native freshwater fish species of the Azores islands.
1) The European eel.
That is it!
Found this individual on São Miguel Island, Azores 🇵🇹
On many remote islands only diadromous species can access the freshwater habitats resulting in low species diversity.

There are more individuals of the deep-sea fish Cyclothone than any other vertebrate genus, maybe as many as one million billion. Distinctively ornamented ichthyoliths place the origin of Cyclothone in the greenhouse world of the early Eocene, ~55.6 Ma. royalsocietypublishing.org/rspb/article...
Happy to share with you the completely updated assessment of the conservation status of Europe’s 559 known freshwater fish species. Not happy to report that nearly 50% of them are threatened.

New paper led by @taylorblack.bsky.social shows AVT modulates aggression in darter lineages with nest site territoriality and paternal care but elicits no behavioral response in a species that secondarily lost territoriality and care www.sciencedirect.com/science/arti...
Abstract. The hagfish eye is highly reduced, lacking pigment and a lens, and covered by soft tissue. The timing and mode of this loss of complexity remain
Salmonids have a remarkable ability to form sympatric morphs after postglacial colonisation of freshwater lakes. These morphs often differ in morphology, feeding and spawning behaviour. Here, we…
