Marine species guide
Mediterranean fish
The Mediterranean rewards slow, observant diving. This hub gathers Scuba Steve species guides for fish and invertebrates common on Spanish, French, Italian and Maltese reefs, plus tips for temperate water ID.
What makes Med ID different
Visibility, seagrass meadows and rocky walls shape what you meet. Many animals are cryptic: seahorses, octopuses and scorpionfishes reward buoyancy control more than long swims.
Seasonal jellyfish blooms and dusky grouper encounters are classic talking points. Use species pages for mero, morena, pulpo and caballito de mar to sharpen your eye.
Starter species
Begin with dusky grouper, Mediterranean moray, common octopus, seahorse and jellyfish ID pages, then cross-link to Medes, Mallorca and Malta dive-site guides.
Bring a slate: note depth, substrate and behaviour before guessing a name.
Dive craft
Temperate water may need thicker exposure protection—see gear checklist posts. Plan slow reef circuits rather than chasing pelagics.
After dives, upload photos to Scuba Steve’s fish identification app to compare lookalikes.
Frequently asked questions
Are tropical fish present?
Some Lessepsian migrants appear in the eastern Mediterranean, but classic western Med reefs still centre on temperate assemblages.
