Mycteroperca rosacea
Rosy-brown grouper with leopard spots, logged across Baja California, Mexico in water from 20.6 to 26.8C year-round.
Grows to around 60 cm and shows a rosy to olive-brown body covered in dark, irregular leopard-like spots that give it its name. Body is deep and robust with the classic grouper profile: a large mouth, rounded fins, and a heavy-set head. Colour can shift between rusty red and greyish brown depending on mood and background, but the spotting pattern stays the giveaway feature.
Usually seen hovering or resting near rocky ledges and reef structure rather than out in open water, often holding a spot and watching divers pass rather than bolting. Most reports call it uncommon to rare at any given site, so a sighting tends to be a slow, patient reward rather than a guaranteed encounter, with a handful of sites in Baja producing very common numbers.
Like many groupers in the Mycteroperca genus, it is a protogynous hermaphrodite, meaning individuals can start life as females and later transition to males as they grow.
No clear seasonal pattern shows up in the sightings, and the species sits comfortably in 20.6 to 26.8C water, so it is worth looking for on any dive in Baja California year-round.
Baja California, Mexico is where this grouper turns up most consistently, with sightings logged across dozens of sites there. It is the only region with a strong data trail for this species, so Baja's rocky reefs and pinnacles are the reliable bet for divers hoping to find one.
Mapping where Leopard Grouper is logged…
Baja California, Mexico is by far the most reliable region, with sightings logged across a wide spread of local dive sites there.
There is no strong seasonal signal in the data, so it is seen year-round in Baja California in water between roughly 20.6 and 26.8C.
Look for a heavy-bodied grouper around 60 cm long with a rosy-brown to olive base colour covered in dark, irregular leopard-style spots. The spotting pattern and stocky grouper shape are the main clues.
They typically reach around 60 cm in length, a mid-sized grouper you will usually find resting near rock or reef structure rather than out in the open.
Most dive sites report it as uncommon or rare, though a smaller number of sites in Baja California see it very commonly, so sightings can vary a lot site to site.
