Imagine gliding along a vibrant coral reef, and suddenly, a miniature marvel catches your eye – the Brazilian Reef Octopus (Octopus insularis)! Though small, typically around 8cm but reaching up to 12cm, these cephalopods pack a personality punch. These octopuses are reef-associated and live in the neritic zone, so you'll find them hiding amongst the rocks and corals from the shallows down to about 45 meters. While not a common sight at dedicated dive sites (reported sightings are rare), the thrill of spotting one on reefs in the Caribbean or Eastern Pacific is a true diver's reward. Keep a sharp lookout for these masters of disguise!
The Brazilian Reef Octopus is small, rarely exceeding 12cm. Look for a mottled colouration that blends seamlessly with the reef environment, often changing rapidly as it moves. Its head is somewhat flattened, and its arms are relatively short and thick. When threatened, it might adopt a 'ball' posture or disappear into a crevice with incredible speed. The presence of iridescent blue rings can also distinguish this species.
