Like all anemones, metriduim anemones have stinging cells but do not pose a danger to divers who keep their distance. These large, pale anemones can reach up to one meter in height and are often found growing in colonies. ![]() Giant metridium anemones, Metridium farcimen, sprout all along the west coast of North America. As such, they have some unusual abilities including their ability to tolerate temperatures as cold as 30° F (below freezing!). Interestingly, these cartilaginous fish are not true eels, but members of the wolffish family. Wolf eels delight divers all along the pacific northwest, and may be found as far north as the Aleutian Islands. Divers can differentiate male and female wolf eels by their colors. Inside a den, divers may often spot a mated pair of wolf eels they mate for life and work together to defend their eggs from predators. ![]() Wolf eels are known to play with divers, and will even accept treats of sea urchins and shell fish directly from a brave diver's hand (not that this is particularly recommended).ĭuring the day, wolf eels hide in their dens in rocky ledges or coral.

The eastern pacific octopus can be difficult to spot because it can darken and lighten its skin to camouflage with its environment. Octopuses can change color by means of special skin cells known as chromophores. Like the giant pacific octopus, east pacific red octopuses can sometimes be spotted by looking for a midden pile marking a den. East pacific red octopuses average about 3 - 5 ounces in weight and slightly over 1 foot in length. This small, solitary octopus can be found along the west coast of North America from California to Alaska, and is most commonly spotted in temperate waters of bays and estuaries. The east pacific red octopus, Octopus rubescens, looks like a miniature version of the giant pacific octopus. While this may seem like great fun, having a mask or regulator pulled off could be dangerous, so divers would do well to exercise caution when interacting with a giant pacific octopus. The internet is awash with images of these playful animals suctioning onto diver's heads, arms, and even regulators. This creature is curious, and occasionally emerges from its lair to investigate and interact with divers, especially when treats are offered. Octopuses are highly intelligent creatures, and the giant pacific octopus is no exception. Divers can often locate a giant pacific octopus den by looking for discarded piles of shells, known as a midden pile, that the octopus tosses out after finishing a snack.

These reddish-brown giants average about 60 - 80 lbs, and the largest reported specimen was an astonishing 600 lbs and 30 feet across.
