Sometimes referred to as the “Ugly old man of the sea,” the Wolf Eel has a bulbous head with a strong jaw and sharp teeth. The adult Wolf Eel ranges from light brown to dark gray in colour, with a long, dot-covered body. These dots may differ in size and colour depending on the individual and its gender, and are frequently surrounded by a light ring. It is easy to differentiate between male and female wolf eels; the males tend to have larger, more grotesque heads, whereas the females possess a smaller jaw and are often darker in colour. Juveniles are a startling orange marked with dark orange splotches. The wolf eel’s dorsal fin extends from its head to the tip of its sleek body; its pectoral fins, located at the base of the head, are large and rounded.
The Wolf Eel has been found to live anywhere from Japan to the islands of Racerocks off of British Columbia’s coast. It tends to keep to shallow to medium depth waters, making its home in the hollows between rocks, which oftentimes look as though they would not be able to fit its wide head. The deepest a Wolf Eel has ever been uncovered is 225 meters below the surface.
The Wolf Eel is a rather intimidating-looking carnivore, adapted perfectly to suit its murky environment. Its jaw is designed especially for mowing down on hard-shelled creatures such as crustaceans, mussels, clams, sea urchins, snails, and some other fish.
Although full-grown Wolf Eels have next to no predators (save the occasional harbor seal), their eggs often fall prey to rockfish and Kelp Greenlings.
Wolf Eels are unique in the way they go about their lives because (despite how they may initially appear) they are in fact quite the romantics- they mate for life. These creatures seek out their partners at four years of age, but will not reproduce until around seven. The male will court his female first by bumping his head up against her abdomen, then enveloping her entirely with his long slender body. Females can produce up to an astounding ten thousand eggs at once. The parents will closely guard their offspring for a period of around sixteen weeks, until at last they hatch.

Tidepool Sculpin Common Name: Tidepool Sculpin Scientific Name: Oligocottus maculosus Size Range: up to 9cm (3.5 inches)
Common Name: Tidepool Sculpin
Scientific Name: Oligocottus maculosus
Size Range: up to 9cm (3.5 inches)
Identifying Features: All Tidepool Sculpins look very similar to one another, though distinct from other tide pool creatures. They have long, thin bodies with big heads and stripes all the way down the length of their body. Frequently you will find around 5 stripes on their body. Common Tidepool Sculpin colouring is grey or green, but their colour is not limited to that; you can find tidepool sculpins of almost every colour.
Habitat: Tidepool Sculpins are salt water fish that live in tidepools and in sheltered intertidal areas. They are usually found near rocks in the low-level of the tide pool. Tidepool Sculpins have been known to live in water as cold as 0.5C (33 F). Interestingly enough, Tidepool Sculpins are able to find their way back to their favourite tidepools following a high tide.
Food: Tidepool Sculpins eat small Invertebrates, isopods, amphipods, shrimp and worms. They can change the colouring of their bodies to blend in with their surroundings allowing them to ambush their prey. By surprising their prey and quickly chowing down, it is an effective way to hunt.
Predators: Tidepool Sculpins have a number of predators. Common predators of the Tidepool Sculpin are the Great Blue Heron (Ardea Herodias), larger fish and crabs but they are also likely eaten by other shore birds, river otters and foraging raccoons. Luckily for them, they were graced with speed and the ability to blend and hide allowing them to protect themselves from creatures who would like to eat them.
Life Cycle: Tidepool Sculpins generally live to be 5 years old. They are oviparous, meaning they lay eggs. The color of the eggs can vary depending on where they are laid. Typically they will be green or pink. It falls on the fins of the male tidepool sculpins to watch the eggs for the majority of the time.
