During a dive at McKenzie Bight I was surprised to see a fringed sculpin (Icelinus fimbriatus) resting beside a glassy tunicate! Through Danny Kent’s research at the Vancouver Aquarium it has been determined that the fringed sculpin has been depositing its eggs into glassy tunicates. This is an interesting situation as the fish eggs are protected within the tunicate from predation and are also well oxygenated.
Take a look at the original Vancouver Aquarium post on this topic:
The fringed sculpin can grow to 7.5 inches (19 cm) long, with a range from British Columbia to southern California.
