Project Description

A very unusual pale giant California sea cucumber (Apostichopus californicus) was noticed on a dive at Oak Leaf, near Nanoose Bay on Vancouver Island.  This is only the second one I’ve observed without colours present, with the first being spotting at Kelvin Grove, north of Vancouver, over 20 years ago.  The giant California sea cucumber can grow to around 20 inches (50 cm) long, and has large stiff conical spikes or papillae.  This species of sea cucumber is often solid red or reddish-brown.  There are also many variable colour combinations with mottled patterns of red, brown, white and yellow.  The giant California sea cucumber resides on rocks and soft substrates with a range from central Alaska to northern Mexico.
