Found in a tide pool on a piece of ulva during low tide at Eagle Bay.
Its body is elongated and has cone shaped papillae (projections) of varying sizes along its length, with 20 short busy tentacles at one end. They vary a lot in colour, but they are often dark red, reddish brown, mottled brown or yellowish brown, but some can be lighter or even white. The underside tends to be lighter.
It is found from the low intertidal zone to a depth of 250 m. They are most abundant in areas with moderate current with cobbles, boulders or bedrock to squish between.
(It is the TINIEST baby GIANT sea cuke I have ever seen, and it is my absolute favourite thing ever. I love it.)
