This whirlpool worm is around 5 cm long and goes in search of food at nightfall. search for food at nightfall, i.e. it preys on a variety of different invertebrates. different invertebrates.
About the coloration of the worm: The edge of the whirlpool worm is yellow, followed by a broad, dark edge stripe and then a light, cream-colored then a light, cream-colored stripe and in the middle a narrow white central stripe, white central stripe.
It may be confused with Jebb's whirlpool worm (Pseudoceros jebborum), which has a very similar color pattern. has a very similar color pattern. The visual separation of the two species is extremely difficult.
The central pale band of both species can be covered by caramel-colored mucus, so that color, which is often associated with Jebborum is not a reliable distinguishing feature of the two species.
In Pseudoceros paralaticlavus the central band is narrow, about 1/4 to 1/3
of the worm width, measured while crawling. In Pseudoceros jebborum, the central band is wider, about 1/2 to 3/4 of the worm width, measured when crawling.
The final size of both species, 70 mm in Pseudoceros paralaticlavus and only 50 mm in Pseudoceros jebborum, provides a further aid to differentiation. This means that Pseudoceros paralaticlavus is slightly larger.
