Hombergi spawn.St Abbs.
Its not Hombergi slug spawn as I see loads of this at St Abbs and its flat and only 1-2 cm big.
The Large egg mass is BIG. 10cm . Only thing i can think of is a Sea Hare or a big free swimming slug.
Speaking of that some guys have reported sightings of Spanish Dancers off Dunbar and that aint far off St Abbs.
