Beroe cucumis is a medium-sized, sack-shaped comb jelly. It may reach up to 15 cm in length. It is completely transparent in colour. It swims with eight longitudinal combs that give the comb jellies (ctenophores) their characteristic shimmering appearance. These combs consist of plates of transverse rows of hairs that beat in waves downwards, which produces the shimmering effect. These plates are phosphorescent at night.
Recorded distribution in Britain and IrelandRecorded off the west and northern coasts of Scotland and the coasts of Wales. Possibly under recorded.
HabitatThe comb jelly Beroe cucumis is a pelagic species.
- Transparent sack-shaped body up to 15 cm in length.
- Radially symmetrical with secondary bilateral symmetry.
- Eight longitudinal rows of combs of equal length.
- No tentacles.
- Branched gastrovascular system unlike Beroe gracilis.
Beroe cucumis is carnivorous and feeds on other comb jellies, particularly Bolinopsis infundibulum. Instead of sticky tentacles or large oral lobes, the large mouth is used to engulf prey whole (Greve, 1975).
