Unusual swimming mechanism in Calycopsis borchgrevinki (Hydrozoa)
Calycopsis borchgrevinki (Browne, 1910) from Antarctic waters was studied histologically. The entire bell is enclosed in a chitin-like skin, supported by chitin-like rods in the radial mesogleal fibres. In the tentacles a thick mesogloea is present without chitinous structures.

Summary: | Calycopsis borchgrevinki (Browne, 1910) from Antarctic waters was studied histologically. The entire bell is enclosed in a chitin-like skin, supported by chitin-like rods in the radial mesogleal fibres. In the tentacles a thick mesogloea is present without chitinous structures. The gonads are embedded in the stomach folds. It is postulated that these characters are adaptations to ecological conditions in Antarctic waters. |
