Summary

Description

Lychaete battersii is a small filamentous green algae. It may reach up to 3 cm in height. It is a regularly branched, rather stiff species. The curved branches narrow from the base giving a spinous appearance. Growth predominently occurs between the base and the apex of the thallus. It is usually unattached, forming dark green masses.

Recorded distribution in Britain and Ireland

Currently known from a few locations around the British Isles and Ireland: Portland (Dorset), North Uist (Inverness-shire) and Northern Ireland.

Global distribution

Only recorded from the British Isles.

Habitat

Lychaete battersii is a shallow subtidal species often found loose-lying in sheltered habitats, occasionally tangled around Zostera plants and other algae.

Depth range

-

Identifying features

  • Dark green filamentous masses.
  • Curved, pointed branches.
  • Dominent growth in the middle of the thallus.
  • Rhizoids absent.
