Biology. Halopteris catharina has been collected frequently from other hydroids and algae, sponges, corals, worm tubes and ascidians ( Ramil & Vervoort 1992; Ansín Agís et al. 2001; Gravili et al. 2013). The gonothecae have been found in February and from April to September ( Ansín Agís et al. 2001).
In our material, some colonies were found growing on sponges, other hydroid species, the scleractinians L. pertusa and M. oculata and the bivalve A. excavata .
Distribution. This species has a wide distribution on both sides of the Atlantic Ocean, from the Arctic to the southern-boreal regions, including the Mediterranean Sea ( Ramil & Vervoort 1992). For a detailed distribution, see Ansín Agís et al. (2001). In West Africa, H. catharina was collected from Morocco ( Ramil & Vervoort 1992), Mauritania ( Gil & Ramil 2017a) and Cape Verde Archipelago ( Ansín Agís et al. 2001; Vervoort 2006). Its bathymetric range stretches from 1 to 627 m ( Ansín Agís et al. 2001; Gil & Ramil 2017a).
The material studied by us was collected from depths of 405 to 642 m.
Remarks. The plumose aspect of the colony with opposed hydrocladia and presence of a supplementary pair of lateral nematothecae helped in accurate identification of this species.
