Predicting Coral Gardens habitats in the Southwest coast of Portugal

Coral gardens are vulnerable and sensitive habitats protected by the OSPAR Commission. Knowledge on their distribution is essential to provide protection and integration in marine protected areas and also for marine spatial planning actions. In the southwest coast of Portugal deep water coral gardens (50-80m) are characterized by several gorgonians species such as Paramuricea clavata … Read more

Distribution of Deep-Sea Laminarians around three spanish Marine Protected Areas

Most marine protected areas (MPAs) have been declared marine extensions of protected terrestrial ecosystems. Therefore, these protected sites are around or beside coastal or island marine reserves, natural parks, etc. That means that most of the protected seabeds are normally shallow coastal areas usually no deeper than the infralittoral zone. Deep-sea laminarians extend down to … Read more

First records of Asbestopluma hypogea Vacelet and Boury-Esnault, 1996 (Porifera, Demospongiae Cladorhizidae) on seamounts and in bathyal settings of the Mediterranean Sea

The carnivorous sponge Asbestopluma hypogea, was known only from shallow submarine caves (-15 to -26 m) in the Western Mediterranean Sea and the Adriatic. Herein A. hypogea is reported from outside of caves, on seamounts in the Alboran Sea (-167 m), off the Balearics (-100 m) and north off Sicily (-660 m), and along steep … Read more

A giant foraminifer that converges to the feeding strategy of carnivorous sponges: Spiculosiphon oceana sp. nov. (Foraminifera, Astrorhizida)

Agglutinated foraminifera make a relatively diverse group of organisms, which is taxonomically defined as a subclass (Textulariia) and comprises four orders. The orders are based upon gross morphology, wall structure, and cement composition (Kaminski 2004). The cement that binds the test together may be organic (as in the Astrorhizida), calcareous and canaliculate (as in the … Read more

Unexpected records of ‘deep-sea’ carnivorous sponges Asbestopluma hypogea in the shallow NE Atlantic shed light on new conservation issues

  Marine cave communities have been a continued source of ecological surprises, among other things because of their close ecological and evolutionary ties with the deep sea. The discovery of cladorhizid sponges, the deepest occurring poriferan family, in shallow Mediterranean caves in the 1990s was one such surprise, leading to the generally accepted hypothesis that … Read more
