This islet is located at a distance of approximately 65 metres from the south-eastern coast of Qala. It forms part of the geology of the complex that includes the island of Comino and the upper Qala regions. The islet measures approximately 4,800m² and supports two distinct vegetation communities. The lower region is dominated by the Shrubby Glasswort (Arthrocnemum macrostachyum), with the Olive-leaved Bindweed (Convolvulus oleifolius) being more dominant towards the central region of the islet. Other important species present in this area include the Maltese Sea-Lavender (Limonium melitensis) and the Sea Carrot (Daucus rupestris), the latter a sub-endemic to the Maltese Islands, Lampedusa, Lampione and Panarea.

The upper region of the islet is colonized by Esparto grass (Lygeum spartum), the Olive-leaved Bindweed (Convolvulus oleifolius), the Sea Carrot (Daucus rupestris), the Pyramidal Orchid (Anacamptis urvilleana), the Maltese Leek (Allium melitense), the Carline Thistle (Carlina involucrata) and two stunted Lentisks (Pistacia lentiscus).

The fauna on this islet includes an isolated population of the endemic Wall Lizard (Podarcis filfolensis) and a morph of the endemic Door Snail (Muticaria macrostama forma oscitans). The faunal species are reproductively isolated from the mainland populations and thus have the potential of developing specific traits.

MEPA scheduled Il-Gebla tal-Halfa as a Level 1 Site of Scientific Importance (ecology), Level 2 Site of Scientific Importance (geomorphology), and a Level 2 Area of Ecological Importance as per Government Notice No. 827/02 in the Government Gazette dated 20 September 2002.
