Murici Ecological Station an average of . The dominant vegetation is dense rainforest in the Atlantic Forest biome. In the best preserved areas, mostly at the higher elevations, the forest forms a fairly uniform closed canopy up to high that provides shade and retains moisture. Tree species include murici ("Byrsonima sericea"), "Schefflera morototoni", "Parkia pendula", "Tabebuia" species, "Pseudobombax" species, "Bowdichia virgilioides", "Tapirira guianensis", "Handroanthus impetiginosus" and "Protium" species. The understory contains seedlings of trees, palms such as "Euterpe catinga", and many lianas and epiphytes, such as "Araceae", "Orchidaceae" ("dimerandra" species, "Dichaea" species, "Rodriguezia" species, "Cattleya labiata", "Pleurothallis" species, "Epidendrum" species, "Oncidium" species and
Portia labiata the prey is thoroughly stuck. When an insect stuck in a web owned by "P. labiata", "P. schultzi" or any regional variant of "P. fimbriata", and next to a web spider's web, the web spider sometimes enters the "Portia"′s web, and the "Portia" pursues and catches the web spider. When catching an insect outside a web, a "Portia" sometimes lunges and sometimes uses a "pick up", in which it moves its fangs slowly into contact with the prey. In some pick ups, "Portia" first slowly uses its forelegs to manipulate the prey before biting. "P. labiata" and "P. schultzi" also
