Oscarella Lobularis
''Oscarella lobularis'' is a species of sponge in the order Homosclerophorida. It is native to the northeastern Atlantic Ocean and the Mediterranean Sea, where it forms encrusting colonies on rocks and other hard surfaces. Description ''Oscarella lobularis'' is an encrusting sponge that forms a thick layer of soft, gelatinous consistency with a velvety surface, on rocks, stones and large seaweeds. Colonies are up to wide and thick, with an irregularly lobed surface. The sides of the nodular lobes have a scattering of ostia through which water passes into the sponge, and at the top of each, a single round osculum up to in diameter, through which water exits. This sponge has neither spicules nor spongin fibres in its tissues. It is usually some shade of yellow or brown but can occasionally be red, violet, green or blue, often with a cream-coloured base layer. Ecology Like other sponges, ''Oscarella lobularis'' is a filter feeder. Water is drawn into the interior of the sponge t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oscarella Tuberculata
''Oscarella tuberculata'' is a species of sponge in the order Homosclerophorida. It is endemic to the Mediterranean Sea, where it forms encrusting colonies on rocks and other hard surfaces. Description ''Oscarella tuberculata'' is a thickly encrusting sponge forming small patches up to in diameter. The tissue contains no spongin or spicules but is firm to the touch, with a cartilage-like consistency. The surface is granular or wrinkled, with Irregular lobes and bulges, and small tubular structures emerging, some bearing osculae. This sponge is fairly uniform in colour, usually being yellowish-green, sometimes with a bluish tinge; occasionally, different parts of the colony differ in colour. Distribution ''Oscarella tuberculata'' occurs in the Mediterranean Sea at depths of between about , on rocky substrates. It often grows in caves and under overhangs. Biology ''Oscarella tuberculata'' is a filter feeder. Water is drawn into the interior of the sponge through minute pores cal ...
