Halisarca [Halisarca]

Description

Halisarca is the sole genus within the family Halisarcidae, known for its unique characteristics among demosponges. These sponges are characterized by their soft, gelatinous consistency, lacking the typical skeletal structure found in other sponges. They do not possess spicules or spongin fibers, which are common in the skeletal framework of most sponges. Instead, Halisarca species have a skeleton made of a network of collagenous fibers, giving them a distinctive, slimy feel. They are commonly found in shallow marine environments, attached to rocks or other substrates. The genus is notable for its simple, yet efficient, filtration system used for feeding, and it plays a significant role in the ecosystem by processing organic matter in the water.
