Euplectella is a genus of deep-sea glass sponges in the class Hexactinellida, commonly known as the “Venus’ flower basket.” These sponges have a delicate, cylindrical body made of a lattice of silica spicules, giving them a glass-like appearance. They live anchored in soft sediments on the ocean floor and feed by filtering microscopic particles from […]
Leucila Leucila is a genus of small marine sponges that belongs to the class Calcarea, a group characterized by spicules made of calcium carbonate. These sponges are typically found in shallow coastal waters, where they attach to rocks, shells, or other submerged surfaces. It feeds by filtering microscopic particles and organic matter from seawater, helping
Grantia Grantia is a genus of small marine sponges belonging to the class Calcarea, which are characterized by spicules made of calcium carbonate. These sponges are usually found in shallow coastal waters attached to hard surfaces such as rocks and shells. Grantia has a simple tubular body structure with numerous pores that allow water to
Sycon or Scypha Sycon is a genus of small marine sponges that belongs to the class Calcarea, whose members possess calcium carbonate spicules forming their skeletal framework. These sponges are commonly found in shallow coastal waters attached to hard surfaces such as rocks or shells. Sycon has a cylindrical body with a system of pores
Clathrina or Olynthus Clathrina and Olynthus are simple marine sponges belonging to the class Calcarea, characterized by skeletons made of calcium carbonate spicules. Clathrina typically forms delicate, branching or tube-like colonies attached to hard surfaces in shallow coastal waters. It has a very simple body organization in which water flows through small openings directly into
Leucosolenia Leucosolenia is a genus of simple calcareous sponges belonging to the class Calcarea. These small, tube-shaped sponges are usually found in shallow marine waters attached to rocks, shells, or other submerged surfaces. Their bodies contain calcium carbonate spicules and a basic canal system that allows water to flow through for filter feeding on microscopic
Phylum Porifera Phylum Porifera, commonly known as sponges, might seem unassuming at first glance—decorating aquariums, inhabiting the silence of ocean floors—but beneath that simplicity lies a group of animals that changed the course of life’s evolution and are central to unlocking the mysteries of multicellularity. In a world rushing toward complexity, these quiet, ancient beings
