The pH of water must match that of seawater (pH 7.8–8.4) in order for sponge production to be maximized. Sponges are sensitive to temperature, and extreme fluctuations in ambient temperature can negatively affect the health of sea sponges. High temperatures lead to crashes in sponge cultures.
Chondrocladia concrescens (formerly Cladorhiza concrescens) is a species of deep-sea carnivorous sponge in the family Cladorhizidae. It is commonly known as the "ping pong tree sponge" due to its distinctive tree-like shape with multiple branches. The species is found in the eastern Pacific Ocean and can grow up to one meter in height.
These sponges gained media attention when a new species, a gourd-shaped carnivorous sponge, was featured in reports of finds off the coast of Antarctica.The new Chondrocladia was one of 76 [citation needed] sponge species identified in the seas off Antarctica by the Antarctic Benthic Deep-Sea Biodiversity Project (ANDEEP) between 2002 and 2005, conducted aboard the German research vessel ...
Amphimedon compressa can grow to a length of 40 cm (16 in) and a diameter of 4 cm (1.6 in), but it is usually smaller in shallow water. The tree-like curved branches grow from a basal encrusting mass, but very occasionally this sponge grows as a small, unbranched, flattened hemisphere. Many small osculi are found on the branches.
The study’s authors collected sponges from waters at least 100 feet deep off Puerto Rico and near the island of St. Croix, analyzed their skeletons’ chemical composition, charted their ...
Callyspongia crassa, commonly known as prickly tube-sponge, is a species of sponge found from the Red Sea to the Seychelles.Its wide flexible brown tube with exterior protuberances can appear as a single tube or as clusters of tubes and can reach up to 50 centimeters (20 inches) in size.

Chondrocladia lyra, also known as the lyre sponge or harp sponge, is a species of carnivorous deep-sea sponge first discovered off the Californian coast living at depths of 10,800–11,500 feet (3,300–3,500 m) by Welton L. Lee, Henry M Reiswig, William C. Austin, and Lonny Lundsten from the Monterey Bay Aquarium Research Institute (MBARI).
