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. Symbiotic bacteria that normally inhabit sea sponges start reproducing at an unsustainable rate when ambient temperature of the water increases by a few degrees.
Hexactinellid sponges require a hard substrate, and do not anchor to muddy or sandy sea floors. [6] They are found only where sedimentation rates are low, dissolved silica is high (43–75 μM), and bottom currents are between 0.15 and 0.30 m/s. [5] Dissolved oxygen is low (64–152 μM), and temperatures are a cool 5.5-7.3 °C at the reefs. [5]

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.
Aplysina fistularis (A. fistularis), also known as the yellow tube sponge or yellow sponge, [1] is a species of sea sponge in the order Verongiida. [2] Aplysina fistularis is a golden or orange-brown color with a conulose surface. The animal is abundant in the Caribbean, where it is commonly found in reefs of open water areas. [1]
Callyspongia plicifera, the azure vase sponge, is a species of sea sponge belonging to the family Callyspongiidae. It is native to the Bahamas where it is found at a depth of 31.5-44.2 m. It was first described in 1814 by Jean-Baptiste Lamarck. [1]
