Tectitethya crypta is a species of demosponge belonging to the familyTethyidae.[1] Its classified family is characterized by fourteen different known genera, one of them being Tectitethya.[2] It is a massive, shallow-water sponge found in the Caribbean Sea.[3][4] This sponge was first discovered by Werner Bergmann in 1945 and later classified by de Laubenfels in 1949. It is located in reef areas situated on softer substrates such as sand or mud.[5][6] Oftentimes, it is covered in sand and algae.[3][4] This results in an appearance that is cream colored/ gray colored; however, when the animal is washed free of its sediment coverings, its body plan appears more green and gray. It's characterized with ostia peaking out of its body cavity, with the ability to abruptly open or close, changing its desired water flow rate through its mesohyl.
This sponge is widely known for its contributions to the field of medicine as a source for potent nucleoside analogues used in treating H.I.V, Acute Myeloid Leukemia, pancreatic cancer, Ebola, and others. The nucleosidesspongothymidine and spongouridine were isolated from this sponge, providing the basis for anti-viral drugs and anti-cancer drugs.[3][4]Vidarabine, an antiviral drug, was derived from these compounds.[7] The discovery of these nucleosides also led to the development of cytarabine for clinical use in the treatment of leukemia and lymphoma.[8]Gemcitabine, a fluorinated derivative of cytarabine, is used to treat pancreatic, breast, bladder, and non-small-cell lung cancer.[8] Holding such valuable compounds, free-living within the animal, T. crypta has shaped the present and future world of medicine.
