Anything calcareous sponges and humans have in common? Both use carbonic anhydrase for biocalcite production, acting as building block for calcareous sponge spicules and bioseeds during mammalian hydroxyapatite formation. Purse sponge from the N Adriatic Sea. #spongeThursday

Some glass sponges may be the oldest animals on Earth. Individuals of Monorhaphis chuni are estimated at over 11,000 years old, and they build a single skeletal spike up to 3m long, the largest natural glass structure any animal makes. 🧪 #SpongeThursday #HowToBuildAGiant #marinelife

Especially on the subaqua branches of the bankside Willows, & sheet pilings in their shade, spectacular growths of Freshwater Sponges (Spongillidae). Here in the lower River Little Ouse, where the flow is slow, it needs these finger like growths to 📈 surface area for filter feeding. #SpongeThursday
