Plate 10 of Hexactinellida, a sepia photographic plate showing 29 numbered microscope images of glass sponge spicules from Caulophacus schulzei. Thin rod-shaped spicules with knobbed or roughened tips appear at top left. Large spicules with long tufted rays rising from a cross-shaped base, resembling broom heads, fill the left and lower edges. Close-ups show spiny branching ray junctions. Star-shaped spicules with feathery tufts at each arm tip appear in the center, and dense tangled skeletal networks and clusters of star-like spicules occupy the right side.

Illustration titled "HEXACTINELLIDA" from a 1910-15 Cambridge publication, showing detailed drawings of sponge spicules. The image features multiple numbered, magnified views of glass-like sponge skeletal elements, including star-shaped and three-pronged forms with smooth, curved arms. Small inset photographs highlight the intricate, mesh-like network formed by these spicules in living sponges. The plate focuses on two species: Holascella euonyx (figures 1-24) and Farrea occa var. scutella (figures 25-29), revealing structural details such as the shape and arrangement of individual spicules essential for sponge rigidity and filtering functions.

Let’s just say that deploying rolling vacuums the size of Sherman tanks a mile under water to rip through habitats that have evolved over millions of years and that we barely understand is the definition of epic ecological disaster.

Historical scientific illustration plate titled "Hexactinellida" from 1910-15, displaying various views and details of glass sponges. The plate features labeled numbered images showing sponge structures, including circular spicule formations (figures 1-4), sponges with fibrous textures (figures 5 and 6), and close-up views of spicule cross-sections and arrangements (figures 8-26). Among these is a detailed photograph of a sponge specimen (figure 14) set on small pebbles. The drawings highlight the intricate skeletal framework of these siliceous sponges, emphasizing their star-like spicules and porous body shapes. The plate is arranged systematically to provide a comprehensive overview of sponge morphology and taxonomy within Hexactinellida.

Illustration titled "The sponges," showing detailed scientific drawings of the sponge species Hyalonema (Phialonema) brevancora. The plate features various numbered close-up views of sponge skeletal structures, including long, needle-like spicules, branching skeletal frameworks, and microscopic elements. The drawings highlight the intricate internal morphology and spicule arrangements typical of the Hexactinellida class. Each element is carefully labeled to demonstrate the sponge's complex anatomy, with both macroscopic and microscopic details emphasized. The page is a historical scientific print from Cambridge, dated 1910-15, documenting sponge morphology for museum reference.

Historical scientific illustration titled "The sponges," showing detailed black-and-white drawings of various sponge forms and their skeletal structures. The image features three main rounded, porous sponge bodies with textured surfaces, labeled 1, 12, 13, and 14, alongside elongated and star-shaped skeletal elements labeled 2 through 11. The sponges exhibit natural rough textures, and the skeletal parts display intricate branching and radiating patterns characteristic of Hexactinellida sponges. The illustration is dated 1910-15 and serves as a visual study of Hyalonema agassizii sponge species and their structural diversity.

Biological optical fibers?

Hexactinellida or 'Glass sponges' produce intricate transparent structures with optical capabilities similar to optical fibers, but using a wild ambient-temp process instead of requiring ultra-pure 2000°C conditions.
