![]() The interface of the TL and AL, where tubercles fit into depressions of the lower surface of the AL, represent tenon and mortise or dovetail joints, making the spicules more stiff/strong and thus less prone to breaking in the lower part. The new layer type that we called the Ripple Mark Layer (RML) was noted, as well as narrow spikes on the AL ridges, both structures not reported earlier. The apparent perforated and non-perforated bands of the AL are an optical artefact. ![]() The TL was found to display positive structures (tubercles), not depressions, as earlier suggested. The AL differs significantly from the PG and TL in being granular and porous in structure. The TL, which is composed of several thinner layers, is formed by a progressive folding of its surface but its microstructure is the same as in the PG layer (glassy silica). PG, TL and AL can substitute for each other along the surface of the spicule, but equally they are superimposed in older parts of the spicules, with AL being the most external and occurring only in the lower part of the spicules and TL being intermediate between AL and PG. Young, immature spicules display only plain glassy silica layers which dominate the spicule volume. plain glassy layer (PG), tuberculate layer (TL) and annular layer (AL), and an axial cylinder (AC) characterize adult spicules. Three morphologically/structurally different silica layers i.e. In this work, we present the results of detailed examinations with transmitted light and epifluorescence microscopy, SEM, solid state NMR analysis, FTIR and X-ray analysis and staining of Monorhaphis chuni basal spicules of different sizes, collected from a number of deep sea locations, to better understand its structure and function. Thorough examination of new material of this basal spicule has revealed numerous inconsistencies between our observations and earlier descriptions. Due to its large size many researchers have described its structure and properties and have proposed it as a model of hexactinellid spicule development. Generally, sponge spicules are of scales from micrometers to centimeters. We’re just trying to be funny and this has got nothing to do with the show.”ĬNN has reached out to Nickelodeon for comment.A basal spicule of the hexactinellid sponge Monorhaphis chuni may reach up to 3 m in length and 10 mm in diameter, an extreme case of large spicule size. “It doesn’t have anything to do with what we’re trying to do,” People magazine reported Hillenburg as saying. ![]() Hillenburg died in 2018 at the age of 57 due to complications resulting from amyotrophic lateral sclerosis, more commonly known as ALS. #SpongeBobIsGay started trending as many decided the tweet was confirmation of the character’s sexuality.ĭue in part to his close relationship with best friend Patrick Star, the internet had long ago decided that SpongeBob was indeed gay.īut the show’s creator, Stephen Hillenburg, dismissed speculation about the characters’ relationship and sexuality in 2005. “Celebrating #Pride with the LGBTQ+ community and their allies this month and every month,” the tweet reads.

The network included a photo of the beloved animated character in a recent tweet celebrating Pride Month. There has long been debate about the sexuality of SpongeBob Squarepants and some are taking a Nickelodeon tweet as his coming out.
