Latest Hexactinellid Stories
Sponges are usually considered to be the oldest living animals, having evolved before all other groups. The simplicity of their body structure and tissue organization has for many years made them candidates for the ancestral group of animals, and they have long been regarded as our best illustration of what the earliest animals would have looked like. This has been supported by genetic analyses, which suggest that sponges branched from other animals a very long time ago, deep in the...

The study, published in Current Biology, reports on a surprisingly prolific community of glass sponges colonizing an area formerly covered by permanent ice - surprising because the sponges live long, slow lives that can extend up to 10,000...
Venus’ Flower Basket (Euplectella aspergillum) is a species of hexactinellid sponge found in the deep ocean. It is found with a male and female shrimp living inside it, which spend their lives living in just one sponge basket. Because of this, Asian cultures use the dead, dried sponge as a wedding present to signify the symbiotic relationship of the sponge and shrimp.
