If a sponge contains spicules along with organic compounds, the likelihood of those sponges being consumed by spongivores decrease. [10] Sponges have also developed aposematism to help avoid predation. Spongivores have learned four things about sponges aposematism and they are as follows: If it is poison some predators will not eat it
The term sponge derives from the Ancient Greek word σπόγγος spóngos. [9] The scientific name Porifera is a neuter plural of the Modern Latin term porifer, which comes from the roots porus meaning "pore, opening", and -fer meaning "bearing or carrying".
Hexactinellid sponges are sponges with a skeleton made of four- and/or six-pointed siliceous spicules, often referred to as glass sponges. They are usually classified along with other sponges in the phylum Porifera , but some researchers consider them sufficiently distinct to deserve their own phylum, Symplasma .
A rare OCD disorder causes her enjoy eating substances without any nutritional value.
They use their mouthparts to parasitize Spongillidae freshwater sponges (e.g. of the genus Spongilla, hence the name "spongillaflies") and Phylactolaemata freshwater bryozoans by stinging into the host animals' body and sucking out cell contents. The antennae are stouter than they look and are used to aid in locomotion.
Callyspongia (Cladochalina) aculeata, commonly known as the branching vase sponge is a species of sea sponge in the family Callyspongiidae. [1] Poriferans are typically characterized by ostia, pores that filter out plankton, with an osculum as the opening which water leaves through, and choanocytes trap food particles.
When animals eat seeds (seed predation or granivory) or eggs (egg predation), they are consuming entire living organisms, which by definition makes them predators. [6] [7] [8] Scavengers, organisms that only eat organisms found already dead, are not predators, but many predators such as the jackal and the hyena scavenge when the opportunity arises.
