Sponge Sponges are very slow-moving animals that are found across the sea floor. Although many sponges actually move less than a millimetre a day, some adult sponges are actually sessile, which means that they are fixed onto something and do not move at all.

Sponges are similar to other animals in that they are multicellular, heterotrophic, lack cell walls and produce sperm cells. Unlike other animals, they lack true tissues and organ

Light can limit sponge survival in a given habitat. Littoral-dwelling sponges generally develop in caves, on shadowed walls, or under small shelters such as those provided by crevices. Some species, mainly in the tropics, however, are covered by a metre or less of water and thus are exposed to considerable irradiation from the sun.

Habitat (Where they live, adaptations) Sponges can be found in almost all water habitats. Although most reside in marine bodies of water, up to 150 different species of sponges have adapted to freshwater climates. Many sponges contain a toxic substance to discourage predators and so other marine animals protect themselves by attatching a sponge ...

Sponges (Porifera) are a group of animals that includes about 10,000 living species. Members of this group include glass sponges, demosponges, and calcareous sponges. Adult sponges are sessile animals that live attached to hard rocky surfaces, shells, or submerged objects. The larvae are ciliated, free-swimming creatures.

2. Habitat and Range. The distribution of sea sponges is worldwide, and they live in the oceans from polar to tropic regions. Most of them live in clear water as the sediments in unclear water can latch onto the sea sponge when they stir up due to currents or waves, making it harder for them to feed.

Sponges (porifera) are some of the simplest animals in the ocean. With no tissues or organs, they're simply collections of cells arranged in various structures that capture nutrients passing through their pores. At least, most of them are. Carnivorous sponges can catch live food rather than just eat whatever ...

Distribution, habitat, and climate needs. The giant barrel sponge is common on reefs throughout the Caribbean Sea, the Bahamas, Bermuda and the reefs and hard-bottom areas of Florida and the Gulf of Mexico. In terms of benthic surface coverage, it is the second most abundant sponge on reefs in the Caribbean region.

When you look at a sponge, the word "animal" might not be the first that comes to mind, but sea sponges are animals. There are over 6,000 species of sponges; most live in the marine environment, although there are also freshwater sponges. Natural sponges have been used by humans to clean and bathe with for at least 3,000 years.
