Sponges are animals with dense skeletons that are highly adapted to their environments, although it is easy to see why they may be mistaken for plants. All animals eat other organisms in order to gain building materials for the body. Sponges are the simplest of animals, and they may stand at the root of all complex animal life on Earth, including us humans. Sea urchins eat a variety of algae, mollusks, sponges, carrion, as well as starfish and sea urchins of smaller size.

The majority of sponges are filter feeders, which means they eat tiny particles of bacteria and phytoplankton they syphon out of the water. Hank introduces us to the "simplest" of the animals, complexity-wise: beginning with sponges (whose very inclusion in the list as "animals" has been called into question because they are so simple) and finishing with the most complex molluscs, octopuses and squid.

Sponges are found in a wide variety of colors, shapes, and sizes â and scientists believe that the colors of the sponge may act as a protection from the sunâs harmful UV rays. At least, most of them are. What can sponge cells do that other animals' cell cannot? But what was the evidence that makes the sponges an animal? Coral Reefs: Coral reefs are very important to the future of the planet Earth. Loggerhead and Ridley sea turtles are omnivorous and have jaws built for crushing food. Sponges (poriferans) are very simple animals that live permanently attached to a location in the water - they are sessile as adults. A number of sponge species are known to have a more carnivorous diet, eating small fish and crustaceans on the reefs. Sea sponges were the first animals on Earth, scientists discover. The feed of sea sponges What are spicules? The channels that the water flows through account for their hole-riddled structure, and is what makes their composition so useful. 4. tissues. Protein, To Eat, and Reproduce. They attach themselves permanently to an anchorage, and move sea water through their bodies, filtering out tiny organisms for food. 3. 2. They feed mainly on algae, although some species will eat corals and sponges. They are very common on Caribbean coral reefs, and come in all shapes, sizes and colors.

Sponges are omnivorous animals that obtain their nutrition from the food particles in the water. Some sponges contain photosynthesitic micro-organisms (like corals do) in their bodies. Calcareous sponge, any of a class (Calcarea) of sponges characterized by skeletons composed entirely of calcium carbonate spicules (needlelike structures). 3. They appear to be plants but are in fact invertebrate animals. They capture their prey just as they do with the organic particles: waiting for the tiny animals swimming in the ocean currents to be hooked into their pores and then wrapped and swallowed. Sponges are among the simplest of animals. They are primitive, sessile, mostly marine, waterdwelling filter feeders that pump water through their bodies to filter out particles of food matter.

A few species of sponge are carnivorous preying mainly on small crustaceans and other small animals. Each piece of sponge will last quite a long time. Sea sponges also grow on the coral reefs or near those places where they can access plenty of particles rich in nutrients. Some representatives of this species are known for the power to catch and eat a mantis cancer. The species of sea sponges living in waters with an inadequate supply of food prey on crustaceans and other small animals, hence they are referred to as the carnivorous sponges. Sponges are Sessile,Pore bearing, diploblastic(earlier stages) ANIMALS. These characteristic of the sponges had fooled early scientists of thinking that these creatures belong to the plant kingdom rather than in the animal kingdom. The cells of sponges are capable of differentiating into functional cell types, however, sponges lack the âtrueâ tissues, organs, and systems associated with more complex animals [2]. Hawksbill sea turtles are carnivorous and eat mainly sponges, tunicates, shrimp and squid. Nevertheless, sponges are quite successful. They filter water through their porous body for the food they eat. They are one of the most simple of all the multi-celled animals.

They feed on suspended organic matter in the water that is frequently too small for other filter feeders to access.
