Their Habitat• Sea Sponges grow in all
oceans in the world no matter what temperatures.
• They can be found hundreds of meters under sea, but mostly are found in 5-50 meters deep.
• Most sponges’ optimal pH is around 6.5 because the pH value of the sponge cellular fluid is 6.5.
• Some sponges can live in the outstanding temperatures and pressure.

Physical Features• Sponges come in different striking
colors, bright red, purple, yellow, and brown, etc.
• These colors are toxic as well may help them defend from sponge eating invertebrates and some fishes.
• Sponges often have skeleton, which protect and give refuge to small invertebrates .
• Sponges have no tissues or organs, they are just constructed with layers of cells even without nervous system.
• Inside the sponge, the special cells circulate seawater through small pores and absorb planktons and small sea organisms.

Fun Facts

that sponges were thought to be a plant.
• Sponges can contain 16,000 other animals
inside of it.• One of the largest
sponges ever was almost 10 feet wide.
• When a part of a sponge breaks off, the broken part will form a new
sponge. http://images.starpulse.com/Photos/Previews/SpongeBob-SquarePants-p35.jpg
