## Appearance

The Sponge is a diverse aquatic animal, often appearing as an irregularly shaped, porous mass. It can be brightly colored in yellows, reds, purples, or greens, and its textured surface is covered in tiny holes. Unlike plants, it has no leaves or roots, and unlike other animals, it lacks distinct organs or moving parts.

## Taxonomy

- **Kingdom:** Animalia
- **Phylum:** Arthropoda
- **Class:** Demospongiae
- **Family:** Crambeidae
- **Genus:** Crambe

## Interesting facts

- Some sponges create powerful natural chemicals to defend themselves from predators.
- Sponges are the oldest known animals, existing for over 600 million years!
- They don't have muscles, but they can slowly change their body shape over time.
- Thousands of tiny creatures make their homes and hideouts inside large sponge bodies.

## Special abilities

- **Super Sifter:** Sponge can filter huge amounts of water because of its porous body, helping them capture tiny food particles.
- **Regeneration Realm:** Sponge can regrow entire lost body parts from just a fragment, helping them recover from damage.
- **Hydro-Pump Power:** Sponge has specialized cells called choanocytes that create water currents, helping them draw in food and oxygen.

## Measurements & details

- **Length:** 1-200
- **Weight:** 0.01-50
- **Lifespan:** 1-1000
- **Filter Rate:** 10-1000

## Diet & Feeding

Sponges are tiny living filters, slurping up microscopic bits of food from ocean water.

- **Primary Foods:** plankton, bacteria, detritus, dissolved organic matter
- **Foraging Method:** Filter feeding

## Ecological connections

- **Symbiotic with:** Symbiotic Algae (*Symbiodinium microadriaticum*) — Algae live inside, providing food from sunlight.
- **Shelter:** Sponge Snapping Shrimp (*Synalpheus regalis*) — Shrimp find protection and food within sponge pores.
- **Eaten by:** Anna's Chromodoris (*Chromodoris annae*) — Colorful sea slugs graze on sponges for food.
- **Eaten by:** Spiny Sea Star (*Mithrodia bradleyi*) — Sea stars slowly consume sponge tissue.

## Safety

**Danger:** 1/5 · Very low

Sponges in the ocean are safe to observe but avoid touching them to protect their delicate structures.

## Frequently Asked Questions

### How to identify Sponge?

Look for fins, arms, tentacles, shells and body symmetry. Underwater light shifts colors, so structure and markings usually matter more than shade. Sea Creature Identifier: upload a photo and compare the visible details.

### How much does Sponge weigh?

0.01-50

### How long does Sponge live?

1-1000

### What does Sponge eat?

Sponges are tiny living filters, slurping up microscopic bits of food from ocean water.

### Where is Sponge usually found?

Marine

### How does Sponge hunt?

Filter feeding

### How much can Sponge filter in an hour?

10-1000
