Frogfish

Frogfish are some of the most bizarre looking fish in the ocean. They are a type of angler fish with amazing adaptations for camouflage. Their bodies are oddly shaped and they can change colors to blend in with their environment. Most frogfish mimic corals, sponges, seaweed, or rocks. This camouflage keeps predators from identifying them as food, and it keeps their food from identifying them as predators.

Frogfish spend most of their lives scooting along the bottom of the ocean. They lie motionless, resting on specially modified fins that act almost like legs.

Like most angler fish, frogfish have a very clever method of hunting prey. Instead of going out to find their food, they bring their food to them. Frogfish have a small growth on their heads that looks like a small worm or fish. They dangle this lure in front of their mouth, tricking other fish into thinking it is food.

The fish come close, thinking they will eat an easy meal. Instead they become the meal for the frogfish.


Frogfish are found in oceans throughout the world, and they take on a staggering variety of shapes and colors.

Coral

Coral reefs are home to millions of fish and some of the most abundant and beautiful life on our planet. Coral reefs also provide a barrier to protect land from erosion and they can even form entire islands. Much of the sand found on many tropical beaches is actually coral, ground up and refined.

Coral may look like brightly colored rocks but they are actually living creatures that secrete a hard exoskeleton where they live. Colonies of thousands of tiny creatures cling together to build a coral head. These coral heads build on each other to make an entire coral reef where a myriad of life can thrive.

Coral are actually related to jellyfish and sea anemones. They are very delicate and can only live in certain conditions. They need clear, shallow water to allow plenty of sunlight to reach them. They also need very warm temperatures to thrive. This is why most coral reefs are only found in the tropics. The reason they need so much sunlight is because they actually have algae living in their cells. The coral provides the algae with shelter and safety, and the algae provides coral with energy. Coral also feeds on floating animal materials that it snags in its outstretched tentacles.
