Note: The polka dot black thing in the bottom left-hand corner of my pictures is my bag (token to demonstrate photo is taken by me). Also, my iPod is old so the photos aren’t high quality, but hopefully the organisms are still identifiable.

 

Here is an example of a parasitic symbiotic relationship. The cloud sponges eat floating plankton, except the galatheid crabs have a similar diet. They take advantage of this by eating the organisms that should have become the sponges’ food.

 

Hidden among the leaves is a golden poison frog. On it’s bright yellow skin is batrachotoxin, which can lead to heart failure on contact.

 

Next to the bag is a barely visible stingray. The colour of the stingray matches the colour of the sand, allowing it to camouflage into the environment.

 

In this picture, there are many biotic and abiotic factors. The rocks provide a surface for the white anemones and barnacles to attach to. All of the organisms are sea creatures, so the water is another contributing abiotic factor.

 

Here is a picture of a sturgeon. They are critically endangered, due to excessive fishing for their quality caviar.

 

This is a picture of a beluga. Over thousands of years, the beluga have adapted to a cold habitat. One of these adaptations is the absence of a dorsal fin. Without a dorsal fin, it is easier to swim under ice sheets and preserve body heat.
