Examples of Shark Adaptations
They have streamlined bodies to help them swim fast and gills that take oxygen out of the water so they can breathe. One amazing shark adaptation is called the Ampullae of Lorenzini. The Ampullae of Lorenzini are small holes or pores found on sharks’ noses. Each pore has sensory organs inside which allow sharks to sense electric fields put off by other fish and animals. This helps a shark find prey even if that prey animal is still and quiet.
Examples of Jellyfish Adaptations
Medusa jelly can shrink in size when there isn’t enough food.
Sea stars don’t have a lot of ways to protect themselves so their adaptation for survival is being able to grow back their arms if they lose one. Their arms are called rays, and the sea star knows how many they are supposed
to have. Some types of sea stars can even grow their entire body back from just one ray.
Types of Stingray Adaptations
Stingrays will cover their body in sand to help them hide. They have eyes on top of their bodies so they can see when they are resting or hiding in the sand.
Dolphin Adaptations
Dolphins are mammals and need air to breathe. They breathe through an adaptation called a blowhole. The blowhole is on the top of their head so they can rest at the surface of the water and still be aware of possible predators.
