8 FACTS ABOUT SPOTTED EAGLE RAYS

First, look at these facts about spotted eagle rays.

1. Spotted eagle rays are easy to recognize by their dark blue or black bodies covered in white spots. The wide pectoral fins that resemble wings give them a bird-like appearance as they “fly” through the water.
2. They have very long tails, sometimes several times the length of their body, and some species have venomous spines near the base of the tail for defense.
3. Spotted eagle rays are found in tropical and warm temperate waters around the world, often near coral reefs, bays, and coastal areas.
4. They love to eat mollusks, crustaceans, and small fish, they use flattened teeth to crush shells. Their snouts are pointed and help them dig in the sand for food.
5. These rays can grow up to 10 feet across and weigh over 500 pounds, though most are smaller.
6. While sometimes they can be seen alone, spotted eagle rays are often spotted in groups, especially during migrations or feeding times.
7. Like other rays, they breathe through spiracles, small openings located behind their eyes, allowing them to take in water even when resting on the sea floor.
8. Spotted eagle rays are ovoviviparous, meaning the embryos develop inside eggs that stay inside the mother until they are ready to hatch. She gives birth to live young, typically 1–4 pups at a time.

Whether you’re sculpting sea turtles, painting coral reefs, or sketching jellyfish, your teen will gain a deeper appreciation for the ocean while developing their artistic voice.

SPOTTED EAGLE RAY WATERCOLOR TUTORIAL

You will need:

• Watercolor paper
• Watercolor paints
• Paintbrushes
• Pencil
• water
• Artist tape/washi tape
• Masking fluid
• Fine tipped black pen

Tape off the edges of your watercolor paper with artist tape or other low tack tape.

This step is not necessary but I love the clean look it gives the page and also the border makes the painting pop.

Start by sketching a large loose diamond shape.

Erase each of the corners and round off the two on sides, making it a little flowy for the tip of the fins.

EAGLE RAY WATERCOLOR TUTORIAL

At the top- round the corner and give it a nose like this.

For the back end draw a W inside a W shape on the bottom corner.

Add a long slim tail.

Erase your lines so they are very faint and won’t show through your painting.

Use the tip of a masking fluid pen or brush. And create spots all over the back of your eagle ray.

Allow to dry.

While the masking fluid is drying you can paint the water. Dab 2-3 shades of blue all the way around on the remaining white of the watercolor paper.

Darken it in areas and use a paper towel to absorb some of the paint to create a more complex water so it is not just flat.

Use a smaller brush to outline inside the edges of your ray with a dark gray, you can use a bigger brush to fill it in if you like.

Allow the ray to dry, then remove the masking fluid gently with your finger or a soft eraser to reveal the spots underneath.

You can leave your painting as is if you wish but I like to take a fine black pen and outline the ray to define it a bit more.

Don’t forget to add in the eyes as well.

Peel off the tape all the way around, then you will have a clean, satisfying border.
