What are the tube like jelly things in the water?

Question

Just curious, I have a photo but can’t upload it here. What are the piles of these little guys? They have at least one open end, pearly color with speckles and are everywhere in groups of hundreds.

Answer

The "tube-like jelly things" you're describing sound like marine organisms known as sea sponges, or possibly colonial jellyfish such as Portuguese man o' war or by-the-wind sailor (Velella velella). Based on your description of them being pearly, speckled, and appearing in large groups, they could belong to one of these species. Here are a few possibilities:

Sea Sponges: These are simple, soft-bodied animals that filter water for food. Sponges are often seen in shallow waters and can appear in clusters. Their tubes can vary in size, and they often have a speckled or textured appearance, though they’re typically not transparent. You might see the open ends of the tubes, which are part of their body structure.
Velella Velella (By-the-wind sailor): These are colonial jellyfish with a transparent, blue or purple body. They can often be found in large groups washed up on beaches or floating in the water. They have a sail-like structure that helps them drift with the wind, and their tentacles can be very tiny and delicate.
Portuguese Man o’ War: Though similar in appearance to jellyfish, these are colonial animals made up of several smaller, specialized creatures working together. They can appear as balloon-like floats on the surface of the water with long, trailing tentacles that can be quite dangerous if touched. Their bodies often have a speckled appearance in the right lighting.

Since you mentioned the presence of hundreds of them in groups, the most likely candidate could be the Velella velella, as they often appear in large clusters, especially after being pushed by the wind. They are harmless but can be intriguing to observe.

Note: It's always a good idea to avoid touching these creatures, especially Portuguese man o' war, as their tentacles can deliver a painful sting. Enjoy observing, but take care not to disturb them!
