Nematocysts are the stinging cells found in the tentacles of jellies and anemones. When provoked the stinging cell ejects a barbed thread that contains a toxin to stun (or kill) the enemy. The barbed thread is disregarded and a new one regenerates.
Here is a creative video explaining how jellies sting from jellyfishart.com. Enjoy!

NO! Not at all. Laughing gulls, or Larus atricilla, are quite aggressive. These birds travel up and down the coasts and never have to stray far inland. They are extremely confident and spend their days foraging food from overly-relaxed beach goers. They will easily push larger birds, for instance, a pelican, right out of the […]

From their diet. They eat foods high in beta carotene, mostly shrimp and algae. They also will eat mollusks (clams or snails) or crustaceans (crabs). They gather their food by gulping water with their beak and then straining the water and eating the leftover food. So, that being said, the color often varies between bird […]
Jellies don’t technically float; they’re neutrally buoyant (or close to it). Floating would be bad. It would mean being stuck on the surface, like a boat. Jellies are mostly water-up to 96%. What’s left is mostly the “jelly” in a jellyfish, the mesoglea. Jellies sink exceedingly slowly, and make up for it with just a […]
An animal lives to eat and breed. In order to do this, some animals that call the ocean habitat ‘home’ have to travel great distances to find food or reach a particular breeding ground. Here is a breakdown of some of the most impressive migrations in and around the sea. Perhaps the longest migration of […]

This past Friday I had a particularly curious and enthusiastic fifth block Oceanography class. All of their questions were marine science related so I broke out some notecards and asked them to write all of their burning inquiries down. I wanted to tackle them thoughtfully … here I am! My students are amazing inspiration and […]
