The start of the surf fishing season has already brought reports of jellyfish sightings and stings. There have been several beach closures in Sinaloa state of Mexico due to thousands of sting reports; and in South Carolina, a few Portuguese man-of-wars (algae relatives with painful stings) washed ashore.
These fascinating invertebrates are scarier than they seem due to their poorly understood characteristics. Jellyfish are among the oldest living creatures on Earth. The phylum Cnidaria, which contains most jellyfish, contains over 10,000 species of jellyfish. Take a moment to enjoy these fun jellyfish facts. Explore the bizarre, fascinating world of these bizarre gelatinous creatures.
What Are Jellyfish?
A jellyfish is a water animal. Jellyfish are not fish and belong to a different phylum than fish. The word “jellyfish” is an umbrella term for animals called jellies, sea jellies, or marine jellies. Jellyfish are classified within the phylum Cnidaria, which also includes sea anemones and corals. Sea anemones and jellyfish both have a body structure called a hydra. Corals and jellyfish have a very different body structure.
Jellyfish aren’t fish. Fish have a backbone, or a spinal column. The defining characteristic of a jellyfish is its lack of a backbone. Jellyfish lack a true brain, heart, and muscles. Jellyfish have a lot of other specialized traits, but they don’t have a backbone. The plural of jellyfish is jellyfish, not jellyfishes.
Jellyfish Aren’t Even Fish
Are jellyfish fish? No. Jellyfish aren’t fish. Fish are vertebrates, meaning they have backbones. Jellyfish are invertebrates, because they lack a backbone.
Certain Jellyfish Can Be Used As Bait For Fishing
Several types of jellyfish are actually used as bait for fishing, including the moon jellyfish, the rainbow jellyfish, and the gold-lined jellyfish. Fishermen use the moon jellyfish as live bait for catching many types of fish. The rainbow jellyfish are used as live bait for catching tuna, marlin, and other types of large fish. The gold-lined jellyfish are used as bait for catching swordfish.
Water Makes Up Almost All Of [email protected]
Jellyfish are very different from other types of animals. One big difference is that jellyfish are made almost entirely of water. The bell of a jellyfish is an outer layer called a “siphonophore.” It’s made up of multiple parts called “brachiolaria.” Jellyfish have no stomach or digestive tract.
There Are More Than 25 Types Of Edible Jellyfish
Jellyfish are popular in Chinese cuisine. The most well-known type of edible jellyfish is the flying jellyfish. The flying jellyfish is actually a type of jellyfish called a “true jellyfish.” The flying jellyfish is the most popular edible jellyfish.
Most jellyfish are not edible. The main problem with eating jellyfish is that they are poisonous. Most jellyfish are inedible because they are poisonous. The toxins in jellyfish are made to protect the jellyfish. Toxic chemicals are in the skin of the jellyfish, not its meat.
All Oceans Contain Jellyfish
Jellyfish are found in all of the world’s oceans. The Atlantic Ocean is home to the most jellyfish, but jellyfish are found in all worlds major oceans. Jellyfish live in the Atlantic Ocean, the Pacific Ocean, and the Indian and Arctic Oceans. Jellyfish live in all of the major oceans.
Jellyfish Move Slowly
Jellyfish move very slowly. Jellyfish don’t have muscle and can’t move on their own. Jellyfish don’t use their own muscles to move. Jellyfish use ocean currents and tides to move around. Jellyfish drift with the currents to get around. Jellyfish can drift along at up to 4 knots.
Several Types Of Jellyfish Are Capable Of Killing A Fully Grown Person
Several types of jellyfish have stings toxic enough to kill a person. A person who is stung by a box jellyfish may die within a few minutes. Box jellyfish have a lethal poison in their tentacles. The box jellyfish of the genus Chironex are the most deadly jellyfish, but there are other species that have toxic stings.
Box jellies are the most notorious jellyfish. It’s possible to die from a box jellyfish sting. Box jellyfish are also called sea wasps. These are the most dangerous jellyfish. A sting from a box jellyfish can be fatal.
Fish And Jellyfish Feed On Each Other
In the open ocean, it’s a eat or be eaten world. Not only will jellyfish feed on fish that get too close, but certain species of fish will also attack and eat jellyfish. The lionfish is a fish that eats jellyfish. The lionfish has a long, poisonous spine. It uses this spine to stab and kill other animals, including other fish and jellyfish.
While we can’t say you now “know everything” about jellyfish, we do hope you understand them a bit better. Jellies are a fascinating and diverse group of sea creatures. Considering how delicate they are, they have a surprising amount of specialized traits. They have a unique body structure, a shared shared trait with sea anemones and corals.
