These different types of jellyfish in Texas are considered planktonic and will be found in the water column from the surface to much deeper depths.

Unlike other ocean dwellers, these unusual animals don’t use their swimming tentacles to prop themselves through the water.

Instead, the many hairlike cilia on their underside keep them afloat!

2. Pink Meanie Jellyfish

The most venomous jellyfish in the world can be found in Texas water. It is usually 5-6 inches long but can grow to a foot.

Its bell is clear and grayish pink, shaped like an inverted pear or egg yolk, hence its other name of a pink meanie. 

A ruffled, tangled webbing sits between the tentacles and its Phyllida, which are finger-like projections. This is one of the types of jellyfish in Texas that makes its home all along the East Coast.

Though they have powerful venom that causes severe pain and can lead to death within minutes, they’re not aggressive and rarely come near humans.

The Portuguese Man-o-War is one of the different types of jellyfish in Texas.

They are found mainly in temperate and tropical regions. It floats on the water’s surface with its purple-striped tentacles trailing behind it.

This animal uses stinging cells to paralyze and kill prey and catch their dinner, which they suck up through their mouth-like grooves on the underside of their body.

Interestingly, this animal will even sting sharks, seals, otters, dolphins, and whales that come too close to them for dinner.

They are not typically considered life-threatening but can cause much discomfort due to their intense pain and formication symptoms (paralysis).

Sea nettles are one of the types of jellyfish in Texas. They are stinging invertebrates that live all over the world.

They are often hard to see and look like small seaweed that pulsates back and forth.

Sea nettles have long trailing tentacles up to four feet long, which trail behind them when they swim and capture their prey, which includes shrimp, fish, crabs, and even other jellyfish. 

As sea nettles consume food for themselves, they also leave behind nutrients for other wildlife and add oxygen to the water.

The most dangerous part about sea nettles is their sting, known to paralyze people if stung repeatedly or if they are sensitive to injuries or conditions such as allergies.

6. Moon Jelly
