I got this cactus this weekend, but when I look it up online it's not the same as what's pictured. Any idea what it may be? Thank you!!!

It is a crested cactus - these are usually some kind of mutation that makes it grow in unexpected forms. From the flower it looks like it is a hybrid from the greater Echinopsis family as the name Echinobivia already implies: it is a combination of Echinopsis and Lobivia, so in all likelihood those are the parent plants that led to this particular crested hybrid. So it could be a crested form of the Echinopisis x Lobivia 'Rainbow bursts' hybrid - the 'Rainbow bursts' name is the cultivar name, some of these are very well established with well established characteristics in which the flower color and appearance usually play a huge role, while others may be harder to find good information for either because they are new or the name has been applied in error.
From the description on the pot I would think that 'Rainbow bursts' is applied to a bunch of different plants by the grower that do not necessarily will have the same flower color, which is not really how a cultivar name should be applied.

Its an Echinopsis x Lobivia hybrid shortened to Echinobivia.

Repot so that the entire green part is sitting ABOVE the soil, instead of IN the soil. If you need to, put a couple pebbles under the 'wings' to hold them off the soil. They are very prone to rot.

Edited to add: That's right - they come in several colors, all neon.

Thank You! Thank You! @mcvansoest and @Daisyl
I appreciate all of the information on my new addition! I'll be sure to repot it to keep it from rotting. Is there anything else I should know about it? I'm doing some research on it now as well.

In my experience these crested plants tend to be a little more sensitive to overwatering than their regular counterparts, so I would be careful with watering them. It looks like you have it in a pot with another cactus, depending on the water needs of that plant that may or may not work.

Thank you @mcvansoest! I'll be sure to keep an eye on it and see if it needs to be placed on its own. I currently have it in a large planter with a small Euphorbia trigona and some very small succulents.
