How many sea slugs are there in the world?

Where does a sea slug live?
Sea slugs, or the nudibranch, is known to live in almost all water bodies across the globe. Nudibranchs are most seen living deep inside water bodies like the oceans and seas.

Umbraculum umbraculum is a slug species found in eastern Australia. Since some of the nudibranchs have evolved over the years to live out of the water, they are no longer able to live in water and may even drown.

How long does a sea slug live?
The life span of a sea slug, or the nudibranch, varies in different species. Some of the species are known to live for one year, but other species like the Dolabella auricularia can live for about six years when kept in an aquarium. The Cephalaspidean philine gibba is known to have a lifespan of four to five years.
How do they reproduce?
Sea slugs are known to have both male and female reproductive organs. This helps them mate with any individuals of the same species. All sea slugs have a jelly-like tube with a sharp tip which is called a penile stylet and it punctures the other's skin. This penile stylet then releases a mix of secretions made by the prostate gland into the other sea slugs body. The female then lays eggs and these eggs can take between five to 50 days to transform into free larvae. The number of eggs that the female lays can be different in different species of sea slugs. A few of the species are also able to reproduce asexually.
What is their conservation status?
The current conservation status of sea slugs, which are also known as the nudibranch, is Not Extinct. According to the information, there are around 3,000 different species of sea slugs living inside and outside all forms of water bodies that present on the planet.
