Sexy Sea Slugs.

Nudibranchs  are becoming somehow attractive water pets maybe an answer to new materials as they may look like creatures from another universe.
But these multi-coloured sea slugs are in fact one of the marvels of our oceans. Nudibranchs are soft-bodied marine molluscs that shed their shells after their larval stage, revealing their brightly-coloured exteriors. These stunning images were captured by wildlife photographer Franco Banfi.
As there featured in some of Earth's most exotic waters surrounding Indonesia, the Phillippines, Papua New Guinea, the Mediterranean and the Red Sea. These alien-like creatures can be found in oceans all over the world. Nudibranchs shed their shells during the larval stage to reveal these multi-coloured exteriors.
It is believed the soft-bodied marine molluscs have evolved their unique anatomy to warn off predators. As they like colourful alien creatures living at the bottom of the sea and really look very attractive also be seen in sea pools. The underwater slugs which use their bright body armour to fend off predators.  Nudibranchs are soft-bodied marine molluscs which shed their shells. Name derives from Latin and Greek and means 'naked gills'. Scientists believe remarkable colouring is a form of self-defence. These images were taken in waters surrounding Indonesia, the Philippines and Papua New Guinea, as well as the Mediterranean Sea and Red Sea.

The name 'nudibranchs' derives from Latin and Greek and means 'naked gills'.
The name derives from the Latin for naked, nudus, and the Greek for gills, brankhia. In most species the gills are prominently displayed on their dorsal surface.Scientists believe they may have evolved such extraordinary anatomy as a form of camouflage to mimick their surroundings and avoid predators.
Another theory is that they are an example of aposematism, an attempt to warn potential predators that they could be poisonous to eat. Even their egg masses are often red, pink, orange or any other colour depending on the species. In tropical waters, beachwalkers can find nudibranchs in tidal pools at low tide.
One theory is that the colourful exterior is a form of aposematism - a warning to predators that they could be poisonous. Another theory is that their bright colouring helps sea slugs blend into their surroundings. Wildlife photographer Franco Banfi travelled around the world to capture these beautiful images. There are thought to be around 3,000 different species of nudibranchs in our oceans. Nudibranchs live on all levels of the ocean but their greatest size and variation comes in warm, shallow waters.

Some Nudibranchs have toxins which can render their predators incapacitated. Some species get their toxicity from the sponge they eat but others can produce it themselves.

Another defence tactic is for nudibranchs to release acid from their skin. Nudibranchs are among the most beautiful and diverse creatures to be found on the planet. In most species, the gills are prominently displayed on their dorsal surface. Some species can also release toxins which render their predators incapacitated and allow them to escape.

Others can release acid from their skin when irritated. There are more than 3,000 described species of nudibranchs and they occur in oceans worldwide including both tropics and Antarctica. They can be found crawling over rocks, seaweeds, sponges, corals and many other substrates. They live in all levels of saltwater but their greatest size and variation occurs in warm, shallow waters.
Sea slugs have tentacles on their heads which they use to find food and seek a mate. They can be found crawling over rocks, seaweeds, sponges, corals and many other substrates. Sea slugs are found all over the world, including the British Isles, the tropics and even the Antarctic. Nudibranchs are generally hermaphrodites this means that they possess both male and female sex organs. Even sea slug eggs can be red, pink, orange or any other colour depending on the species. Beach walkers can often find nudibranchs in tidal pools at low tides.
