COLOURFUL NUDIBRANCHES – You will think you are hallucinating…
- A nudibranch is a member of the Nudibranchia, a group of soft-bodied, marine gastropod mollusks which shed their shells after their larval stage.
- They are noted for their often extraordinary colours and striking forms.
- Currently, about 2,300 valid species of nudibranchs are known.
- Nudibranchs are often casually called sea slugs, but many sea slugs belong to several taxonomic groups which are not closely related to nudibranchs.
COWRIE SHELLS – More than just the pretty shell on the beach
- Cowries are egg-shaped with a flat base and a narrow opening.
- Their shells are smooth and highly polished.
- They protect their glossy finish by wrapping their brightly colored mantle lobes nearly completely around their shells when they move.
AND THE BIG ONE….
WHALE SHARK – NOT YOUR NORMAL SHARK – Thanks heavens…
But the most amazing experience to see one on a dive – try it – you will remember it for ever and a day!
-
- The whale shark (Rhincodon typus) is a slow-moving filter feeding shark
- the largest known extant fish species.
- The largest confirmed individual had a length of 12.65 m and a weight of approximately 21.5 metric tons), and unconfirmed reports of considerably larger whale sharks exist.
- The whale shark holds many records for sheer size in the animal kingdom, most notably being by far the largest living nonmammalian vertebrate.
- The species originated about 60 million years ago.
- The whale shark is found in open waters of the tropical oceans and is rarely found in water below 71 °F (22 °C).
- Modeling suggests a lifespan of about 70 years but measurements have proven difficult.[3] Whale sharks have very large mouths and are filter feeders, which is a feeding mode that occurs in only two other sharks, the megamouth shark and the basking shark.
- They feed mainly on plankton and are generally considered harmless to humans
