Peltodoris atromaculata Reproduction

When we explore our underwater reefs we are often amazed by the number of species that we find in a few square meters and as in this case even in a few square centimeters. We have said it many times that biodiversity makes a habitat and an ecosystem more stable, solid and long-lasting. Often we fail to realize the quantity of different species that live next to each other and obviously it is almost impossible to know and recognize them all.

Adanson's slit shell

While snorkeling along a stretch of coral reef on Redang Island in Malaysia we found this Adanson's slit shell in a few meters of seabed. The encounter, quite unusual given that the mollusc lives at great depths, is due to the fact that it was probably brought there by some deep-sea fisherman while cleaning the fishing nets...

Common octopus

Octopus is considered one of the most intelligent animals that we can encounter in our Mediterranean Sea. As you can see, it is a champion of camouflage, cunning and escape strategies. However, it also has its problems and if once camouflaged it is practically impossible to see even to the most expert eyes, a spoilsport fish like the Serranus scriba (Painted comber) ...

Ostrea Neopycnodonte cochlear

Neopycnodonte cochlear is a species of marine bivalve molluscs belonging to the family Gryphaeidae.This species can be found in the North Atlantic Ocean (Azores) and in the Mediterranean Sea. The peculiarity we want to point out is that it is a small oyster that plays the same role as corals. That is, it forms aggregations as they grow and multiply, create agglomerations of more or less large dimensions comparable to corals.

Noah's Ark seashell

Noah's Ark seashell, Arca noae, is a species of bivalve mollusc in the family Arcidae. It is found in the Mediterranean Sea from low tide mark to a depth of 100 metres. The seashell of Arca noae grows to about 10 cm in length. but the ones we found did not exceed 3, 4 centimeters. Quite difficult to identify on the seabed because the shells are always covered not only by sponges but also by algae or other encrusting organisms. We noticed their presence because they were found open without the presence of the mollusc which was certainly prey to either an Octopus or fish such as Sea bream and Bream.

Spondylus gaederopus is a species of marine bivalve mollusc, a thorny oyster in the family Spondylidae. This species is endemic to the Mediterranean Sea. Spondylus gaederopus attaches itself to the substrate with its lower valve, which is usually white, while the upper valve is usually purple. Specimens that are all white, or all purple do, however, exist.

Giant triton

Meeting Giant triton - Charonia tritonis - always arouses a strong emotion, both because it is the largest mollusk in the Mediterranean Sea and because it is increasingly rare. Fortunately here on intotheblue.it we have published several videos of this splendid shell so despite all the alarms we give about the health of our sea, when we encounter the Triton the hope that the sea can really regenerate itself returns to be present. ...

Luria sea snail

Meeting Luria lurida is becoming more and more difficult, then finding the shell with the mollusc inside alive is practically a very rare event. In the video we obviously see the Cyprean shell without the animal but given the sheen of the shell this mollusk was probably recently eaten by some predator, probably the usual octopus. ...

Murex trunculus or Hermit crab?

Often while snorkelling it happens to find some shells and in the Mediterranean it is easy to meet the Murex shell only that we do not always find the mollusk inside, Murex trunculus or Hexaplex trunculus, but the classic Hermit crab which has appropriated a bigger, more beautiful but above all safer house.  We have probably found the Clibanarius erythropus, red-legged hermit crab, devil hermit crab or coast hermit crab, one of the most common hermit crabs in the Mediterranean but rarely of such dimensions as to be able to easily drag a shell like that of the Murex. ...

Curiosity of the octopus

Common octopus, Octopus vulgaris, is an extremely curious animal towards everything that happens in its territory and this makes it one of the most intelligent species in the underwater world. In this video we see him emerge from his den intent on studying the camera specially placed on the seabed to test his curiosity.We identified it thanks to the presence of some fish such as the Sciarrano (Serranus scriba) and Donzella pavonina (Thalassoma pavo), intent on scrutinizing its den probably waiting for some food waste. ...

We publish another encounter with the Sea hare, Aplysia depilans, this time which took place on a depth of about 42/45 meters. We are on a not very high rock wall about 4/5 miles from the coast where, due to the now increasingly present mucillage, animals and marine organisms seem to have disappeared. ...

Charonia tritonis - Giant triton

We are on some isolated rocks at a depth of 40/46 meters, where we have found two beautiful specimens of Charonia tritonis, Giant mediterranean triton.  This is the mollusk and consequently the largest shell in the Mediterranean Sea. In this dive we met two of them, we filmed the first one casually on the wall we were exploring, we realized watching the footage that we passed by without seeing it. The second was inside a hole from which we moved it to try to film it better. ...

Octopus vulgaris - Common octopus

We have filmed Common octopus, Octopus vulgaris, several times on intotheblue.it but each encounter with this cephalopod mollusk is always unique and different from the previous ones. In this case, in fact, the octopus was so well camouflaged on the seabed that it was not possible to see it from just a few meters below the surface. ...

The struggle for life

This video made in the Maldives shows us an octopus as it comes out of its den to go hunting for food. While out he is attacked by a redtoothed triggerfish and thent has to give up his lunch and immediately take shelter in an emergency shelter to try to save himself. The video is interesting because it highlights the struggle for life that occurs every day in nature and where the predator must necessarily be careful to prevent becoming the prey of another animal.
