  • A Limacia clavigera that feeds excusivly on a bryazoan that covers the surfaces of kelp fronds, like 9the one pictured. Another temperate water species, this one was phoptographed in the cold clear waters off Norway

  • A Goniobranchus aureopurpurea nudibranch lifts its "skirts" or mantle as it moves across the bottom. The animal's rhinophores are able to sense chemicals and currents within the water around it.

  • Close up stady of the rhinophores of a Marie's Mexichromis nudibranch. (Mexichromis mariei). These sensory organs provide a great deal of information about chemical and scents in the water as well as currents and water movements. Taken in the Lembeh Straits, Sulawesi, Indonesia.

  • Risbecia tryoni nudibranchs apparently nuzzle priot to mating. It is likely that they are actually using the chemical receptors on their rhinophores to sense the readiness of the other.

  • This Marie's Mexichromis (Mexichromis mariei) is laying a trail or ribbon of eggs. Each species of nudibranch has a distinct pattern when it lays eggs and this allows biologists to identify which eggs belong to which animal.

  • A Polycera quadralineata nudibranch strikes a pose on a kelp frond. Species from temperate regions of the world still display the bright colorations of their warmer water relatives.

  • There are still many species of nudibranch that are as yet undescribed by science. This animla rejoices in the name Nembrotha species 2 and is not yet properly taxonomically classified. The use of genetic sequencing has also created many new controversies, with many existing families and species being reclassified. This partcular specimen has tangled with something that has removed one rhinophore.

  • Two Phyllidia marindica nudibranchs prepare to mate. These animals are widespread throughout the Indian and Pacific Oceans.
    161005-ahanlon-508442.jpg
  • A bus stop nudibranch (Goniobranchus hintuanensis) lifts its mantle or skirt as it negotiates the sea floor. These species were re classified with the help of DNA analyisis in 2012. Nudibrachs move with the help of a muscular foot, that has rythmic contractions along its length.

  • A Nembrotha purpureolineata feeds as it moves across the seabed. In common with many sea slugs, they are specialised eaters, only feeding on tunicates or sea squirts.

  • Like a ship plowing its way across the ocean's surface, this many lobed ceratosoma (Ceratosoma tenue) moves across the sea bed.
    161001-ahanlon-506211.jpg
  • The vibrant colors of this Hypselodoris apolegma, attempt to warn other animals that it may not be so good to eat.
    161011-ahanlon-500775.jpg
  • Nudibranchs lay chacteristic patterns of eggs on rocks or the sea bed. This many lobed ceratosoma (Ceratosoma tenue) is layinga spiral of red eggs on a small rock
    131022-ahanlon-82070.jpg
  • The red on this Nembrotha kubaryana signal danger to any passing animla that thinks that it might be a good meal!

  • This Marie's Mexichromis (Mexichromis mariei) is laying a trail or ribbon of eggs. Each species of nudibranch has a distinct pattern when it lays eggs and this allows biologists to identify which eggs belong to which animal.
    161003-ahanlon-507096.jpg
  • A girdled Glossodoris (Glossodoris cincta) nudibranch makes its way across the sea bed. Nudinbranchs use muscular contractions of their mantles to undulate and allow them to move.
