Leiogalathea Samudragiri

Leiogalathea Samudragiri
  1. Indian researchers discovered a new species of squat lobster named Leiogalathea samudragiri in deep waters (360 metres below sea level) near Minicoy which is part of the Lakshadweep island group.
  2. It was found during a research cruise conducted under India’s Deep Ocean Mission (Samudrayaan programme) which focuses on exploring deep marine environments, mapping the seabed, and studying ocean biodiversity.
  3. About Squat Lobsters:
    1. Squat lobsters are marine crustaceans that look like small lobsters, but they are not true lobsters.
    2. They are more closely related to hermit crabs and porcelain crabs.
    3. There are over 900 known species worldwide. They inhabit almost every type of marine environment, from shallow reefs to deep oceans, across many latitudes.
    4. Their bodies are small and flattened, usually measuring between 0.7 and 3.5 inches.
    5. As decapods, they possess ten legs, with the front pair being very long and ending in large claws.
    6. They keep their tail folded under the body, giving them a short, “squat” appearance, which is how they got their name.
    7. Like many crustaceans, squat lobsters can rapidly flick their tail to propel themselves backwards, allowing quick escape from predators.
  4. Unique features of the species:
    1. It has smooth, continuous ridges on the upper shell, unlike similar species where these ridges are broken.
    2. Exactly six horizontal ridges are present on the rear half of its body.
    3. A particular spine on the antennules (feelers)—normally seen in related species—is completely absent.
    4. The animal is bright orange, making it visually distinct.
