Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

clawfooted marine isopod

The Clawfooted Marine Isopod belongs to the crustacean order Isopoda, a diverse group of aquatic and terrestrial arthropods with flattened, segmented bodies and seven pairs of walking legs. Marine isopods occupy a vast range of habitats from intertidal zones to hadal trenches, and many species are adapted to specific substrates, host organisms, or depth ranges. Species commonly referred to as clawfooted isopods often belong to families such as Gnathiidae, Cirolanidae, or Aegidae, characterized by robust, claw-tipped pereopods used for grasping substrate or hosts. Many marine isopods are scavengers or detritivores, consuming decomposing organic matter on the seafloor, while others are parasitic on fishes or invertebrates. The segmented exoskeleton is periodically molted as the animal grows. Marine isopods are important components of benthic food webs, serving as prey for fishes, crabs, and other invertebrates, while also contributing to the decomposition of organic matter. Specific information on the Clawfooted Marine Isopod's distribution, ecology, and conservation status depends on the exact species referred to, as the common name may apply to more than one species within this large and taxonomically complex order.
