Anglerfish

Class: Ray-Finned Fish (Actinopterygii)
Order Lophiiformes
Conservation status: Various

Anglerfish are deep-sea fish known for their distinctive bioluminescent lure, which dangles in front of their mouths to attract prey in the pitch-black ocean depths. These “ugly” fish are typically small, with some species exhibiting extreme sexual dimorphism, where the females are much larger than the males. Adapted to life in the abyssal zone, anglerfish possess a unique and fascinating biology that allows them to thrive in one of Earth’s most inhospitable environments.

Aye-Aye

Scientific name: Daubentonia madagascariensis
Class of animal: Mammal
Family: Strepsirrhini
Conservation status: Endangered

Lemurs are a group of primates found only on the African island country, Madagascar. Of the hundred or so species of lemur, the aye-aye is without a doubt the strangest. This nocturnal primate prowls the forests of Madagascar under the cover of darkness. It taps on trunks and branches with its bone-like middle finger, using echolocation known as “percussive foraging”. The aye-aye’s odd appearance and behavior have unfortunately led to it being viewed as a bad luck omen.

The blobfish’s gelatinous body, with low density, allows it to float above the sea floor without using energy to swim. Although its appearance is distorted when brought to the surface, the blobfish is a unique and fascinating inhabitant of the deep sea.
