Hi, I'm Andrew and I’m just a simple 19 year old guy and zoology student that posts random factoids about obscure animals and general animal science/zoology/biology stuff so if you like animals this is the place for you, if you only like cute animals this is not the place for you… Also I can ID any animals you might need identified (just submit them to me).

Disclamer: none of the pictures are mine unless stated

Family Polioptilidae: A family of passerine birds commonly known as "Gnatcatchers". All gnatcatchers are native to the New World, being found in both North and South America. Gnatcatchers are close relatives of the wrens and some species are known as "Gnatwrens".

Reticulated Brittle Star (Ophionereis reticulata)

…a species of ophionereidid brittle star that inhabits the shallow waters of the Western Atlantic, Caribbean Sea and Gulf of Mexico. Like other brittle stars O. reticulata is a herbivore and filter feeder, feeding mainly on red/green algae and diatoms. These food items are caught by the star raising its arms into the water current (while keeping its disc concealed) and catching passing ‘prey’. Unlike other brittle stars O. reticulata uses its tube feet in locomotion. Its tube feet are long and pointed and when in movement are raised from the sea bed allowing the star to move at speeds of 50 cm per minute.

Classification

Animalia-Echinodermata-Ophiuroidea-Ophiurida-Ophiurina-Ophionereididae-Ophionereis-O. reticulata
