Marine Life with Brenda

Blennies   If you enjoy rock-pooling you've probably came across these marine creatures. Blenny is a vague name which have been extended to various marine, brackish, and some freshwater fish families that share similar morphology and behaviour. Only a small proportion of them, to be more precise, six families are considered "true blennies," both grouped in the order Blenniiformesa and their members are called blenniiformids.  Blennies are a capable of breathing out of water since they are able to maintain a moist external layer and are adapted  the normal changes of cycles of rockpools.  Author: Brenda Moita

Cuttlefish Cuttlefish ( Sepia officinalis ) are masters in altering their appearance in order to blend into their environment. But the cephalopods can no longer hide their inner thoughts, thanks to a technique that tracks the ever-changing patterns on their skin which infers the brain activity of a cuttlefish.  Cuttlefish  camouflage themselves by contracting muscles around thin, coloured skin cells called chromatophores. The cells come in multiple colours and act as pixels through the body of the cuttlefish, shifting their scale to change the pattern on the surface of the mammal.  Author: Brenda Moita
