Exploring the Rocky shore :: Explorar as poças de maré

Yesterday we took part on the Bioblitz organized by the school of biology of the University of St. Andrews. It was a fun day dedicated to species identification, from creatures on shore pools to plants, birds and pond life.

We spent most of the morning exploring the shore pools: the tide was incredibly low and it was amazing to discover so many species. There were lots of sand eels swimming around in schools and we actually caught a few.

Someone found a weaver fish which usually hide in the sand. Stepping on them is a very unpleasant experience as they are venomous and it can be very painful, but looking at it was actually nice. We also found quite a few hermit crabs of different sizes and they were very active when they found themselves in the sample bucket. Hermit crabs don’t have their own shell so they adopt shells which previously belonged to other animals.

Among our finds there were also a common starfish and a green crab. It was really exciting to meet so many animals in their environment. The team from the biology school was also very happy with all the samples they took back to the lab.  Below are some photos of our findings: I hope that you enjoy them!

Ontem participamos no Bioblitz organizado pelo departamento de biologia da universidade de St. Andrews. Foi um dia divertido dedicado a identificar espécies, desde criaturas nas poças de maré a  plantas, pássaros e criaturas de água doce.

Passámos a maior parte da manhã a explorar as poças de maré: a maré estava incrivelmente baixa e foi fantástico encontrar tantas espécies. Havia cardumes de galeotas a nadar por entre as rochas e conseguimos apanhar algumas.

Alguém encontrou um peixe-aranha escondido na areia. Pisar um deles pode ser bastante doloroso mas ver um exemplar foi muito giro. Também encontrámos alguns bernardos-eremitas de diferentes tamanhos e estavam muito activos no nosso balde de amostras.. Os bernardo-eremitas não têm casca própria e adoptam as cascas que pertenceram a outros animais.

Entre os nossos achados também estava uma estrela-do-mar e um caranguejo. Foi espectacular conhecer tantos animais no seu próprio ambiente. A equipa do departamento de biologia estava bastante animada com as amostras que levaram de volta ao laboratório. Deixo-vos algumas fotos dos nossos achados: espero que gostem!
