Today in science I went on a trip to a reef to do a survey. I chose to do the crab survey.
One thing I found interesting was how you know what sex a crab is, more specifically an iron crab. You can tell by the underside being either sharp or more rounded. If rounded then the crab would be a female and if sharper than it’s male. I only found two females.
One thing I didn’t like was almost falling over a bunch of times because of the slippery and small movable rocks. Another thing would probably be someone bringing a crab on the bus.
One thing I did well was whenever I lifted up a rock I’d make sure to put it back down in the same place and not crush any crabs that would be underneath.
I liked learning about the crabs and other wildlife. It has definitely enhanced my interest in marine biology.
